NCC PDI 2022 pitch competition winners

Five winners selected in prestigious pediatric device competition

The National Capital Consortium for Pediatric Device Innovation (NCC-PDI) announced five awardees chosen in its prestigious “Make Your Medical Device Pitch for Kids!” competition. Each received a share of $150,000 in grant funding from the U.S. Food and Drug Administration (FDA), with awards ranging from $20,000 to $50,000 to support the advancement of pediatric medical devices.

Consistent with its mission of addressing the most pressing pediatric device needs, this year’s competition, moderated by MedTech Innovator, welcomed medical device technologies that address the broad unmet needs of children. The pediatric pitch event was part of the 10th Annual Symposium on Pediatric Device Innovation, co-located with the MedTech Conference, powered by AdvaMed.

This year’s pediatric device innovation awardees are:

  • CorInnova – Houston, TX – Minimally invasive biventricular non-blood contacting cardiac assist device to treat heart failure.
  • Innovation Lab – La Palma, CA – Mechanical elbow brace stabilizes tremors for pediatric ataxic cerebral palsy to improve the performance of Activities of Daily Living (ADLs).
  • Prapela – Biddeford, ME – Prapela’s incubator pad is the first innovation to improve the treatment of apnea of prematurity in over twenty years.
  • Tympanogen – Richmond, VA – Perf-Fix replaces surgical eardrum repair with a nonsurgical clinic procedure
  • Xpan – Concord, Ont. – Xpan’s universal trocar enables safest and most dynamic access and effortless upsizing in conventional/mini/robotic procedures.

“We are delighted to recognize these five innovations with critical NCC-PDI funding that will support their journey to commercialization. Improving pediatric healthcare is not possible without forward-thinking companies that seek to address the most dire unmet needs in children’s health,” says Kolaleh Eskandanian, Ph.D., M.B.A, P.M.P, vice president and chief innovation officer at Children’s National Hospital and principal investigator of NCC-PDI. “We know all too well how challenging it is to bring pediatric medical devices to market, which is why we have created this rich ecosystem to identify promising medical device technologies and incentivize investment. We congratulate this year’s winning innovators and applaud their efforts to help bridge these important care gaps that are impacting children.”

Empowering Innovators

NCC-PDI is one of five consortia in the FDA’s Pediatric Device Consortia Grant Program created to support the development and commercialization of medical devices for children, which lags significantly behind the progress of adult medical devices. NCC-PDI is led by the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National and the A. James Clark School of Engineering at the University of Maryland, with support from partners MedTech Innovator and design firm Archimedic.

A pediatric accelerator program, powered by MedTech Innovator, the largest medical device accelerator in the world, is a key part of the network of resources and experts that NCC-PDI provides in support of pediatric innovators. All five of this year’s competition finalists had an opportunity to participate in the year-long accelerator program.

To date, NCC-PDI has mentored 250 medical device projects to help advance their pediatric innovations throughout all stages of the total product life cycle (TPLC).

Eskandanian adds that supporting the progress of pediatric innovators is a key focus of the new Children’s National Research & Innovation Campus, a one-of-its-kind ecosystem that drives discoveries that save and improve the lives of children. On a nearly 12-acre portion of the former, historic Walter Reed Army Medical Center in Northwest Washington, D.C., Children’s National has combined its strengths with those of public and private partners, including industry, universities, federal agencies, start-up companies and academic medical centers. The campus provides a rich environment of public and private partners which, like the NCC-PDI network, will help bolster pediatric innovation and commercialization.

AI may revolutionize rheumatic heart disease early diagnosis

echocardiogram

Researchers at Children’s National Hospital have created a new artificial intelligence (AI) algorithm that promises to be as successful at detecting early signs of rheumatic heart disease (RHD) in color Doppler echocardiography clips as expert clinicians.

Researchers at Children’s National Hospital have created a new artificial intelligence (AI) algorithm that promises to be as successful at detecting early signs of rheumatic heart disease (RHD) in color Doppler echocardiography clips as expert clinicians. Even better, this novel model diagnoses this deadly heart condition from echocardiography images of varying quality — including from low-resource settings — a huge challenge that has delayed efforts to automate RHD diagnosis for children in these areas.

Why it matters

Current estimates are that 40.5 million people worldwide live with rheumatic heart disease, and that it kills 306,000 people every year. Most of those affected are children, adolescents and young adults under age 25.

Though widely eradicated in nations such as the United States, rheumatic fever remains prevalent in developing countries, including those in sub-Saharan Africa. Recent studies have shown that, if detected soon enough, a regular dose of penicillin may slow the development and damage caused by RHD. But it has to be detected.

The hold-up in the field

Diagnosing RHD requires an ultrasound image of the heart, known as an echocardiogram. However, ultrasound in general is very variable as an imaging modality. It is full of texture and noise, making it one of the most challenging to interpret visually. Specialists undergo significant training to read them correctly. However, in areas where RHD is rampant, people who can successfully read these images are few and far between. Making matters worse, the devices used in these low resource settings have their own levels of varying quality, especially when compared to what is available in a well-resourced hospital elsewhere.

The research team hypothesized that a novel, automated deep learning-based method might detect successfully diagnose RHD, which would allow for more diagnoses in areas where specialists are limited. However, to date, machine learning has struggled the same way the human eye does with noisy ultrasound images.

Children’s National leads the way

Using approaches that led to successful objective digital biometric analysis software for non-invasive screening of genetic disease, researchers at the Sheikh Zayed Institute for Pediatric Surgical Innovation, including medical imaging scientist Pooneh Roshanitabrizi, Ph.D., and Marius Linguraru, D.Phil., M.A., M.Sc., principal investigator, partnered with clinicians from Children’s National Hospital, including Craig Sable, M.D., associate chief of Cardiology and director of Echocardiography, and cardiology fellow Kelsey Brown, M.D., who are heavily involved in efforts to research, improve treatments and ultimately eliminate the deadly impacts of RHD in children. The collaborators also included cardiac surgeons from the Uganda Heart Institute and cardiologists from Cincinnati Children’s Hospital Medical Center.

Dr. Linguraru’s team of AI and imaging scientists spent hours working with cardiologists, including Dr. Sable, to truly understand how they approach and assess RHD from echocardiograms. Building the tool based on that knowledge is why this tool stands apart from other efforts to use machine-learning for this purpose. Orienting the approach to the clinical steps of diagnosis is what led to the very first deep learning algorithm that diagnoses mild RHD with similar success to the specialists themselves. After the platform was built, 2,136 echocardiograms from 591 children treated at the Uganda Heart Institute fed the learning algorithm.

What’s next

The team will continue to collect data points based on clinical imaging data to refine and validate the tool. Ultimately, researchers will look for a way that the algorithm can work directly with ultrasound/echocardiogram machines. For example, the program might be run through an app that sits on top of an ultrasound device and works on the same platform to communicate directly with it, right in the clinic. By putting the two technologies together, care providers on the ground will be able to diagnose mild cases and prescribe prophylactic treatments like penicillin in one visit.

The first outcomes from the program were showcased in a presentation by Dr. Roshanitabrizi at one of the biggest and most prestigious medical imaging and AI computing meetings — the 25th International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI).

Lifesaving ICDs can cause anxiety, stress, PTSD for parents and kids

Paper cutout of head with brainwaves

Research shows that children with implantable cardioverter-defibrillators, and their parents, are at risk for anxiety, post-traumatic stress disorder and other psychological distress.

Recent advances in design and efficiency of implantable cardioverter-defibrillators (ICDs) have led to their increased use in younger patients, protecting more children with congenital heart disease from sudden cardiac arrest and sudden cardiac death, says a commentary in the journal Heart Rhythm. However, living longer with these devices and the day-to-day worry that they may have to deliver a lifesaving shock in the blink of an eye, may cause unusually high rates of anxiety, stress and other psychosocial distress for children with ICDs and their families.

Commentary authors Vicki Freedenberg, Ph.D., RN, electrophysiology nurse scientist, and Charles Berul, M.D., chief of cardiology, both from Children’s National Hospital, note that current available research shows both children with these ICDs and their parents are at risk for anxiety, post-traumatic stress disorder (PTSD) and other psychological distress. They highlight a new study published in the same journal that reports data related to prevalence and factors associated with PTSD in children with ICDs and their parents as a good start to better understanding these impacts.

Why it matters

Freedenberg and Berul say that the new study adds important information to an area without a lot of previous research. They also point out that understanding the long-term impacts of life with these devices is critical to ensuring the overall long-term health and wellbeing of both the children with these devices and their families.

What’s been the hold-up in the field?

The development of devices that work for younger children with congenital heart disease, including advances in ICDs and pacemakers, has increased in the last decade. In this time, studies of how these devices work for children have focused predominantly on clinical outcomes and questions related to clinical care.

As survival rates for children have increased, research needs to shift from the study of mortality and clinical outcomes toward understanding the full spectrum of how these devices impact daily life for these children and their families.

Moving the field forward

According to Freedenberg and Berul, the new study importantly includes both patient and parent perspectives, which is a first in this research area. They also offer recommendations for future studies, including the use of comparison groups to allow for generalization of findings. Researchers might also ask research questions to determine whether the device itself or the medical and non-medical factors that often occur simultaneously are more important to predicting mental health and wellbeing.

However, the commentary concludes with the most important takeaway: More research, with specific parameters focused on the impact of clinical interventions, is desperately needed to truly understand all the ways that children and their families are affected throughout life by the clinical care and support they receive.

JAMA study shows no benefit to nitric oxide in cardiopulmonary bypass for young children

Baby on ventilator

An international clinical trial showed that nitric oxide doesn’t help kids recover faster from cardiac surgery with cardiopulmonary bypass.

A study published in JAMA finds that the practice of introducing nitric oxide into the gas flow of the cardiopulmonary bypass oxygenator does not improve recovery or reduce the amount of time a child under age 2 needs to be on a ventilator after cardiac surgery.

Children’s National Cardiac Surgery Chief Yves d’Udekem, M.D., Ph.D., co-authored the international study, which is already leading to changes in how hospitals around the world care for children with congenital heart disease (CHD).

The results are from a double-blind, randomized controlled trial with more than 1,200 participants across six centers in Australia, New Zealand and the Netherlands. The research team found that children under age 2 who had cardiac surgery with cardiopulmonary bypass spent about the same number of days on ventilators after surgery, whether nitric oxide was used during surgery or not.

“These findings do not support the use of nitric oxide delivered into the cardiopulmonary bypass oxygenator during heart surgery,” the authors conclude.

What this means

Previous smaller, single center studies had shown early indications that nitric oxide delivered during heart surgery could possibly improve recovery and shorten the need for respiratory support after surgery by reducing the occurrence of low cardiac output syndrome in children under age 2.

This large-scale international trial showed that this is not the case.

Why it matters

Based on these earlier studies, many hospitals in the United States and around the world who perform critical heart surgery on young children with congenital heart disease had already started to incorporate nitric oxide into cardiopulmonary bypass. This new, more robust data is helping hospitals reassess this practice. Many are stopping it altogether based on the findings.

This work is an important reminder of how valuable well-designed, large-scale, double-blind, randomized, controlled trials are to defining, improving and refining best practices in clinical care.

Also, trials of this size and significance in pediatrics generally, and CHD specifically, take a very long time to complete, if they are ever able to be completed at all. That’s because the number of children with these conditions is relatively small and spread out, even though CHD is the most common birth defect in the world. The authors say it is a major accomplishment to have completed a trial of this size and  in such a short time. Even better, the data gathered from this sample of patients from across international borders can be used to provide even more insights into how best to care for these children as they continue to grow and develop.

caspase molecule

Caspases may link brain cell degeneration and cardiac surgery

caspase molecule

The review summarizes both the known physiological roles of caspases as well as some of the well-characterized neurotoxic effects of anesthetics in pre-clinical models.

A review article in the journal Cell Press: Trends in Neuroscience outlines the wide variety of cellular signaling roles for caspase proteins — a type of cellular enzyme best known for its documented role in the natural process of cell death (apoptosis). The authors, including Nemanja Saric, Ph.D., Kazue Hashimoto-Torii, Ph.D., and Nobuyuki Ishibashi, M.D., all from Children’s National Research Institute, pay particular attention to what the scientific literature shows about caspases’ non-apoptotic roles in the neurons specifically. They also highlight research showing how, when activated during a cardiac surgery with anesthesia and cardiopulmonary bypass, these enzymes may contribute to the degeneration of brain cells seen in young children who undergo heart surgery for critical congenital heart defects (CHDs).

Why it matters

The review summarizes both the known physiological roles of caspases as well as some of the well-characterized neurotoxic effects of anesthetics in pre-clinical models.

The authors propose that these non-apoptotic activities of caspases may be behind some of the adverse effects on the developing brain related to cardiac surgery and anesthesia. Those adverse effects are known to increase risk of behavioral impairments in children with congenital heart disease who underwent cardiac surgery with both anesthesia and cardiopulmonary bypass at a very young age.

This work is the first to propose a possible link between developmental anesthesia neurotoxicity and caspase-dependent cellular responses.

The patient benefit

Better understanding of the time and dose-dependent effects of general anesthetics on the developing brain, particularly in children who have genetic predispositions to conditions such as CHDs, will help researchers understand their role (if any) in behavioral problems often encountered by these patients after surgery.

If found to be a contributing factor, perhaps new therapies to mitigate this caspase activity might be explored to alleviate some of these adverse effects on the developing brain.

What’s next?

The authors hope to stimulate more in-depth research into caspase signaling events, particularly related to how these signaling events change when an anesthetic is introduced. Deeper understanding of how anesthetics impact caspase activation in the developing brain will allow for better assessments of the risk for children who need major surgery early in life.

Children’s National leads the way

Children’s National Hospital leads studies funded by the U.S. Department of Defense to better understand how these other roles of caspases, which until now have not been well-documented, may contribute to brain cell degeneration when activated by prolonged anesthesia and cardiopulmonary bypass during cardiac surgery for congenital heart disease.

Heart anatomy determines outcomes of valve repair for single ventricle hearts after Fontan procedure

human heart

The data shows that the valve repair surgery itself doesn’t increase the likelihood of heart transplant or death. Instead, it is only those with right ventricle dominant heart function who are significantly more likely to have such a negative outcome.

A new study in the Journal of the American College of Cardiology finds the anatomy of the heart is a key predictor of how efforts to repair atrioventricular valve regurgitation — or a leaky heart valve — will impact children with single ventricle heart defects who have undergone a Fontan surgical procedure.

The study uses retrospective data from the largest database of patients who have had the Fontan procedure, the Australia and New Zealand Fontan Registry. The data shows that the valve repair surgery itself doesn’t increase the likelihood of heart transplant or death. Instead, it is only those with right ventricle dominant heart function who are significantly more likely to have such a negative outcome.

It was conducted by cardiac surgeons at Royal Children’s Hospital, including Yves d’Udekem, M.D., Ph.D., who is now chief of cardiac surgery at Children’s National Hospital. Dr. d’Udekem presented the findings at the recent American College of Cardiology Scientific Sessions in Washington, D.C.

What this means

Until now, it was unclear why patients who had undergone a Fontan heart procedure were more likely to need a heart transplant or die after they also underwent surgery to repair atrioventricular valve regurgitation. This type of leaking valve is common in patients who have undergone a Fontan procedure, and it can also be dangerous if left untreated. But because existing data showed poor outcomes following atrioventricular valve repair, it was considered high risk to perform this repair on children with Fontan circulation.

However, this study drilled down into the outcomes of atrioventricular valve repair for these patients and found that it isn’t the surgery that leads to a poor outcome. Instead, it’s a specific anatomic feature — having a dominant right ventricle — that is predictive of the outcome.

Up to now, it was unclear whether surgery should be offered to all patients with a Fontan circulation who had leaky atrioventricular valves. This study shows that things are different for patients with dominant left or dominant right ventricle. For patients with dominant right ventricle, leaving this regurgitation not repaired is much more likely to lead to death and transplantation, and these patients should be operated at the earlier stages of the deficiency of their valves.

The hold-up in the field

One of the biggest challenges to identifying evidence-based best practices for children born with single ventricle heart defects, which are critical congenital heart defects, is the small number of patients at any one institution each year. The Australia and New Zealand Fontan Registry, founded by Dr. d’Udekem and the team at Royal Children’s Hospital, forms one of the world’s longest standing databases of patient information, including outcomes, for this population.

The patient benefit

This data can help doctors and families make the best care decisions possible for children with single ventricle defects by understanding how each child’s unique anatomy may impact how their heart will respond to treatment.

What’s next

Dr. d’Udekem hopes results from this study will improve how doctors strategize and recommend (or not) surgical repair of atrioventricular valve regurgitation. Additionally, the study shows the value of centralized patient registries and data for informing the standard of care. Similar registries across the world may promise to provide even greater insight into the long-term outcomes for patients born with these congenital heart conditions.

CICU telemed command center

New telehealth command center redefines hospital care

CICU telemed command center

The new CICU command center redefines hospital care for children with the riskiest heart conditions.

Children’s National Hospital has opened a new telehealth command center that uses cutting-edge technology to keep continuous watch over the most fragile children with critical heart disease. The new command center, located in the Cardiac Intensive Care Unit (CICU), builds off a care model deployed outside the CICU in 2019, but now offers improved collaborative communication to better help predict and prevent major events, like cardiac arrest.

“The new center acts like an air traffic control tower. It allows our telehealth team to remotely monitor each patient room and alert the bedside team to any abnormal trends,” says Ricardo Munoz, M.D., executive director of the Telemedicine Program and chief of the Division of Critical Care Medicine at Children’s National. “Better communication with the bedside team and easier access to all members of the medical and surgical teams means we can provide the best possible care to these fragile infants.”

In the early stages of recovery after heart surgery, vulnerable patients can regress quickly with few outward physical symptoms. The telehealth virtual surveillance system flags early warning signs that a critically ill infant may suffer a serious adverse event.

The system combines traditional remote monitoring, video surveillance and an artificial intelligence algorithm. New features include:

  • Neuromonitoring: Doctors are developing an adaptable neuromonitoring system that can help signal an impending brain injury before it happens.
  • Echocardiography: A cardiologist, embedded in the new command center, is available to expedite and improve communication within the multidisciplinary team.
  • Real-time audio and video: A telemedicine cart is placed in the room of high-risk patients to allow for rapid communication with a bedside nurse.
  • E-CICU team: A team of CICU nurses and physicians implement a second layer of safety over patient care by doing a systematic review of video feeds from patient rooms, patient monitors, artificial intelligence tools trained to detect dangerous trends, labs and imaging studies.

Since the center’s launch, the system’s virtual surveillance has tracked 8,697 virtual surveillance activities, resulting in:

  • 2,350 non-critical communications
  • 199 critical communications that prevented major adverse events

“Parents of our highest-risk patients are comforted knowing our team of doctors and nurses are watching their child at every moment,” says Dr. Munoz. “We are one of the few pediatric hospitals in the world integrating telemedicine into our CICU. Our goal is to expand our monitoring capabilities both nationally and internationally to improve pediatric heart care.”

Children’s National is a recipient of the Telehealth Accreditation from URAC and is the first pediatric hospital to receive this recognition for its ability to leverage technologies to advance high-quality care that promotes clinical best practices, consumer protections and care continuity between patients and providers.

The Board of Visitors Telehealth Command Center was funded by an Auxiliary Board of Children’s National.

Innovative hypoplastic left heart syndrome treatment offers hope for highest risk children

doctors doing heart surgery

A recently published study in the Journal of Thoracic and Cardiovascular Surgery is a unique report of outcomes for infants treated using a staged surgical approach such as the “hybrid strategy.”

Adopting a staged surgical strategy as the standard of care for medically fragile children with hypoplastic left heart syndrome (HLHS), a critical congenital heart defect, shows promise as an alternative care path for those who may not be ideal candidates for open heart surgery immediately after birth.

A recently published study in the Journal of Thoracic and Cardiovascular Surgery is a unique report of outcomes for infants treated using a staged surgical approach such as the “hybrid strategy.” This initially less-invasive technique involves the placement of small bands on both lung vessels, with or without the placement of a stent on the ductus arteriosus, as the first stage in surgical palliation.

The study reports results from applying this hybrid approach as a bridge to either a delayed Norwood operation or a comprehensive stage II operation. Over 3.5 years, 30 patients with HLHS were considered very high risk for surgery based on their preoperative risk factors such as low birth weight and/or gestational age, shock, and other medical conditions. During that time, the overall survival rate for this group was 70 percent. In the past, using traditional approaches, the survival chance for infants with HLHS and these high-risk factors was extremely limited.

Why it matters

This new surgical strategy gives the baby extra time to grow and allows doctors to collect detailed analysis of potentially treatable accompanying conditions. Furthermore, high-risk babies recover from birth trauma and have the chance to continue developing crucial organs before undergoing more traditional procedures for HLHS that require open-heart surgery with cardiopulmonary bypass. It also allows surgeons to make an individualized risk assessment for which surgical step should be taken next, replacing the historical “one size fits all” operative pathway for HLHS. The traditional operative pathway for HLHS is a series of three open-heart surgical procedures: the traditional Norwood operation, the bidirectional Glenn and the Fontan.

Advancing the standard of care for HLHS patients beyond the current best practice approach to improve outcomes for more newborns has been slow for several reasons, the authors note. One main reason is that performing a hybrid procedure on these particularly fragile infants requires advanced devices and additional technical expertise. As one example, the authors note that until recently, there was no stent available in the appropriate sizes and with the right material properties to work within such a tiny ductus arteriosus. However, case-by-case expanded access approval by the FDA has brought a new stent designed specifically for this use from Europe to the U.S. for the first time.

What they’re saying

“The Norwood operation revolutionized the care of children with HLHS in the 1980s and gave them a chance for survival,” says Can Yerebakan, M.D., senior author of the study and cardiac surgeon at Children’s National who oversees the hybrid program alongside Joshua Kanter, M.D., director of Interventional Cardiology. “This staged decision-making strategy may give the same kind of hope and offers an alternative pathway of care for high-risk patients who would otherwise have a dismal prognosis and extremely low chance   of survival in the newborn period. The success in these cases is, however, based on a multidisciplinary team approach.”

What’s next?

“This strategy not only shows promise for improved short-term survival in high-risk patients, but also boasts the potential to convert some patients to two-chamber circulation instead of one, which our team has done with 100% survival,” says Nicolle Ceneri, M.D., first author of the study and pediatric resident at Children’s National. “As time goes on, we are eager to discover how the use of this approach during such a tenuous period impacts the long-term outcomes for these children and their quality of life.”

Youth with heart defects need a smooth transition to age-appropriate heart care, says AHA

Anitha John

Anitha John, M.D., Ph.D., director of the Washington Adult Congenital Heart Program (WACH) at Children’s National Hospital and incoming chair of the AHA Young Hearts council, served as lead author on the statement, which provides the latest evidence-based best practices for a successful transition from pediatric care to adult care.

The American Heart Association (AHA) issued a scientific statement capturing the best practices for helping children with congenital heart disease successfully transition to adulthood and receive health care tailored to their needs as they continue to age. Ensuring a smooth and supported transition and establishing relationships with these young patients as they grow into adults is key to maintaining their engagement and connection to health care decisions that will improve their long-term health and well-being.

Anitha John, M.D., Ph.D., director of the Washington Adult Congenital Heart Program (WACH) at Children’s National Hospital and incoming chair of the AHA Young Hearts council, served as lead author on the statement, which provides the latest evidence-based best practices for a successful transition from pediatric care to adult care. This work is critical given that today, thanks to the tremendous advances in care and treatment of congenital heart defects in the last two decades, there are more adults living with congenital heart conditions than children.

What this means

The AHA describes a scientific statement as an “expert analysis of current research” that “can inform future care guidelines.” This scientific statement demonstrates the scientific evidence supporting what adult congenital heart specialists have advised for years—that making sure children with congenital heart defects continue to stay engaged in their care and actively seek out health care specialized for them as they grow through adolescence and into adulthood is critical. Keeping that connection plays a pivotal role in their overall quality of life as they age.

Why it matters

Treatments and care for children with congenital heart defects has improved so greatly that, according to the AHA, “most people born with heart defects today, including those with complex heart conditions, survive past childhood and become adults.” But the same care they received as children is not enough to address their needs as adults. Adult-oriented congenital heart care can be the difference between a long and healthy life or continued health challenges and dangerous side effects. Adults with congenital heart conditions should seek out care that serves them best, and it should be accessible to everyone who needs it.

By issuing this updated scientific statement, the AHA is broadcasting the important take home message that adults with congenital heart disease and their care providers need (and should seek) access to an adult-focused program with expertise in caring for the unique challenges they face. Establishing that connection at the transition point from adolescence to adulthood can set the stage for long term engagement and health.

Children’s National Hospital leads the way

As director of the WACH program at Children’s National, Dr. John is one of the nation’s experts in care for adults living with congenital heart disease. She also leads significant patient-centered research efforts focused on understanding barriers to care and other challenges faced by these adult heart patients, including serving as co-principal investigator on one of the largest patient-centered studies of adults living with congenital heart disease, supported by the Patient-Centered Outcomes Research Institute (PCORI). The findings from these studies will help fuel further recommendations and guidelines that will improve the standards of care for these patients.

Ashley Vela Mercedes

Staged surgical hybrid strategy changes outcome for baby born at 28 weeks with HLHS

Ashley Vela MercedesA staged, hybrid cardiac surgical strategy can give fragile infants with hypoplastic left heart syndrome (HLHS) critical time to grow and get stronger. It also gives doctors more time to understand and care for any complicating conditions before necessary open-heart surgery. Doctors at Children’s National Hospital used such a staged approach, called the “hybrid strategy,” to care for Ashley Vela Mercedes, who was born at only 28-weeks-old weighing 1.1 kilos.

Ashley, who is now a smiling and happy 18-month-old, is believed to be the smallest infant born at 28-weeks with HLHS to survive to this age. Though she will need ongoing care and future procedures, her family is grateful for the knowledge and technical expertise of her care team at Children’s National.

The hybrid program at Children’s National is led by Can Yerebakan, M.D., cardiac surgeon, and Joshua Kanter, M.D., director of Interventional Cardiology.

A hypoplastic left heart syndrome miracle

Ashley Vela Mercedes is a happy, smiling 18-month-old. She’s also a true miracle — the smallest baby in the world with HLHS to survive to this age.

Born when her mom was only 28 weeks pregnant, she was 1.1 kilos/2.4 pounds when she arrived — the size of a beanie baby stuffed animal — and her heart was about the size of a grape.

Between her premature birth and her medical issues including her critical HLHS heart condition, her parents, Ana Mercedes and Axel Vela were told that Ashley was unlikely to survive.

The Velas were frustrated, sad and scared. It started to sound like there wasn’t much hope for their tiny baby. They had always dreamed of having a family of their own. Nothing had prepared them for this.

Hope in the hybrid procedure

Their cardiologist, Jennifer Lindsey, M.D., wasn’t ready to give up either. She reached out to the team at Children’s National Hospital to see if Ashley might be considered for a new type of surgery — called a “hybrid procedure.” She hoped that this hybrid procedure might stabilize Ashley’s heart until she could grow strong enough for the open-heart surgeries she would need later.

Hybrid heart procedures blend traditional surgery and a minimally invasive interventional, or catheter-based, procedure. A stent is implanted in the newborn’s ductus arteriosus to hold it open and keep the baby’s blood flowing more efficiently. Usually, the ductus serves as a normal fetal blood vessel that increases blood flow to the mother’s placenta while in utero and closes after the baby is born, when it is not needed.

The hybrid procedure to hold open the ductus isn’t a permanent fix — it just buys the baby extra time to grow and develop before open-heart surgery to start rebuilding the heart in a more sustainable way. They are only considered an option for infants at extremely high risk for open-heart surgery. That’s also why very few congenital heart centers in the world offer them.

The hybrid team at Children’s National is led by Drs. Yerebakan and Kanter have worked together on more hybrid procedures for tiny and fragile infants than most other places. They’ve also worked with the U.S. Food and Drug Administration to safely bring a smaller and more flexible, toothpick-sized stent to the U.S. from Europe that’s made especially for use in the ductus arteriosus of special cases like Ashley.

Record-setting smallest hybrid surgery

Ashley Vela MercedesAccording to Gil Wernovsky, M.D., a cardiac intensive care doctor at Children’s National and Ashley’s Children’s National cardiologist, her birth weight was too low — she weighed 1.1 kilos or 2.4 pounds — for surgery. Her lungs also were not developed enough. She was so small, she lived in the hospital for several more weeks under the care of Dr. Lindsey. Dr. Wernovsky credits the team at Inova Children’s Hospital for providing the support Ashley needed so she could grow and develop to a place where the hybrid procedure was possible.

When she reached 1.7 kilos or 3.7 pounds, she was transported to the Cardiac Intensive Care Unit at Children’s National Hospital for her first procedure, the hybrid. At the time, she was officially the smallest baby to have a hybrid procedure at Children’s National. After the surgery, the Children’s National CICU was Ashley’s home for almost her entire first year of life.

“Landing here at Children’s was a blessing because we thought she was going to die. What has happened here is a miracle,” said Ana Mercedes. “I would like to tell Dr. Yerebakan and Dr. d’Udekem (the chief of Cardiac Surgery at Children’s National) that what they have done with my daughter is incredible, and I will never be able to fully repay them for their efforts.”

Over the next 11 months in the hospital, Ashley had many surgeries and catheterizations, countless other medical procedures and tests, and many, many ups and downs, including some very scary times when she required extracorporeal membrane oxygenation (ECMO) for critical life support.

Celebrating and thriving at home

Ashley Vela MercedesIn July 2021, Ashley went home for the first time in her life. She hasn’t needed to be hospitalized since her discharge. She’s monitored jointly by Dr. Lindsey and the Children’s National single ventricle monitoring program. That program stays in touch with families virtually three times each week. Her care team keeps up with her growth and development through telehealth. Ana Mercedes shares videos and photos of Ashley as part of her routine updates to the clinical team.

She still needs some medical support at home and will likely need additional medical interventions down the road, but for the time being, she is a more independent, happier and thriving little girl.

And she’s a miracle — she is the smallest baby in the world born with HLHS at such a small size and weight to survive to this age.

Ana Mercedes dreams of taking Ashley to the Dominican Republic one day, so they can enjoy the famous beaches and Ashley can be introduced to her heritage since that’s where Ana Mercedes is from.

“We are overall doing well. We have received support from our family and employers,” said Ana Mercedes. “We are extremely grateful to everyone who has given us a hand during this challenging time.”

The last year has been a roller coaster, but Ashley has made incredible progress and exceeded everyone’s expectations. Dr. Wernovsky notes, “Last year at Christmas time, this little girl was on her fourth catheter procedure and had been in intensive care for her entire life. One year later, she’s at home with her family and celebrating — that’s quite the Christmas miracle.”

Children’s National leads patient-centered study of adult congenital heart disease

doctor listening to patients heart

The team will work with the 14 research institutions across the United States to collect data and then examine rates of complications or associated illnesses, as well as how adult patients have accessed health care throughout their lives.

Investigators at Children’s National Hospital and the Louisiana Public Health Institute are leading a $4.9 million research effort to study how gaps in health care affect the health and well-being of adults with congenital heart disease (CHD), supported by the Patient-Centered Outcomes Research Institute (PCORI).

The research is led by Anitha John, M.D., Ph.D., medical director of the Washington Adult Congenital Heart Program at Children’s National Hospital and Thomas Carton, Ph.D., chief data officer at the Louisiana Public Health Institute, as well as two patient co-investigators, Ruth Phillippi and Scott Leezer. The study leads also include representatives from the Adult Congenital Heart Association and Anu Agarwal, M.D., who represents the University of California – San Francisco (UCSF).

“With the increasing number of adult patients with CHD, it is important for us to understand how current recommended practices influence patient outcomes,” says Dr. John. “This project will guide us on how to best care for our patients, not just through childhood, but across their entire lifespans. Most importantly, this project will involve direct outreach to patients, incorporating patient reported outcomes as a measure of long-term outcomes.”

Together, the team will work with the 14 research institutions across the United States to collect data and then examine rates of complications or associated illnesses, as well as how adult patients have accessed health care throughout their lives. The findings may help predict which patients are at greater risk of falling out of routine health care, and when these gaps in care are likely to occur across a patient’s lifespan. The study will also correlate findings with how patients are actually feeling in their everyday lives.

The 14 participating institutions are:

  • Ochsner Health
  • Children’s Hospital of Philadelphia
  • Icahn School of Medicine at Mount Sinai
  • University of California – San Francisco
  • Nationwide Children’s Hospital
  • Duke University Health System
  • NYU Grossman School of Medicine
  • Nicklaus Children’s Hospital
  • Children’s Hospital Colorado
  • University of Miami
  • Columbia University Irving Medical Center
  • Cincinnati Children’s Hospital Medical Center
  • Weill Cornell Medical College
  • University of Florida

“This unprecedented look at the health of adults living with congenital heart disease allows us to get a full spectrum view by combining clinical data with patient-reported health data,” says Dr. Carton.

The first patient-powered registry for adults with CHD — the Congenital Heart Initiative (CHI) is a key component of this research. Launched with seed funding from Children’s National and the Heart Research Alliance at UCSF, the CHI is led by Dr. John and her team at Children’s National in addition to a broad multi-stakeholder advisory board, including patients. The CHI was co-developed with input from patients, clinicians and researchers and continues to involve these voices in the advancement of the registry. Patients who are recruited for this research will participate via enrollment in the registry, which will allow researchers to ask patients directly about health, wellness and any specific barriers to care. Learn more about CHI’s progress in their first annual report.

“Patients, like myself, are charting a new course and we desire answers to significant questions, as do our providers, about impact of lifelong specialized care, along with improved understanding of the quality-of-life patients experience,” says Leezer. “This project represents a huge step forward towards obtaining answers for the adult CHD community.”

The study also draws on the vast health data resources of PCORnet®, the National Patient-Centered Clinical Research Institute, to conduct this study more efficiently. With health records for 66 million patients available for observational studies, the PCORI-funded PCORnet provides vast scale to power research on conditions affecting even small numbers of people.

“We are confident that this research will yield critical learnings that will empower the community, align resources and spur future innovation to better meet the specialized care needs of this emerging population,” says Mark Roeder, president and chief executive officer for the Adult Congenital Heart Association.

PCORI is an independent, nonprofit organization authorized by Congress in 2010 to fund research that will provide patients, their caregivers and clinicians and other health care decision makers with the evidence-based information needed to make better-informed health care choices.

Pediatric medical device competition takes aim at congenital heart disease

NCC-PDI logo

Consistent with its mission of addressing the most pressing pediatric device needs, this year’s competition focused on innovations in electrophysiology devices that monitor and treat congenital heart disease (CHD) and arrhythmias in pediatric patients.

The National Capital Consortium for Pediatric Device Innovation (NCC-PDI) announces five awardees chosen in its prestigious annual “Make Your Medical Device Pitch for Kids!” competition to share $150,000 in grant funding from the U.S. Food and Drug Administration (FDA) to support the advancement of pediatric medical devices. In an unprecedented decision, the competition judges determined that all five finalists were deserving of a grant award and recognition for the potential patient benefit and commercial viability of their innovations.

Consistent with its mission of addressing the most pressing pediatric device needs, this year’s competition, conducted by NCC-PDI partner MedTech Innovator, focused on innovations in electrophysiology devices that monitor and treat congenital heart disease (CHD) and arrhythmias in pediatric patients. The virtual pediatric pitch event was part of the 9th Annual Symposium on Pediatric Device Innovation.

This year’s pediatric device innovation awardees are:

  • PeriCor – The Children’s Hospital at Montefiore – New York, NY, and Children’s National Hospital – PeriTorq, a catheter grip tool for use during pediatric cardiac interventional procedures;
  • Inkspace Imaging – Pleasanton, CA – a pediatric cardiac and vascular MRI coil;
  • Karios Technologies – Charlottesville, VA – Tissue Shield, a technology to prevent scar tissue formation (adhesions) on the heart after surgery;
  • Sibel – Niles, IL – ANNE One, ICU-grade wireless sensors for cardiopulmonary monitoring in neonates with congenital heart defects;
  • Starlight Cardiovascular – San Diego, CA – Project Lifeline, a less-invasive way to maintain sufficient circulation in newborns with ductal-dependent circulation that increases safety, procedural success and ease of use.

Congenital heart disease (CHD) affects six out of 1,000 babies born in the U.S. each year and is often complicated by arrhythmias, a condition where the heart beats too rapidly, too slowly or irregularly due to a misfiring of the body’s electrical impulses. While the last decade brought great advances in technologies that improve the care of adult arrhythmias, pediatric patients have been left behind, with only five devices approved for use in children in the same period. As a result, pediatric specialists are often using off-label or improvised devices to treat pediatric arrhythmias, including in the smallest newborns.

“Recognizing this unmet need, NCC-PDI opened the challenge earlier this year to select companies to enter MedTech Innovator’s pediatric accelerator program, made possible by NCC-PDI. The five companies have immensely benefited from the accelerator program and are well-positioned to compete for funding. They have the potential to advance pediatric health and provide a greater standard of care for children living with CHD,” says Kolaleh Eskandanian, Ph.D., M.B.A, P.M.P, vice president and chief innovation officer at Children’s National Hospital and principal investigator of NCC-PDI. “For too long, the unique needs of children have been overlooked in pediatric device development. Thanks to the support of the FDA, we are able to build our challenge competitions around the direst unmet needs, which are determined through a thorough needs assessment and market analysis conducted to inform each request for proposal. The funding incentivizes pediatric innovation and helps more companies navigate the path to commercialization.”

NCC-PDI is one of five consortia in the FDA’s Pediatric Device Consortia Grant Program created to support the development and commercialization of medical devices for children, which lags significantly behind the progress of adult medical devices. NCC-PDI is led by the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National Hospital and the A. James Clark School of Engineering at the University of Maryland, with support from partners MedTech Innovator,  BioHealth Innovation and design firm Archimedic.

A pediatric accelerator program, powered by MedTech Innovator, is the consortium’s latest addition to a network of resources and experts that NCC-PDI provides in support of pediatric innovators. All five of this year’s competition finalists had an opportunity to participate in the year-long accelerator program.

Eskandanian adds that supporting the progress of pediatric innovators is a key focus of the new Children’s National Research & Innovation Campus, a one-of-its-kind ecosystem that drives discoveries that save and improve the lives of children. On a nearly 12-acre portion of the former, historic Walter Reed Army Medical Center in Northwest Washington, D.C., Children’s National has combined its strengths with those of public and private partners, including industry, universities, federal agencies, start-up companies and academic medical centers, the campus provides a rich environment of public and private partners which, like the NCC-PDI network, will help bolster pediatric innovation and commercialization.

Penicillin slows impacts of rheumatic heart disease in Ugandan children

Dr. Sable performing an echocardiogram in Uganda

“We know from previous studies that though it is not always well-documented, sub-Saharan Africa continues to have some of the highest numbers of people with rheumatic heart disease and the highest numbers of people dying from it,” said Craig Sable, M.D., associate chief of Cardiology at Children’s National Hospital and co-senior author of the study. “This study is the first large-scale clinical trial to show that early detection coupled with prophylactic treatment of penicillin is feasible and can prevent rheumatic heart disease from progressing and causing further damage to a child’s heart.”

Penicillin, a widely available and affordable antibiotic, may be one key to turning the tide on the deadly impacts of rheumatic heart disease (RHD) for children in developing nations. This according to the new findings of a large-scale, randomized controlled trial completed in Uganda and published in the New England Journal of Medicine.

The most devastating feature of RHD is severe heart valve damage that is caused by rheumatic fever — a condition that results from the body’s immune system trying to fight poorly treated, repeat infections from streptococcus bacteria, also known as strep throat. Though widely eradicated in nations such as the United States due to the swift detection and treatment of strep throat, rheumatic fever remains prevalent in developing countries including those in sub-Saharan Africa. Current estimates are that 40.5 million people worldwide live with rheumatic heart disease, and that it kills 306,000 people every year. Most of those affected are children, adolescents and young adults under age 25.

“We know from previous studies that though it is not always well-documented, sub-Saharan Africa continues to have some of the highest numbers of people with rheumatic heart disease and the highest numbers of people dying from it,” said Craig Sable, M.D., associate chief of Cardiology at Children’s National Hospital and co-senior author of the study. “This study is the first large-scale clinical trial to show that early detection coupled with prophylactic treatment of penicillin is feasible and can prevent rheumatic heart disease from progressing and causing further damage to a child’s heart.”

The study was led by an international panel of pediatric cardiac experts from institutions including Children’s National, Cincinnati Children’s Medical Center, the Uganda Heart Institute and Murdoch Children’s Research Institute in Melbourne, Australia.

“Our study found a cheap and easily available penicillin can prevent progression of latent rheumatic heart disease into more severe, irreversible valve damage that is commonly seen in our hospitals with little or no access to valve surgery,” said co-lead author Emmy Okello, M.D., chief of Cardiology at the Uganda Heart Institute.

To Andrea Beaton, M.D., associate professor of Cardiology at Cincinnati Children’s and co-lead author, this is the first contemporary randomized controlled trial in rheumatic heart disease. “The results are incredibly important on their own, but also demonstrate that high-quality clinical trials are feasible to address this neglected cardiovascular disease,” she said.

Beaton et al. named the trial Gwoko Adunu pa Lutino (GOAL), which means “protect the heart of a child.” The study enrolled 818 Ugandan children and adolescents ages 5 to 17 years old who were diagnosed with latent rheumatic heart disease to see if an injection of penicillin was effective at preventing their heart condition from worsening.

“There are many challenges with recruitment and retention of trial participants in areas like our study region in Uganda,” said Dr. Sable. “But it is critical to work together and overcome barriers, because we must study these treatments in the people most affected by the condition to understand how they, and others like them, may benefit from the findings.”

Of the 799 participants who completed the trial, the group receiving a prophylactic injection of penicillin (399 volunteers) had three participants show evidence of worsened rheumatic heart disease on repeat echocardiogram after two years. In contrast, 33 of the 400 volunteers in the control group, who received no treatment, showed similar progression on echocardiogram results.

Professor Andrew Steer, who is theme director of Infection and Immunity at Murdoch Children’s Research Institute in Melbourne and who served as senior author of the study, said screening for latent rheumatic heart disease was critical to stop progression because heart valve damage was largely untreatable. “Most patients are diagnosed when the disease is advanced and complications have already developed. If patients can be identified early, there is an opportunity for intervention and improved health outcomes.”
