Herma Heart Institute programmatic grants

Cord Blood Component of the Precision Medicine Program — Joy Lincoln, PhD

The Cord Blood Component offers pregnant parents the option to save their newborn’s otherwise discarded umbilical material, so that it is available if and when needed for their child’s medical treatments for a diagnosis such as cancer, blood disorder, immune disorder, metabolic disorder and in the future, congenital heart disease (CHD). This year, the HHI implemented and refined a pipeline at Froedtert Hospital Maternal Fetal Care in collaboration with Cord Blood Registry, Inc. Umbilical material of 73 newborns cared for at Children’s Wisconsin is now stored in an accredited laboratory, and our research team envisions many future treatments, such as growing the child’s own cells into patches for use in heart or valve surgery. 

ACTION database Epic integration — Robert Niebler, MD

Creating documentation tools that transform the day-to-day work of the clinician to discrete data fields collected by a database has the potential to increase the efficiency and accuracy of this data transfer. These grant funds were focused on the Advanced Cardiac Therapies Improving Outcomes Network (ACTION) database data transfer and transforming it from the current manual process by an experienced clinician to an automated transfer of information that is documented by the clinician in real time and transmitted to the database at regular intervals. The project will help improve data access, transfer and visibility within Epic to improve the care of our patients across the HHI. 

Herma Heart Institute research grants

Spatial transcriptomic profiling of bicuspid aortic valves — Joy Lincoln, PhD 

In bicuspid aortic valve (BAV), up to 50 percent of young adult patients experience accelerated development of calcification and aortic stenosis. Despite this, clinical management is limited to periodic surveillance of valve dysfunction, and intervention is recommended only when the valve becomes stenotic. Children affected by BAV would benefit from a comprehensive risk profile assessment before calcification to develop more effective clinical management strategies. This study focuses on integrating computational modeling with spatial transcriptomic technology in BAV models to correlate changes in biomechanics with gene expression.

*Explore heart muscle cell division and its impact on heart repair — Lu Han, PhD 

Adult ischemic heart injury causes significant loss of cardiomyocytes (CMs), leading to heart failure over time. Developing methods to therapeutically stimulate cardiomyogenesis promises to improve the lives and survival of these patients. However, cardiomyogenesis in the adult heart is challenging due to the limited proliferative capacity of adult CMs. 

The team’s goal is to elucidate the molecular and cellular mechanisms that regulate CM mitosis during embryogenesis and early postnatal maturation to ultimately achieve cardiac regeneration after ischemic injury.

*Evaluating the efficacy of human recombinant dornase alfa on cell-free DNA — Justinn Tanem, MD

This is part of the lab’s broader work to document and potentially reduce cell-free DNA (cfDNA) levels during pediatric cardiac surgery with cardiopulmonary bypass (CPB). The idea of intentionally decreasing cfDNA levels evolved from the group’s clinical study that demonstrated high cfDNA levels are significantly associated with poor outcomes. These include cardiac arrest, need for ECMO support, prolonged hospital stays after surgery and death. The overall question is: if we lower cfDNA levels, can negative outcomes be mitigated or avoided altogether? To answer that question, this study takes the important first step, using a laboratory model of CPB surgery to ascertain if human recombinant dornase alfa lowers cfDNA levels in human blood.

*Funding for this research was provided by Children’s Wisconsin, the Medical College of Wisconsin, Advancing a Healthier Wisconsin Endowment and the Herma Family Foundation.

Investigation of pulmonary arteriovenous malformations in single ventricle congenital heart disease — Andrew Spearman, MD 

The pathophysiology of single ventricle pulmonary arteriovenous malformations (PAVMs) is unknown, but Dr. Spearman hypothesizes that infiltrating immune cells and subpopulations of endothelial cells drive it. This work aims to investigate the pathogenesis of single ventricle PAVMs mechanistically.

The role of MYH6 and NPR3 variants in coarctation of the aorta — Aoy Tomita-Mitchell, PhD

The etiology of coarctation of the aorta (CoA) is unknown. The Mitchell Lab studies the impact on heart development of variants of the gene called MYH6. To date, their findings suggest having a MYH6 variant hinders normal development of the left ventricular outflow tract, which may contribute to CoA. This study examines rare, predicted damaging variants in MYH6 in patients with CoA. A second aim of this grant is to extend previous work with the LaDisa Lab and explore a second gene called NPRC (NPR3), to further aid understanding into long-term complications associated with CoA

Cardiac precision medicine team drives innovation

A targeted approach means brighter futures for kids with congenital heart disease 

Precision medicine has been gaining wider adoption for its potential to deliver medical care that is optimized for each individual person. This level of personalization requires a multidisciplinary approach that considers a patient’s genetics, environment, health history and lifestyle. 

Cardiac precision medicine at the Herma Heart Institute applies these concepts to improve the prevention, diagnosis and treatment of congenital heart disease (CHD) in babies, teens and adults. It is anchored by an invested team of medical professionals and researchers, including cardiologists, physician assistants, anesthesiologists, surgical teams and technical teams. They all work in concert with patient families to determine the best course of action for a patient.

This team approach has facilitated some recent breakthroughs in cardiac precision medicine.

Breakthrough 1: Hypoplastic left heart syndrome

A research team, including Aoy Tomita-Mitchell, PhD, and Michael E. Mitchell, MD, has been studying how variants in the a-myosin heavy chain (MYH6) gene are implicated in hypoplastic left heart syndrome and other congenital heart defects. 

“We have a hardworking team focusing on this because it is a very important problem, and this genetic defect seems to be causative of hypoplastic left heart syndrome in over 10 percent of cases,” said Dr. Mitchell, surgical director of the Herma Heart Institute at Children’s Wisconsin. “This is a discovery that came from our institution: MYH6 variants are responsible for more cases of HLHS than any other known genetic disorder. In addition, they are associated with significantly worse clinical outcomes. We’ve come to understand more about the mechanism of the variant and how we can use medications that are targeted to treat heart failure in patients with this variant.”

This knowledge has led to personalized treatment plans that will help many patients with hypoplastic left heart syndrome live into adulthood instead of passing in infancy. 

Breakthrough 2: Cord Blood Program

Collecting umbilical material (cord blood and tissue) can be extremely valuable because it can be used in two different ways: research and potential therapy. 

“Contained in cord blood are stem cells,” said Dr. Mitchell. “And what we hope to achieve from drawing cord blood is to generate different cell types, including those that make up the heart. We hope to then create biomaterials from the patient’s own cells that can be used for surgical repair of patients with CHD.”

Identifying pregnancies involving a fetus with hypoplastic left heart syndrome or other CHDs and getting the families to sign up for the Cord Blood Program allows for the collection of cord blood at the timeof delivery.

“There are many situations where you see cord blood thrown away because people aren’t aware of the difference it can make or aren’t informed about an opportunity they might have to save it,” said Joy Lincoln, PhD, director of cardiovascular research at the Herma Heart Institute. “In our case, we have partnered and collaborated with the largest national stem cell banking company, the Cord Blood Registry. They have a clinical-grade storage facility, so after families join our program, we can store their samples at no cost, in preparation for clinical application.”

The Cord Blood Program was started in 2020, and in 2022, it collected 58 samples from patients’ umbilical-derived cord tissue and cord blood. From the samples, Dr. Lincoln and her team have been isolating stem cell populations and using them in the lab to better understand the cause of CHD.

“The goal is to use patients’ own cells extracted from umbilical material to develop surgical material,” said Dr. Lincoln. “We can use those cells to develop a tissue that will be implanted back into the child at the time of their surgical intervention. If they ever need corrective surgery, we have the potential to differentiate the stem cells derived from the umbilical material into necessary cardiac cells.”

Making breakthroughs possible

Without sponsors, these and other programs wouldn’t be possible. 

“The Herma family and so many other gracious donors have been so crucial to the strides we’ve made,” said Dr. Lincoln. “The community is generous and rallies behind health in a way that is rare. We couldn’t do it without them.” 

Children’s Wisconsin also looks to federal programs, national organizations and industry partnerships for support for important initiatives like the Cord Blood Program and cardiac precision medicine. “There is a great deal of hope, but it will take the support and generosity of many to get to where we want to be,” said Dr. Lincoln.

Preparing the next generation of researchers

Spotlight on educational research program

Physician-scientists and basic and translational scientists play critical roles in advancing medicine and the search for better cures and treatments for congenital heart disease (CHD) patients. Unfortunately, many institutions face challenges with providing accessible and equitable research opportunities to trainees due to financial insecurities and high competition for faculty openings.

At the Herma Heart Institute (HHI), we have made it a priority to instill a culture of discovery in the lab and clinic by providing robust training programs for individuals considering an academic career in research. Our goal is to ensure that trainees can see and appreciate the impact their research contributions have on the advancement of the medical field and improving health in the community. 

Through partnerships with the Medical College of Wisconsin, Children’s Wisconsin Foundation, Advancing a Healthier Wisconsin, the National Institutes of Health (NIH) and the American Heart Association, the HHI has provided paid opportunities in pediatric cardiovascular medicine research for more than 100 trainees in just five years. Trainees include high school, undergraduate, medical and graduate school students, residents, and fellows-in-training from diverse backgrounds.

These programs have enhanced the critical thinking and technical skills required to perform high-quality and impactful research related to CHD while engendering lifelong mentoring relationships. 

Andrew Kim, MD, PhD, is one trainee who has benefited from this pipeline. The third-year Pediatrics resident at the Medical College of Wisconsin joined Dr. Lincoln’s lab as part of an NIH-funded physician-scientist immersion program, led by Michael E. Widlansky, MD, MPH, and Mary Eapen, MRCPI, MS, MBBS. This award has provided a unique opportunity for Dr. Kim to pursue his passion as a clinician-investigator with significant research time during his clinical residency. During this two-year, research-focused pathway, Dr. Kim is exploring effective therapeutics in the treatment of the rare disorder of neonatal Marfan syndrome that leads to premature lethality due to complex cardiovascular complications. 

“The HHI views the training of future physician-scientists as an important part of its mission,” said Dr. Kim. “By being able to integrate clinical care with laboratory research during my residency training, I have been able to draw from patient experiences to generate important research questions as well as evaluate scientific studies from a clinical perspective.” 

To advance the field of pediatric cardiology and recruit and retain outstanding researchers with an interest in research careers, it is critical that education pipelines like those offered by the HHI support Dr. Kim and others like him, who are the next generation of medical researchers.

Clinical Spotlight

Long-term success

Spotlight on heart failure and heart transplant program  

Steven J. Kindel, MD, program director of the Pediatric Heart Failure and Heart Transplant Program at Children’s Wisconsin and associate professor of pediatrics at the Medical College of Wisconsin, understands that success in these cardiology programs means going beyond the intensive medical and surgical procedures to support patients and families in a holistic manner.

“It’s my job to help them get to where they want to be,” said Dr. Kindel. “We don’t want these kids in a hospital. We’re focused on treatments and approaches to normalize their lives as much as possible, so they can grow, develop and get back to being kids again.” 

Launched in 2015, the Pediatric Heart Failure Program takes a multidisciplinary approach to utilize the expertise of the Herma Heart Institute (HHI) and other Children’s Wisconsin programs. We strive to provide personalized treatment plans for each patient that can include mental and behavioral health care, art and music therapy and working with our child life team and social workers to help patients and families cope with the mental and social aspects of their condition, not just the physical components.

As an example, Dr. Kindel pointed to the case of Jackson Radandt, who was diagnosed with hypoplastic left heart syndrome (HLHS) in 2001. This serious condition affects 1 out of every 3,841 babies born in the United States and requires surgical intervention for survival. About 50 percent of children with HLHS experience heart failure by age 15, and Jackson was no exception. When he had heart failure at age 11, he became the youngest patient in the country with a prior Fontan procedure to receive a ventricular assist device as a bridge to transplant.

His device implant came with immediate success, allowing him to be at home with family and even in school before he received a heart transplant at age 12. After the transplant, Jackson was discharged after only 11 days and through his recovery, was able to engage in a level of physical activity he hadn’t before, joining his school basketball team

While heart transplantation is a journey that extends into adulthood, Dr. Kindel and his Pediatric Heart Transplant Program team strive to reduce limitations for their patients as much as possible.

“One of our big goals for our patients and their families is to decrease the medical intensity and work toward lowering the number of visits and tests — especially invasive testing — so that we’re not forcing patients to have as many procedures or time in the hospital,” he said.

Today, Jackson is thriving as an adult. He went to Marquette University to double-major in biomedical sciences and political science and is currently working in Washington, D.C., with the U.S. Senate.

“You don’t do this job just to get to a transplant,” said Dr. Kindel. “You do this for the graduations, weddings, etc. That’s the part we are striving to provide all our patients, and the stuff that makes all the hard work worth it.”

Bringing care closer to home

Spotlight on new Children’s Wisconsin Appleton Clinic

In 2023, Children’s Wisconsin expanded its cardiology services and offerings in Northeast and Central Wisconsin with the opening of the new Children’s Wisconsin Appleton Clinic. The new clinic makes cardiac care more accessible and closer to home for patients and families, reducing the need to travel outside of the region for care.

With more than 50,000 square feet of clinical space, the Appleton Clinic brings together more than 20 pediatric specialties, including fetal, pediatric and adult congenital cardiology. The clinic features five cardiology exam rooms, three echocardiogram labs and a stress test lab, and has ten rotating cardiologists and advanced practice providers on staff. The Appleton Clinic is the only Children’s Wisconsin regional clinic that can provide full comprehensive cardiopulmonary exercise testing for patients with congenital heart disease as well as new patients needing cardiac clearance. 

The Appleton Clinic also supports Connected for Kids, a pediatric joint venture with Bellin Health and ThedaCare. Together, the three health systems are working to make a meaningful impact on the lives of children and adolescents by connecting families to the highest level of pediatric health and wellness services.

Where heart care comes full circle

Spotlight on adult congenital heart disease program and pregnancy 

Since its inception in 2004, the Herma Heart Institute (HHI) has been growing and developing one of the nation’s leading adult congenital heart disease (ACHD) programs, and the largest in Wisconsin. Scott B. Cohen, MD, serves as the director of this program, which works in conjunction with Froedtert Hospital and the Medical College of Wisconsin health networks.

With training in pediatric and adult medicine, in addition to advanced training in adult congenital cardiology, Dr. Cohen and the ACHD team are uniquely qualified to care for patients through every age and stage of life, including pregnancy.

“We know that with pregnancy, there’s an increased workload and stress on a woman’s heart,” said Dr. Cohen. “There are types of heart disease that can put that woman at a higher risk of having heart-related adverse events, like heart failure or arrhythmias. We also know that women with ACHD have improved pregnancy and birth outcomes when they are cared for by a team of multidisciplinary specialists who understand their unique care and treatment.” 

The ACHD program is part of the Heart Disease in Pregnancy Clinic at Froedtert Hospital, where women with congenital heart disease get individualized care from a team that includes ACHD specialists, general cardiologists, maternal fetal medicine specialists and OB/anesthesiologists. The ACHD program also partners with one of the nation’s top fetal cardiac programs, the Children’s Wisconsin Fetal Concerns Center.

An important aspect of treating ACHD during pregnancy is assessing the fetus. The risk of a fetus developing congenital heart disease increases to approximately 6 to 7 percent when the mother also has congenital heart disease. 

Women in the Children’s Wisconsin ACHD program who become pregnant undergo a specialized fetal echocardiogram to assess their unborn baby’s heart structure, rhythm and function. “If a developing baby has been diagnosed with congenital heart disease, then the mother and baby are followed closely by our fetal heart program specialists to determine a care plan for pregnancy, labor and delivery, and the postpartum period,” said Dr. Cohen. 

The HHI is dedicated to providing the best possible care to pregnant ACHD patients and their developing baby through pregnancy, birth and beyond.

Making strides in clinical care management 

Herma Heart Institute takes a collaborative approach to improve patient outcomes  

Angelia Espinal, director of clinical outcomes for the Herma Heart Institute, views Children’s Wisconsin as an innovator. And she knows a leading institution can’t innovate without a sustainable foundation and focus on quality and outcomes improvement.

Such focus “requires the Herma Heart Institute to maintain real-time, continuous evaluation of clinical outcomes and drive improvement efforts through quality science” said Espinal. “We must also remain adaptive, particularly as things evolve in terms of new technologies or clinical advancements.” The Quality, Outcomes and Research (QOR) team at the Herma Heart Institute supports clinical teams, operational leaders and researchers in the collaborative effort toward improving whole health across the continuum of care.  

Collaborating for quality improvement

According to David Saudek, MD, associate professor of pediatrics and associate medical director for the Herma Heart Institute, a key change in the field of pediatric cardiology and general heart surgery in the last decade is a more collaborative approach across centers. The Herma Heart Institute works with several national collaboratives, including the National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC) and the Pediatric Cardiac Critical Care Consortium (PC4). “Each of these collaboratives is a group of cardiac care centers that share outcome data and practices so that we can work together to improve care,” said Dr. Saudek.

Espinal pointed to Hearts to Home as a quality-focused national initiative, coordinated by the Pediatric Acute Care Cardiology Collaborative (PAC3). This initiative promotes “a system goal of discharging patients within 120 minutes of medical readiness and removing barriers that would prevent them from getting discharged in a timely fashion,” she said. 

Diving into outcomes

The Herma Heart Institute has built data applications to readily access congenital heart surgical outcomes data, echocardiographic data and Kaplan-Meier survival curves for long-term outcome analysis. These applications allow providers to quickly access local outcomes data to help guide clinical decisions. Additionally, the HHI internal outcomes, combined with national collaborative data, allow clinical care teams to compare outcomes with other centers, analyze areas where there could be improvement and recognize where we are excelling.

A relentless focus on quality improvement initiatives and evaluating outcomes ultimately drives the most important result: providing the best care for patients.
