Pediatric Cardiology Research

A nurse and a teenage boy look at a monitor together

When your child is treated at the Blalock-Taussig-Thomas Pediatric and Congenital Heart Center, the most modern technology and leading-edge research go into every aspect of his or her care plan.

Your child’s doctor is part of a dedicated team that includes researchers from around the world who are advancing and developing new concepts in predicting, diagnosing and treating pediatric cardiology conditions.

Johns Hopkins’ unique atmosphere encourages collaboration among laboratory investigators and doctors treating patients. Our patients benefit from the rich knowledge resulting from this robust exchange of ideas.

Current Research

Laboratories and Areas of Study

Our laboratories include physicians and scientists dedicated to improving pediatric cardiac care and the health and quality of life for children with heart disease. The laboratories use a range of approaches: Some study mouse models of disease; others apply data, basic science and clinical information gathered from treating patients.

In addition, unique, collaborative projects with large technology firms connect our team with the scientific expertise within these companies. Together, we can work on innovative solutions for children with heart disease.

  • Anne Murphy Laboratory

    Anne Murphy’s laboratory studies cardiomyopathy and key proteins that are part of the contractile ap...paratus. The team is looking at how modifications to these proteins might affect various diseases and heart failure. She also investigates the role of genetics in pediatric heart failure associated with acute heart failure, which is sometimes attributed to myocarditis. Her laboratory has received grants from the American Heart Association, the National Institutes of Health and the Children’s Cardiomyopathy Foundation. Murphy received the Rowe Award for Cardiology Research from the Society for Pediatric Research and other awards. Her research on the molecular basis of myocardial stunning was named one of the top 10 research achievements for 1999 by the American Heart Association. view more

  • Ari Cedars Laboratory

    Ari Cedars, M.D., and his team have three primary research goals. First, the Cedars Lab is intereste...d in patient-centered outcomes in congenital heart disease, which they investigate using a digital tracking system to record participants’ symptoms and quality of life. Second, the Cedars Lab investigates outcomes with mechanical circulatory support and transplant in congenital heart disease, with a focus on those with end-stage heart disease and a Fontan circulation. Third, the Cedars Lab is interested in the biological mechanisms underlying circulatory deterioration and end-organ dysfunction in patients with a Fontan circulation. view more

    Among the hundreds of predictive models developed for cardiovascular disease, less than one-tenth of... 1% actually end up routinely used in clinical practice. CV-Ai2 uses data from clinical practice and analytic intelligence to solve clinical problems and create solutions that can be applied in real-world patient care. view more

  • Obesity Hypertension Clinic: Reversing the Negative Cardiovascular Effects of Weight (ReNEW)

    Hypertension in children is a major cause of disease, including early onset heart disease. Up to 25%... of children who are overweight or obese have hypertension (high blood pressure), and children with obesity are at greater risk for having other cardiovascular disease risk factors such as high cholesterol and diabetes. The ReNEW Clinic at The Johns Hopkins University provides an innovative multidisciplinary approach to the evaluation and treatment of obesity-related hypertension to help prevent and treat cardiovascular disease. This clinic is designed for children with elevated blood pressure (prehypertension and hypertension) and a BMI at or above the 85th percentile. Many children in this clinic are enrolled in a longitudinal registry to help researchers learn how to better care for children with multiple risk factors for heart disease.

    Beyond the Stethoscope: Artificial Intelligence Can Help Diagnose Heart Murmurs

    Dr. Thompson counsels a patient during a virtual appointment

    Reid Thompson’s research is evaluating an artificial intelligence (AI) algorithm that can detect abnormal heart murmurs by using a large database of heart sound recordings.

    This “virtual clinical trial” technology was developed by Thompson to test a heart murmur detection algorithm created in Austria by a team of engineers using heart sounds recorded in Europe and Canada. The heart sound database used in this research was created by Johns Hopkins through a collaboration between Johns Hopkins Children’s Center and the Johns Hopkins University Applied Physics Laboratory. It houses recordings from over 1,200 patients with many different kinds of heart disease, according to Shelby Kutty, director of the Blalock-Taussig-Thomas Pediatric and Congenital Heart Center.

    This study shows that the algorithm can distinguish abnormal from normal heart sounds with high accuracy. In this way, the technology can help clinicians avoid unnecessary testing of “innocent” heart murmurs, while helping them spot serious heart disease, especially in very young infants.

    “This study helps to show that AI-assisted auscultation [listening to heart sounds with a stethoscope] may breathe new life into this age-old icon of medicine,” Kutty says. Thompson is now combining algorithm-based screening with telemedicine to study new ways of distinguishing pathologic from innocent heart murmurs that he hopes may lead to more appropriate use of echocardiography.
