Seeing her patients’ lives improve is what drives Catherine Avitabile, MD, both in her clinical practice and in her research.

“I enjoy taking care of children with complex cardiopulmonary diseases and their families. I want to advance care and help children with congenital heart disease and pulmonary hypertension live the most normal, full lives possible,” Dr. Avitabile says.

Dr. Avitabile treats patients with a variety of cardiopulmonary conditions, including pulmonary hypertension, pulmonary hypoplasia, bronchopulmonary dysplasia, and thoracic insufficiency syndrome — all serious problems that have, in the past, limited the ability of children with these conditions to participate in physically demanding activities.

Dr. Avitabile relishes helping her patients and their families overcome obstacles to achieve happy, healthy, active childhoods.

As a researcher, Dr. Avitabile has made contributions to the general understanding of the physiology of some of these conditions through imaging procedures, as well as investigating new treatments.

“I am active in pulmonary hypertension research in the Divisions of Cardiology and Neonatology and the Department of Surgery, as well as within the multicenter Pediatric Pulmonary Hypertension Network,” Dr. Avitabile says.

Treatments Dr. Avitabile has explored include not only medicines, but carefully developed exercise programs.

“My personal research program,” Dr. Avitabile says, “focuses on the impact of skeletal muscle defects on exercise performance in children with congenital heart defects and pulmonary hypertension. I am piloting exercise training programs to improve the skeletal muscle, which may in turn improve exercise performance and quality of life in our patients.”

Dr. Avitabile is delighted to be able to translate this award-winning research interest into clinical practice that directly benefits her patients.

“I am most excited by the opportunities to use exercise as an adjunct to pharmacologic therapies,” Dr. Avitabile says. ”I love opportunities to ‘prescribe’ exercise to improve functional status and quality of life in our patients and am excited by the use of wearable activity monitors to track that exercise.”

As an assistant professor of pediatrics at the Perelman School of Medicine at the University of Pennsylvania, Dr. Avitabile has a hand in training the next generation of pediatric cardiologists.

But perhaps the most important teaching she does is focused on her patients and their families: she sees sharing information as a critical part of treatment, and she encourages their curiosity.

“Please be empowered to ask questions,” is Dr. Avitabile’s message to patients’ families. “Please tell me if something does not make sense. Please ask me to explain it again. That is my job!”
