Catherine Avitabile, MD

Core Faculty

Catherine Avitabile, MD is a core faculty member at the Center for Pediatric Clinical Effectiveness (CPCE) at the Children's Hospital of Philadelphia (CHOP), an attending cardiologist in the Division of Cardiology/Section of Pulmonary Hypertension at CHOP, and an assistant professor of pediatrics at the Perelman School of Medicine at the University of Pennsylvania.

Dr. Avitabile’s research program focuses on physical activity, skeletal muscle deficits, and exercise training interventions in children with congenital heart defects and pulmonary hypertension.  Her long-term career goal is to implement interventions to increase physical activity and improve muscle deficits, functional status, and quality of life in children with cardiopulmonary conditions. 

Additionally, Dr. Avitabile collaborates with investigators in the Department of Surgery and Division of Neonatology to advance the care of neonates with developmental lung diseases (congenital diaphragmatic hernia and bronchopulmonary dysplasia) affected by pulmonary hypertension and right ventricular failure.  She studies the association between echocardiographic and laboratory biomarkers of right ventricular function and outcomes in these patient groups in order to develop targeted pulmonary hypertension regimens.

Finally, Dr. Avitabile is an active investigator in the Pediatric Pulmonary Hypertension Network, a multi-center collaboration of pulmonary hypertension experts that aims to advance the care of children with pulmonary hypertension through observational studies and clinical trials.
