Professor of Pediatrics (Cardiology) and Associate Clinical Professor of Nursing; Director, Pediatric Exercise Laboratory; Director, Pediatric Cardiology Fellowship Program; Director, Adult Congenital Heart Program

Research Interests

Exercise physiology in children with congenital and acquired heart defects. Adults with congenital heart disease.


Research Summary

Dr. Fahey’s research interests include exercise stress testing, and Adults with Congenital Heart Disease. Research in the exercise laboratory has included patients with congenital heart defects, as well as children with obesity, rickets, pulmonary arteriovenous fistulas, and stridor. He is now the exercise core laboratory for an international study investigating the effects of a transcatheter placed pulmonary valve on exercise performance. In addition, he is now a member of the Pediatric Exercise Network, an international group attempting to standardize pediatric integrative physiology, exercise testing, and body composition measurements throughout the US.

Research in the Adult Congenital Heart Disease clinic includes investigting liver dysfunction in adults with complex congenital heart disease.
