John Thomas Fahey MD

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

Research Interests

Interventional cardiac catheterizations for pediatric and adult patients with congenital heart defects; Exercise physiology in children with congenital heart defects

Research Summary

Dr. Fahey’s research interests include exercise stress testing, interventional cardiac catheterization for congenital heart disease, 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 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.

Dr. Fahey works with Dr. Michael Cleman (the head of the adult interventional catheterization laboratory). They have developed a collaborative approach to the adult patients with congenital heart defects. This includes closure of patent foramen ovale (PFO) in young adults who have had a stroke due to a paradoxical embolis, older adults with atrial septal defects, patent ductus arteriosis, pulmonary valve stenosis, coronary artery fistula and other coronary artery anomalies, coarctation of the aorta, and other more complex forms of congenital heart defects. The team has participate in trials of intervetional catheter delivered devices to treat mitral insufficiency and mitral stenosis. There protocols serve as an excellent complementary service for the Yale-New Haven Adult Congenital Heart Program.
