John T. Fahey, MD, is director of Yale Medicine’s Adult Congenital Heart Program. A cardiologist, he has more than 30 years of experience treating congenital heart disease in children and adults. He tells new patients, “We can usually make your heart function very close to normal.”

Dr. Fahey researches exercise in patients with congenital heart disease. He also studies the abnormal physiology of congenital heart disease, and when and how to best treat it.”

He derives his greatest satisfaction from caring for young patients over time and watching them grow into adults. He is most excited about new catheterization methods that enable a patient with congenital heart disease to avoid surgery. He is a professor of pediatrics (cardiology) and an associate clinical professor of nursing at Yale School of Medicine.
