Tetralogy of Fallot | American Heart Association

Tetralogy of Fallot is treated with two kinds of surgery. One provides temporary improvement by a shunt to give more blood flow to the lungs. The other is a complete repair of the two most important abnormalities that make up tetralogy of Fallot. Patients might have one or both surgeries in their lifetime.
