Repairing the Heart: Unifocalization

In this interactive 3-D animation, our doctors compare a healthy heart to one with a complex congenital condition called tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries (MAPCAs). They also guide you through the innovative repair technique, called unifocalization, which involves rebuilding the blood vessel connection between the heart and lungs, usually in just one surgery.
