Surgical repair of anomalous origin of the left coronary artery arising from the left pulmonary artery.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly. We report an extremely uncommon variety of ALCAPA, in which the left coronary artery arose from the left pulmonary artery in a patient who presented with severe heart failure in early infancy. After direct reimplantation of the left coronary artery into the ascending aorta, the patient's cardiac function recovered successfully.
