Anomalous origin of the left coronary artery from the pulmonary artery in a premature infant with preserved left ventricular function.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare condition. The majority of cases present with impaired left ventricular function. We report on a premature infant who was diagnosed at a gestational age near term with ALCAPA during routine cardiac examination. The patient showed no signs of myocardial ischemia and is doing well after corrective surgery. This is the youngest patient reported with ALCAPA and preserved myocardial function.
