title: Individual anatomy demands various techniques in correction of an anomalous origin of the left coronary artery in the pulmonary artery.
abstract: Anomalous origin of the left coronary artery (ALCA) from the pulmonary artery is a rare cardiac anomaly. It can result in decreased myocardial perfusion and impaired left-ventricular function, which can lead to congestive heart failure or even myocardial infarction. Reconstructive surgery of the left coronary artery is the desirable measure in the management of this anomaly. Since July 1992, five patients with ALCA from the pulmonary artery were treated surgically. Age at operation ranged from 3 months to 11 years. Three patients had congestive heart failure and one was in cardiogenic shock. Operative techniques included "tunnel type" surgery in three cases and aortic reimplantation in two. Two operative variations performed successfully in this series are described. There were no postoperative deaths. At the latest follow-up (mean 14 months), all anastomoses were patent and showed antegrade flow. For those patients with ALCA from the pulmonary artery, direct reimplantation of the ALCA to the aorta is the most physiologically appropriate reconstructive solution, and offers good early and late results. Intrapulmonary tunnel from aortopulmonary window to coronary artery is recommended for children in whom aortic reimplantation is not anatomically feasible.
