Patch repair of anomalous origin of the left main coronary artery from the anterior aortic sinus.

Abstract

Anomalous origin of the left main coronary artery from the anterior aortic sinus is a rare but potentially lethal congenital disease. We report two adolescent patients with this anomaly who underwent surgical plasty using a saphenous vein patch, rather than unroofing or fenestration technique, as was typically done. This report suggests that surgical angioplasty can be performed safely and effectively to treat this anomaly.
