Anomalous origin of the left anterior descending coronary artery from the pulmonary artery: surgical correction in an adult.

A 45-year-old female with severe anginal symptoms was found to have anomalous origin of the anterior descending branch of the left coronary artery (LCA) from the pulmonary artery. Proximal ligation and anastomosis with aortocoronary saphenous vein graft (SVG) were performed. There was complete relief of symptoms. Two-year postoperative angiography revealed a patent SVG with excellent flow, normalization of the caliber of the right and left circumflex coronary arteries with complete regression of collaterals, and improved left ventricular function.
