Abstract:
Reconstructive surgery of the left coronary artery system was performed in two adult patients with anomalous origin of the left coronary artery from the pulmonary artery. Postoperative studies were carried out at 2 months and at 49 months. Left ventricular volume, left ventricular myocardial mass, and ejection fraction were normal postoperatively in one patient. In the second patient, the left ventricular volume was markedly reduced, but the decrease in left ventricular mass was less pronounced. Dilatation and tortuosity of the right coronary artery disappeared postoperatively in both patients. However, the dilatation and tortuosity of the left coronary artery persisted on coronary arteriogram.
