Anomalous origin of the left coronary artery from the pulmonary artery: late results with special attention to the mitral valve☆

Abstract

(1) Early mortality is related to the severity of preoperative left ventricular dysfunction; it may be reduced by a careful use of postoperative cardiac support techniques. (2) Late results are satisfactory and left ventricular function always recovers. (3) Mitral regurgitation improves along with left ventricular function, but recovery may be incomplete and need reoperation. The data suggest that mitral valve surgery is probably not indicated at initial surgery, except in selected cases with a low potential of recovery (severe regurgitation with relatively well-preserved left ventricular function).
