ABSTRACT: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) with preserved ventricular function is a rare congenital coronary artery anomaly when diagnosed in an adult patient and remains an important cause of sudden cardiac death. We report a 42-year-old patient with ALCAPA managed with intrapulmonary interruption of the left main coronary artery (LMCA) ostea and grafting of the LMCA with left internal mammary artery so as to restore antegrade coronary flow. This restores a dual-coronary-artery system and also allows antegrade blood flow as in a normal coronary artery to a large area of viable myocardium. This strategy is simple to accomplish and is more physiological in an anteriorly placed and dilated LMCA as seen in our case.
