Anomalous left coronary artery from pulmonary artery. Unusual case complicated by coronary arterial disease and fistula from coronary artery to left ventricle.
A 42-year-old woman with an anomalous left coronary artery originating from the pulmonary artery and a fistula from the left coronary artery to the left ventricle was treated by aortocoronary bypass grafting of an autologous saphenous vein. The presence of an abundant collateral circulation and of fistulous communications between the left coronary artery and the left ventricle, in our opinion, was the reason that this patient remained asymptomatic until the age of 40 years. We believe that this is the first report of the findings in an adult patient who had these two rare congenital anomalies complicated occlusive coronary arterial disease.
