Abstrakt: In an adult patient, coronary artery fistula involving the circumflex artery (CX) connected to the coronary sinus caused aneurysm of the left main and CX associated with ectasia of the intermediate branch. The patient had posterolateral infarction with severe ischemic mitral regurgitation and moderate tricuspid regurgitation. A rare venous return anomaly was also present. The inferior vena cava, which was interrupted at the level of the liver, continued with the hemiazygos to drain into a persistent left superior vena cava, which in turn drained into the coronary sinus. Surgery included CX closure and mitral and tricuspid repair. The strategy had to be adapted to the anatomy. The fistula was dissected and snared for cardioplegia delivery, and venous return was achieved by cannulation of the superior vena cava and femoral vein. The procedure was uneventful, and 4 years later the patient is asymptomatic.
