[A case of successful surgery for atrial septal defect accompanied with angina pectoris].

A 59-year-old patient with atrial septal defect (ASD) and angina pectoris due to 99% stenosis of the anterior descending coronary artery (LAD) was successfully treated by closure of ASD and coronary artery bypass grafting (CABG) to the LAD #7 with a saphenous vein graft. Preoperatively, the right ventricle was overloaded with high pulmonary arterial pressure (52 mmHg) and anterior segmental wall motion of the left ventricle was reduced probably due to myocardial ischemia. Combined operation, ASD closure and CABG, made these impairments normal and resulted in disappearance of the chest pain and reinstatement to his former job.
