A case of isolated left coronary artery ostial stenosis treated successfully by the saphenous vein patch plasty is reported. A 49-year-old woman was referred for surgery because of unstable angina with subendcardial infarction on ECG. Coronary angiogram showed isolated severe stenosis of left coronary artery ostium without stenotic lesion in the periphery and right coronary artery. At surgery, the aorta was incised obliquely downward to the left coronary ostium and this incision was further extended 8mm distally in the main trunk. Atheromatous left coronary ostium was enlarged with the saphenous vein patch. Postoperatively, angina disappeared and aortic root angioram revealed a well dilated ostium. At 1 year follow-up, the patient remains asymptomatic.
