[Angioplasty of the left main coronary artery--report of a case with left main coronary stenosis and aortic valve stenosis].

A 58-year-old woman was admitted to our hospital suffering from repeated chest pain. Selective coronary angiography (CAG) showed severely stenotic lesion in the left main coronary artery. There was no additional lesion in the left anterior descending and circumflex arteries. Aortography showed severe calcification in the aortic valve. The aortic was incised and divided completely at the aortic root 1 cm distal to the aortic valve. The incision was then extended toward the opening of the left coronary artery. An atheromatous plague was found and resected at the ostium. A saphenous vein patch was used to enlarge the internal diameter of the artery. The aortic valve was replaced using #21 SJM prosthetic valve. The patient recovered the surgery well, and anginal attacks have disappeared. Postoperative coronary angiograms revealed no stenotic lesion in the left main coronary artery.
