Complete occlusion of the left main coronary artery: successful surgical management by myocardial revascularization.

Isolated total occlusion of the left main coronary artery was demonstrated on coronary cineangiography in a 50-year-old woman with a progressive anginal syndrome. Aortocoronary saphenous vein graft bypass was performed. Six weeks after operation the patient was free of symptoms and postoperative coronary angiography showed the graft to be patent.
