Transaortic patch angioplasty for left main coronary artery occlusion

Isolated total occlusion of the left main coronary artery is rare, and may be conventionally treated by standard bypass surgery. We describe a 54- year-old woman with isolated left main coronary artery disease presenting as unstable angina of 1 week's duration. She was treated with transaortic autologous pericardial patch angioplasty. Postoperative coronary angiography showed a widely patent left main coronary artery. She was angina-free 5 months postoperatively. In selected patients, this technique offers a valuable alternative to coronary artery bypass with the advantage of restoring more physiologic perfusion to the coronary tree.
