Repair of coronary artery ostium with a ring-shaped bovine pericardial patch

Abstract

Abstract As an approach to coronary artery ostial injury in type A aortic dissection and infective endocarditis, we describe a technique of coronary ostial repair using a ring-shaped bovine pericardial patch. The inner and outer rims of the patch were sutured to the involved coronary ostium (to close the ostial tear) and to the aortic wall (to cover the sinus), respectively. Four patients were successfully managed and computed tomographic coronary arteriogram at follow-up showed patent coronary ostia and arteries. The favourable preliminary results imply that this technique is a simple, safe and effective approach to coronary ostial repair in patients with type A aortic dissection or infective endocarditis.
