Abstract
As an approach to coronary artery (CA) ostial injury in type A aortic
dissection (TAAD) 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 favorable preliminary results imply
that this technique is a simple, safe, and effective approach to
coronary ostial repair in patients with TAAD or infective endocarditis.
