Key result
Coronary ostial repair using a ring-shaped bovine pericardial patch successfully managed 4 patients with type A aortic dissection or infective endocarditis, showing patent coronary ostia at follow-up.
Why the study?
To describe a technique using a ring-shaped bovine pericardial patch for repairing coronary artery ostial injury in type A aortic dissection and infective endocarditis.
Does coronary ostial repair using a ring-shaped bovine pericardial patch result in patent coronary ostia in patients with type A aortic dissection or infective endocarditis?

Does coronary ostial repair using a ring-shaped bovine pericardial patch result in patent coronary ostia in patients with type A aortic dissection or infective endocarditis?
A ring-shaped bovine pericardial patch provides a simple, safe, and effective technique for coronary ostial repair in patients with type A aortic dissection or infective endocarditis.
May support patch use in select complex cases; leaves open durability and generalizability in larger studies.
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.
