Abstract:
Two patients with isolated coronary ostial stenosis were successfully treated by patch angioplasty. These two cases were compared angiographically with 49 conventional CABGs for distal coronary stenosis. The patch angioplasty of the ostium can create an large internal diameter, prevent competitive flows, and can be made under limited dissection at reoperation. For isolated coronary ostial stenosis this method is superior to the CABG to the left anterior descending and/or circumflex coronary arteries in which retrograde flow or stasis may occurred.
