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.
两名孤立性冠状动脉开口狭窄患者通过补片血管成形术成功治愈。将这两例与49例因冠状动脉远端狭窄行传统冠状动脉旁路移植术（CABG）的患者进行血管造影对比。冠状动脉开口补片血管成形术可形成较大内径，防止血流竞争，且可在再次手术时有限的解剖操作下完成。对于孤立性冠状动脉开口狭窄，该方法优于对左前降支和/或左旋支冠状动脉行CABG，后者可能出现逆向血流或血流淤滞。
