A 73-year-old female began to suffer from effort-induced chest pain and later disabling angina pectoris. Coronary angiographic evaluation disclosed that both the right and left coronary arteries originated from the right sinus of Valsalva. The dominant right coronary artery had a normal course with a 90% narrowing in the first segment. The left main trunk crossed anteriorly the pulmonary artery conus, thereafter dividing into the left anterior descending and circumflex coronary arteries with two 99% narrowings in the seventh and eleventh segment. She underwent bypass of the left anterior descending and right posterior descending coronary arteries with the left interthoracic artery, the right gastroepiploic artery, and saphenous vein graft on cardiopulmonary bypass support. The postoperative course was uncomplicated.
一名73岁女性开始出现劳力性胸痛，后来发展为致残性心绞痛。冠状动脉造影评估显示，右冠状动脉和左冠状动脉均起源于瓦尔萨尔瓦窦右侧。优势右冠状动脉走行正常，第一段有90%的狭窄。左主干向前跨过肺动脉圆锥，随后分为左前降支和左旋支冠状动脉，在第七段和第十一段有两处99%的狭窄。她在体外循环支持下，使用左胸廓内动脉、右胃网膜动脉和大隐静脉移植血管对左前降支和右后降支冠状动脉进行了搭桥手术。术后过程顺利。
