A 67-year-old man, who had complete occlusion both of left main coronary artery (LMCA) and right coronary artery (RCA), underwent coronary revascularization. He had been suffering from severe angina pectoris preoperatively. Exercise electrocardiogram (single Master) showed myocardial ischemia. On cardiac catheterization, he showed extensive collaterals from right main coronary artery, and well-preserved left ventricular function. At operation, coronary arteries revealed severe sclerosis, especially in RCA, but there was no evidence of old myocardial infarction. Three saphenous vein grafts were bypassed to LAD, LCX, and RCA. Postoperatively, he remained free of angina pectoris at 6 months after uneventful surgery.
一名67岁男性，左冠状动脉主干（LMCA）和右冠状动脉（RCA）均完全闭塞，接受了冠状动脉血运重建术。他术前一直患有严重心绞痛。运动心电图（单导联Master）显示心肌缺血。心脏导管检查显示，右冠状动脉主干有广泛的侧支循环，左心室功能保存良好。手术中，冠状动脉显示严重硬化，尤其是在右冠状动脉，但没有陈旧性心肌梗死的迹象。三条大隐静脉移植血管分别绕过左前降支、左旋支和右冠状动脉进行搭桥。术后，在手术顺利完成6个月后，他未再出现心绞痛。
