A 35-year-old woman with angina of five years duration underwent elective cardiac catheterization and coronary angiography which revealed left main stenosis. Immediately afterwards, the patient became distressed, hypotensive and bradycardic. She died despite emergency percutaneous transluminal coronary angioplasty and resuscitative efforts. Autopsy confirmed isolated left coronary ostial stenosis due to the combination of a congenital abnormality of the ostium and initial segment of left main coronary artery, together with a superimposed myointimal flap bridging the ostium. A unique association was an abnormal configuration of the ostia of the branches of the aortic arch.
一名患有五年心绞痛病史的35岁女性接受了选择性心导管插入术和冠状动脉造影，结果显示左主干狭窄。此后不久，患者出现呼吸困难、低血压和心动过缓。尽管进行了紧急经皮冠状动脉腔内血管成形术并努力进行复苏，但她还是去世了。尸检证实，孤立的左冠状动脉口狭窄是由于左主冠状动脉口和起始段的先天性异常，以及覆盖在口上的肌内膜瓣共同作用所致。一个独特的关联是主动脉弓分支口的异常形态。
