We report an exceptional case of ischemic heart disease due to the origin of the left coronary circumflex artery from the pulmonary artery in a 50-year-old woman. She had undergone surgery for aortic coarctation when she was 16 years old. This abnormality was associated with other congenital defects such as tunnel subaortic stenosis, small aortic valve annulus, numerous left ventricular false tendons, and aortic bicuspid valve. Cardiac surgery verified the origin of the left circumflex from the pulmonary artery. The left internal mammary artery was positioned on the obtuse marginal coronary branch. Her clinical state was moderately improved 3 months after surgery.
我们报告了一例罕见的缺血性心脏病病例，病因是一名50岁女性的左旋支冠状动脉起源于肺动脉。她16岁时接受了主动脉缩窄手术。这种异常与其他先天性缺陷相关，如主动脉下隧道狭窄、主动脉瓣环小、大量左心室假腱索和主动脉二叶瓣。心脏手术证实了左旋支起源于肺动脉。左乳内动脉位于钝缘冠状动脉分支上。术后3个月，她的临床状况有中度改善。
