A single coronary artery (SCA) is a rare congenital anomaly of the coronary circulation, which is often associated with myocardial ischemia and other congenital cardiac anomalies. A 77-year-old woman visited our hospital complaining of typical chest pain. Coronary angiography revealed an isolated SCA. The right coronary artery did not originate from the aorta, but instead emerged from the distal left circumflex artery, with significant stenosis at the proximal portion of the left anterior descending artery. A stent was successfully implanted at the culprit lesion. There was no perfusion defect detected by a cardiac SPECT study.
单支冠状动脉（SCA）是一种罕见的冠状动脉循环先天性异常，常伴有心肌缺血和其他先天性心脏异常。一位 77 岁女性因典型胸痛就诊于我院。冠状动脉造影显示孤立性 SCA。右冠状动脉不是起源于主动脉，而是发自左回旋支的远段，左前降支近段有明显狭窄。在罪犯病变部位成功植入支架。心脏 SPECT 检查未发现灌注缺损。
