Isolated single coronary artery is a rare congenital anomaly occuring in approximately 0.024% of the population. This entity can be diagnosed during life only by coronary angiography. Ten patients with isolated single coronary artery are reported. Based on angiographic analysis, a new classification is proposed, according to the site of origin and anatomical distribution of the branches. Typical angina did not occur with single coronary artery in the absence of coexisting coronary artery disease or aortic stenosis. No correlation was apparent between the type of anomalous patterns and the symptoms of angina.
孤立性单冠状动脉是一种罕见的先天性异常，在大约0.024%的人群中出现。这种情况只能在生前通过冠状动脉造影来诊断。本文报告了10例孤立性单冠状动脉患者。基于血管造影分析，根据分支的起源部位和解剖分布提出了一种新的分类方法。在没有并存冠状动脉疾病或主动脉狭窄的情况下，单冠状动脉不会出现典型心绞痛。异常模式的类型与心绞痛症状之间没有明显的相关性。
