The prevalence of congenital coronary artery anomalies is approximately 1% in the general population. They are a common cause of sudden death in younger persons. Congenital absence of the left circumflex artery is usually a benign condition but can cause symptoms of exertional angina. We present a case of a 59-year-old female who presented with complaints of chest pain. She was evaluated by the cardiology service. An invasive angiogram identified the absence of the circumflex artery, a large right coronary artery, and large septal and diagonal branches of the left main coronary artery possibly as a compensatory mechanism to supply blood to the LCx territories. It is important to define coronary anatomy as anomalies dictate which cardiac intervention should be attempted in cases of ischemia.
先天性冠状动脉异常在普通人群中的患病率约为1%。它们是年轻人猝死的常见原因。先天性左旋支动脉缺如通常是一种良性情况，但可引起劳力性心绞痛症状。我们报告一例59岁女性，她因胸痛前来就诊。她接受了心脏病科的评估。有创血管造影显示左旋支动脉缺如、右冠状动脉粗大以及左主冠状动脉的粗大间隔支和对角支，这可能是为左旋支动脉供血区域供血的一种代偿机制。明确冠状动脉解剖结构很重要，因为异常情况决定了在缺血病例中应尝试何种心脏干预措施。
