We present the case of a patient with severe symptomatic aortic valve (AV) stenosis in whom preoperative coronary angiography revealed two separate left circumflex (LCx) arteries, one arising from the left main coronary artery and the other from the right aortic sinus following thereafter a retroaortic course to the left. The pattern of LCx artery anatomy revealed was recognized as one of bilaterally arising twin LCx arteries that is a rare coronary anomaly with only 7 reported cases in the English literature. We discuss the importance of preoperative identification of this anomaly in patients undergoing AV surgery and describe simple clues in order to easily identify it.
我们报告了一例严重症状性主动脉瓣（AV）狭窄患者的病例，其术前冠状动脉造影显示有两条独立的左旋支（LCx）动脉，一条起源于左冠状动脉主干，另一条起源于右主动脉窦，随后向左走行于主动脉后方。所发现的LCx动脉解剖模式被认为是双侧起源的双LCx动脉之一，这是一种罕见的冠状动脉异常，英文文献中仅报道过7例。我们讨论了在接受AV手术的患者中术前识别这种异常的重要性，并描述了一些简单的线索以便于轻松识别它。
