Abstract

Congenital atresia of the left main coronary ostium is a rare coronary anomaly presenting in adulthood. A 48-year-old man presented with unstable angina. Coronary angiography showed an absent left coronary ostium with a super-dominant right coronary artery retrogradely filling the left system. Computed tomography-angiography with 3-dimensional reconstruction confirmed the absence of the left main coronary artery. In view of ongoing chest pain, the patient was offered coronary artery bypass surgery. Total arterial revascularization was performed with a left internal mammary artery-left radial artery Y-graft.

摘要

先天性左冠状动脉开口处闭锁是一种罕见的成年期出现的冠状动脉异常。一名48岁男性因不稳定型心绞痛就诊。冠状动脉造影显示左冠状动脉开口缺如，右冠状动脉优势明显，逆行充盈左心系统。计算机断层扫描血管造影三维重建证实左冠状动脉主干缺如。鉴于持续胸痛，为该患者实施了冠状动脉搭桥手术。采用左乳内动脉-左桡动脉Y型移植进行了全动脉血运重建。
