Right Coronary Artery (RCA) originating from left anterior descending artery is a very rare congenital coronary artery anomaly. A 66-year-old man presented with hypertension and complaints of exertional chest pain. The angiography was performed. Aortic root angiography showed no coronary ostium originating from the right sinus of valsalva. Right coronary artery was visualized as anomalously originating from the midportion of left anterior descending artery. Severe stenosis were seen in ostium of anomalous right coronary artery, in midportion of left anterior descending and in midportion of circumflex artery. The patient was referred for coronary artery bypass grafting. The patient underwent coronary artery bypass surgery for three vessels. He was discharged home on postoperative day 7 without any complication. His echocardiogram on follow-up visit revealed good biventricular function.
起源于左前降支动脉的右冠状动脉是一种非常罕见的先天性冠状动脉异常。一名66岁男性，有高血压病史，主诉劳力性胸痛。进行了血管造影。主动脉根部血管造影显示无冠状动脉开口起源于主动脉瓣窦右窦。右冠状动脉显示异常起源于左前降支动脉中部。异常右冠状动脉开口处、左前降支动脉中部和回旋支动脉中部可见严重狭窄。该患者被转诊进行冠状动脉旁路移植术。患者接受了三支血管的冠状动脉搭桥手术。术后第7天出院，无任何并发症。随访时他的超声心动图显示双心室功能良好。
