Anomalous coronary artery originating from the aorta without complicated congenital cardiac anomaly is rare. We describe a case with the left coronary artery originating from the right sinus of Valsalva. Cardiac catheterization revealed a left coronary artery transverse between the aorta and the pulmonary artery. Severe atherosclerotic stenosis was present at segment 3 of the right coronary artery. Electrocardiogram and myocardial scintigraphy revealed that the angina occurred due to stenosis of the right coronary artery. We tried PTCA, but could not pass the catheter through the stenosis. After PTCA, he complained of anterior chest pain frequently, so we performed an aortocoronary bypass operation to the right coronary artery with saphenous vein graft. Postoperative course was not eventful and angina disappeared.
起源于主动脉且无复杂先天性心脏异常的异常冠状动脉很少见。我们描述了一例左冠状动脉起源于瓦尔萨尔瓦右窦的病例。心脏导管检查显示左冠状动脉在主动脉和肺动脉之间横行。右冠状动脉第3段存在严重的动脉粥样硬化狭窄。心电图和心肌闪烁显像显示心绞痛是由右冠状动脉狭窄引起的。我们尝试了经皮冠状动脉腔内血管成形术（PTCA），但无法将导管通过狭窄部位。PTCA术后，他频繁抱怨前胸疼痛，因此我们用大隐静脉移植对右冠状动脉进行了主动脉冠状动脉搭桥手术。术后过程平稳，心绞痛消失。
