Five cases of anomalous origin of the left main (LM) coronary artery from the right anterior aortic sinus are presented. In 4 patients the anomalous artery ran a septal course through the floor of the right ventricular infundibulum and in 1 an interarterial course between the aorta and pulmonary trunk. The cineangiographic features of these courses are contrasted with arteries running anterior free wall and retro-aortic courses. A caudal anterior loop of the anomalous LM coronary artery indicates a septal course, a cranial posterior loop an interarterial course, a cranial anterior loop an anterior free wall course and a caudal posterior loop a retro-aortic course. Review of previously documented cases shows that the septal course is relatively common, although previously not recognized.
本文报告了5例左冠状动脉主干（LM）起源于右前主动脉窦的病例。4例患者的异常动脉走行于右心室漏斗部底部的间隔路径，1例走行于主动脉与肺动脉干之间的动脉间路径。这些走行的心血管造影特征与走行于前游离壁和主动脉后路径的动脉形成对比。异常左冠状动脉主干的尾侧前环提示间隔路径，头侧后环提示动脉间路径，头侧前环提示前游离壁路径，尾侧后环提示主动脉后路径。对既往文献记载病例的回顾显示，间隔路径相对常见，尽管此前未被认识到。
