A single coronary artery (SCA) arising from the sinus of Valsalva and supplying the entire heart is a rare congenital anomaly. According to the modified Lipton's classification, R-1 is by far the most rare subtype of SCA, with an incidence of 0.0008% in patients undergoing coronary angiography. We present a case with an unreported anomaly, classified as Lipton R-I subtype, which initially followed the normal course of the right coronary artery. The posterior descending artery then proceeded as the distal and middle sections of the left anterior descending artery, while the posterolateral branch proceeded as the left circumflex artery and finally terminated as the proximal left anterior descending artery. The patient underwent percutaneous intervention in the posterolateral branch for an acute coronary syndrome.
一条源于主动脉窦并供应整个心脏的单一冠状动脉（SCA）是一种罕见的先天性异常。根据改良的利普顿分类法，R-1是SCA迄今为止最罕见的亚型，在接受冠状动脉造影的患者中发病率为0.0008%。我们报告一例具有未报道异常的病例，分类为利普顿R-I亚型，其最初走行于右冠状动脉的正常路径。而后降支动脉接着走行于左前降支动脉的远端和中段，而外侧后支动脉则走行于左旋支动脉，最终终止于左前降支动脉近端。该患者因急性冠状动脉综合征在外侧后支接受了经皮介入治疗。
