摘　　要：We presented a case of anomalous single-coronary artery detected incidentally during routine coronary angiography. A 32-year-old male Chinese patient presented with recurrent pre-syncope and six episodes of syncope. Coronary angiography and coronary-computed tomography (CT)-angiography performed by a dual-source computed tomography (DSCT) revealed that the patient had a single large right coronary artery. A moderately large branch originated from the proximal part of the single right coronary artery and extended to the left,passing the anterior to the pulmonary artery,and divided into the anterior descending artery branch and circumflex branch at the base of the left auricular appendage. The episodes of the syncope were suspected to be caused by coronary arterial spasm,so this patient was on a regimen of 30 mg of diltiazem every 6 h and had no recurrence of syncope during follow-up.We presented a case of anomalous single-coronary artery detected incidentally during routine coronary angiography.
