A single coronary ostium with no associated congenital cardiac disease is a rare congenital coronary-artery anomaly. However, a single right coronary artery has a much rarer incidence. We report here the antemortem diagnosis of a case with R-I subtype single coronary artery supplying the entire myocardium. A 36-year-old female with chest pain and dyspnea on exertion was admitted to the hospital, whose coronary angiography revealed a single, large coronary artery originating in the right aortic sinus. No observable change was detected in her electrocardiogram and her angiographic examination did not reveal any significant luminal narrowing although she experienced chest pain and dyspnea on exertion. R-I type of single coronary artery is an anomaly with a very rare incidence, which may cause myocardial ischemia and sudden death and whose recognition might be of use to physicians when diagnosing and treating this anomaly.
单一冠状动脉口且无相关先天性心脏病是一种罕见的先天性冠状动脉异常。然而，单一右冠状动脉的发生率要低得多。我们在此报告一例R-I亚型单一冠状动脉供应整个心肌的生前诊断病例。一名36岁女性因胸痛和劳力性呼吸困难入院，其冠状动脉造影显示一条粗大的单一冠状动脉起源于右主动脉窦。尽管她有劳力性胸痛和呼吸困难，但心电图未发现明显变化，血管造影检查也未发现任何明显的管腔狭窄。R-I型单一冠状动脉是一种发病率极低的异常情况，可能导致心肌缺血和猝死，认识这一点可能有助于医生在诊断和治疗这种异常时提供帮助。
