Double right coronary artery (RCA) is an extremely rare coronary artery anomaly. We here report an atherosclerotic double RCA which appeared after primary percutaneous intervention performed to treat a 34-year-old male presenting with acute inferior myocardial infarction, cardiogenic shock and complete heart block. This is an unusual case as double RCA had been hidden by total atherosclerotic occlusion of the proximal part of the RCA and complete restoration of patency led complete heart block back to normal sinus rhythm.

双支右冠状动脉（RCA）是一种极其罕见的冠状动脉异常。我们在此报告一例动脉粥样硬化性双支右冠状动脉病例，该病例出现在对一名34岁患有急性下壁心肌梗死、心源性休克和完全性心脏传导阻滞的男性进行的初次经皮介入治疗后。这是一个不寻常的病例，因为双支RCA被RCA近端的完全动脉粥样硬化闭塞所掩盖，而通畅的完全恢复使完全性心脏传导阻滞恢复为正常窦性心律。
