Anomalous origin of the right coronary artery (RCA) is a rare congenital anomaly, which may cause myocardial ischemia and sudden death. However, the causes of myocardial ischemia remain uncertain. Multidetector row computed tomography (MDCT) was performed in a 22-year-old woman who had exercise-induced myocardial ischemia. MDCT revealed a small orifice of the RCA in the left sinus of Valsalva, separate from the left main coronary artery, an acute-angled takeoff from the aorta, an intramural course of the proximal portion within the aortic wall, and a course between the great vessels. Three-dimensional virtual angioscopy also depicted a small orifice.
右冠状动脉（RCA）异常起源是一种罕见的先天性异常，可能导致心肌缺血和猝死。然而，心肌缺血的原因仍不确定。对一名有运动诱发心肌缺血的22岁女性进行了多排螺旋计算机断层扫描（MDCT）。MDCT显示RCA在主动脉左窦的开口较小，与左冠状动脉主干分离，从主动脉呈锐角发出，近端部分在主动脉壁内走行于壁内，且走行于大血管之间。三维虚拟血管镜检查也显示了一个小开口。
