Double right coronary artery (RCA) arising from two separated ostia in the right sinus of Valsalva is an extremely rare coronary artery variation. We report a case of double RCA detected by multidetector-row computed tomography (MDCT). MDCT allows three-dimensional comprehension of the coronary artery anatomy and it is extremely useful to identify coronary artery anomalies.
双右冠状动脉(RCA)起源于右房室窦的两个分开的开口,是一种极其罕见的冠状动脉变异。我们报告了一例通过多排螺旋 CT(MDCT)检测到的双 RCA 病例。MDCT 允许对冠状动脉解剖结构进行三维理解,对于识别冠状动脉异常非常有用。
