The prevalence of coronary artery anomalies is reported to be around 0.3-1 %. An anomalous origin of the right coronary artery (RCA) is a rare condition but may lead to myocardial ischemia and sudden death. Diagnosis is mainly made by conventional coronary arteriography. Nowadays, multislice computed tomography is a new noninvasive imaging technique with excellent spatial resolution which can detect the origin and course of an anomalous coronary vessel. Here we report on a 67-year-old woman with an anomalous origin of the RCA arising from the pulmonary trunk. The anomaly was diagnosed by cardiac catheterization and confirmed by multislice computed tomography.
据报道，冠状动脉异常的发生率约为0.3%-1%。右冠状动脉（RCA）起源异常是一种罕见的情况，但可能导致心肌缺血和猝死。诊断主要依靠传统冠状动脉造影。如今，多层螺旋CT是一种新的无创成像技术，具有出色的空间分辨率，能够检测异常冠状动脉的起源和走行。在此，我们报告一名67岁女性，其右冠状动脉起源于肺动脉干。该异常通过心导管检查诊断，并经多层螺旋CT证实。
