Anomalous coronary arteries are a rare condition, but they may cause myocardial ischemia, heart failure, and sudden death. We evaluated the prevalence and multislice computed tomographic (MSCT) findings of anomalous coronary arteries in a large number of patients from the multicenter registry. At four institutes, 29 (0.74%) out of 3910 patients were found to have anomalous coronary arteries by MSCT. They consisted of 15 patients with anomalous origins of the right coronary artery, 1 with right-sided origin of the left circumflex artery, 1 with right-sided origin of the left main coronary artery, 2 with double right coronary arteries, 2 with the absence of the left circumflex artery, 1 with absence of the right coronary artery, 6 with coronary artery fistulas, and 1 with Bland-White-Garland syndrome. Multislice computed tomography findings were consistent with those obtained by conventional coronary angiography in all 14 patients undergoing both diagnostic procedures. Multislice computed tomography permits three-dimensional comprehension of coronary arteries, which is suitable for the diagnosis of anomalous coronary arteries.
冠状动脉异常是一种罕见的病症，但可能导致心肌缺血、心力衰竭和猝死。我们通过多中心登记研究评估了大量患者中冠状动脉异常的患病率及多层螺旋计算机断层扫描（MSCT）表现。在四家机构中，3910例患者中有29例（0.74%）经MSCT检查发现冠状动脉异常。其中包括15例右冠状动脉起源异常、1例左旋支动脉起源于右侧、1例左主冠状动脉起源于右侧、2例双右冠状动脉、2例左旋支动脉缺如、1例右冠状动脉缺如、6例冠状动脉瘘以及1例布兰德-怀特-加兰综合征。在接受两种诊断检查的所有14例患者中，多层螺旋计算机断层扫描结果与传统冠状动脉造影结果一致。多层螺旋计算机断层扫描可对冠状动脉进行三维成像，适用于冠状动脉异常的诊断。
