Objective To analyze of the MSCT features of the infants with coronary artery originated from the pul-monary artery, to improve the diagnosis of the disease. Methods The CT data of two cases of ACAPA from September 2014 to June 2015 were retrospectively analyzed. Results The diagnosis of ACAPA was found in 2 cases. MSCT showed that one case of right coronary artery originating from the right sinus of the pulmonary artery, and one case of left coronary artery originating from the posterior sinus of the pulmonary artery. Conclusion Anomalous origin of the coronary artery from the pulmonary artery is a rare congenital heart disease, MSCT can be considered as a non inva-sive and reliable imaging technique for diagnosis of congenital coronary artery anomaly.%目的 分析婴幼儿冠状动脉起源于肺动脉的MSCT表现特点,以提高对该病的诊断. 方法 收集2014年9月~2015年6月2例冠状动脉起源于肺动脉的CT表现, 并作文献复习. 结果 诊断冠状动脉异常起源于肺动脉2例,MSCT显示1例右侧冠状动脉异常起源于肺动脉右窦,1例左侧冠状动脉起源于肺动脉后窦. 结论 冠状动脉异常起源于肺动脉为少见的先天性心脏病,MSCT可作为一种可靠的、有潜力的无创伤性诊断方法应用于其诊断中.
