A 1-year-old boy was referred to our hospital for further investigation of mitral regurgitation. Color-Doppler echocardiography revealed the site of the anomalous origin of the left coronary artery which was confirmed by a cineangiographic study. This case is interesting for several reasons: the first is that the anomalous left coronary artery originated from the right pulmonary artery; the second is that two-dimensional echocardiographic findings can be misleading, i.e., a vessel-like structure which seemed to be the left coronary artery arising normally from the aorta was visualized; and the last is that a two-dimensional color-Doppler echocardiogram was useful in the diagnosis of the anomalous origin of the left coronary artery. The patient underwent implantation of the anomalous left coronary artery as well as Kay's plasty of the mitral valve, and has been doing well since then.
一名1岁男孩因二尖瓣反流进一步检查被转诊至我院。彩色多普勒超声心动图显示左冠状动脉异常起源部位，该部位经电影血管造影研究得以证实。该病例之所以有趣有几个原因：一是异常左冠状动脉起源于右肺动脉；二是二维超声心动图检查结果可能产生误导，即可见一个看似正常发自主动脉的类似血管结构；最后一点是二维彩色多普勒超声心动图对诊断左冠状动脉异常起源很有用。该患者接受了异常左冠状动脉植入术及二尖瓣凯氏成形术，此后情况良好。
