Anomalous origin of the right coronary artery (RCA) from the pulmonary artery (PA) is a rare congenital anomaly, and only 28 cases have been reported in the pediatric age group. We describe the case of an infant who had progressive mitral regurgitation and papillary muscle dysfunction in association with anomalous origin of the RCA from the PA. The diagnosis was made by color flow Doppler, confirmed by angiography, and the case was successfully corrected by reimplantation of the anomalous RCA to the aorta. This is only the second case of anomalous origin of the RCA from the PA diagnosed in infancy without an associated congenital anomaly of the heart and great vessels.
右冠状动脉（RCA）起源于肺动脉（PA）是一种罕见的先天性异常，在小儿年龄组中仅报道过28例。我们描述了一名婴儿的病例，该婴儿患有进行性二尖瓣反流和乳头肌功能障碍，同时伴有RCA起源于PA的异常情况。通过彩色多普勒血流显像做出诊断，并经血管造影证实，该病例通过将异常的RCA重新植入主动脉成功得到纠正。这是第二例在婴儿期诊断出的RCA起源于PA且无相关心脏和大血管先天性异常的病例。
