Chronic left ventricular failure developed two months after ligation of an apparently uncomplicated large ductus arteriosus in a one year old girl. Two years later deterioration had progressed to a terminal stage. An anomalous left coronary artery arising from the pulmonary artery had not been recognised before duct ligation. This anomaly was diagnosed two years after ligation and was then treated by surgical redirection, but the patient died of severe left ventricular dysfunction.
一名1岁女童在结扎明显无并发症的大型动脉导管两个月后出现慢性左心室衰竭。两年后病情恶化至晚期。在结扎导管之前未识别出起源于肺动脉的异常左冠状动脉。结扎两年后诊断出该异常，随后进行了手术改道治疗，但患者死于严重的左心室功能障碍。
