A case of anomalous origin of the left coronary artery from the pulmonary trunk is reported. The patient, a 64-year-old woman, presented with a history of angina and cardiac failure. She was known to have had a mitral systolic murmur since school age. Echocardiography showed clinically significant mitral regurgitation and highly unusual extensive calcification of the mitral valve chordae, papillary muscle, and posterior left ventricular wall--a pattern suggesting the possibility of abnormal coronary circulation. Subsequent cardiac catheterisation confirmed considerable mitral regurgitation with a dilated left ventricle, and arteriography confirmed anomalous origin of the left coronary artery from the main pulmonary trunk. The patient was surgically treated with ligation of the origin of the anomalous left coronary and mitral valve replacement. She was alive and well 2 years after operation.
报道了一例左冠状动脉起源于肺动脉干的病例。患者为一名64岁女性，有心绞痛和心力衰竭病史。自学龄起就已知她有二尖瓣收缩期杂音。超声心动图显示临床上显著的二尖瓣反流以及二尖瓣腱索、乳头肌和左心室后壁高度异常的广泛钙化——这种模式提示冠状动脉循环异常的可能性。随后的心导管检查证实存在大量二尖瓣反流伴左心室扩张，动脉造影证实左冠状动脉起源于主肺动脉干。该患者接受了手术治疗，结扎异常左冠状动脉的起源并进行二尖瓣置换。术后2年她健在且情况良好。
