Abstract

We encountered a 67-year-old woman with a left atrial myxoma which was discovered during echocardiographic examination and emergency coronary arteriography just after an onset of acute inferior myocardial infarction. Coronary arteriography disclosed an abrupt and total occlusion of the right coronary artery and an abnormally large and tortuous atrial circumflex branch feeding a left atrial mass. These findings were the most useful for diagnosis. Aorto-coronary bypass surgery and excision of the myxoma were performed simultaneously by emergency operation. The postoperative course was uneventful. Myocardial infarction in this patient is believed to have been caused by coronary embolization from the left atrial myxoma.

摘要

我们遇到一位67岁女性，她在急性下壁心肌梗死发作后进行超声心动图检查和急诊冠状动脉造影时发现患有左心房黏液瘤。冠状动脉造影显示右冠状动脉突然完全闭塞，以及一条异常粗大且迂曲的心房回旋支为左心房肿物供血。这些发现对诊断最为有用。通过急诊手术同时进行了主动脉-冠状动脉搭桥手术和黏液瘤切除术。术后病程顺利。该患者的心肌梗死据信是由左心房黏液瘤的冠状动脉栓塞所致。
