A patient with the left coronary artery isolated from the ascending aorta is discussed. This is the seventh case described and the third diagnosed preoperatively. In contrast to other patients she had predominant aortic incompetence and was much older (52 years compared with the other patients, all younger than 25 years). She also had two angiograms demonstrating progressive isolation of the coronary artery with time. The patient was managed by aortic valve replacement. It is our belief that the condition is acquired and resulted from fusion of the free edge of the aortic valve leaflet to the supravalvar ridge secondary to an inflammatory process.
本文讨论了一例左冠状动脉与升主动脉分离的患者。这是所描述的第七例病例，也是第三例术前确诊的病例。与其他患者不同的是，她主要表现为主动脉瓣关闭不全，且年龄更大（52岁，而其他患者均小于25岁）。她还进行了两次血管造影，显示冠状动脉随时间逐渐分离。该患者接受了主动脉瓣置换术。我们认为这种情况是后天获得性的，是由于炎症过程导致主动脉瓣叶游离缘与瓣上嵴融合所致。
