A 13-year-old girl had recurrent syncope episodes and chest oppression during exercise caused by myocardial ischemia that was confirmed by stress myocardial scintigraphy. Echocardiography revealed mild aortic regurgitation (AR). Cineangiography revealed persistent opacification of the left coronary sinus. Freeing of the adherent left coronary cusp from the aortic wall increased antegrade left coronary flow and commissural resuspension restored AR. Postoperative recovery was uneventful and myocardial ischemia did not develop after surgery. Hence, although left coronary artery ostial isolation by aortic valve leaflet is rare, it can be successfully treated by aortic valve repair.
一名13岁女孩在运动期间反复出现晕厥发作和胸部压迫感，经负荷心肌闪烁扫描证实为心肌缺血所致。超声心动图显示轻度主动脉瓣反流（AR）。心血管造影显示左冠状动脉窦持续显影。将粘连的左冠状动脉瓣叶从主动脉壁上松解，增加了左冠状动脉的顺行血流，瓣叶重新悬吊恢复了主动脉瓣反流。术后恢复顺利，术后未再发生心肌缺血。因此，虽然主动脉瓣叶导致的左冠状动脉开口隔离很少见，但通过主动脉瓣修复可成功治疗。
