Mobile abnormal structures in the aortic valve are difficult to diagnose in some cases. We describe a rare clinical case of fibrous strand rupture in a dialysis patient, which was surgically treated. Preoperative echocardiography showed a mobile structure attached to the noncoronary cusp, and intraoperative findings revealed rupture of the fibrous strand in this cusp. If aortic regurgitation without obvious cause is noted in cases of abnormal mobile structures, fibrous strand rupture could be a differential diagnosis.
在某些情况下，主动脉瓣内的移动性异常结构很难诊断。我们描述了一例透析患者纤维束破裂的罕见临床病例，并对其进行了手术治疗。术前超声心动图显示一个附着于无冠瓣的移动结构，术中发现该瓣叶的纤维束破裂。如果在存在异常移动结构的病例中发现无明显原因的主动脉瓣反流，纤维束破裂可能是一种鉴别诊断。
