Abstract:
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.
