摘要：
An 89-year-old woman with severe aortic stenosis underwent transfemoral aortic valve replacement. The postoperative course was uneventful except transient bradycardia immediately after the procedure. Echocardiographic finding showed excellent valvular function. After discharge, the patient died suddenly. Autopsy findings showed compression of the atrioventricular conduction system region at the septum by the stent strut. Microscopic examination showed atrophy of the conduction fibers with eosinophilic degeneration of the cytoplasm or coagulation necrosis with pyknosis in the bundle of His and the left bundle branch. Compression by the stent strut triggering dysfunction of the conduction system could have caused fatal arrhythmic event. © 2012 Japanese Association of Cardiovascular Intervention and Therapeutics.
