A 55-year-old man who had been asymptomatic after replacement of his aortic valve with a Bjork-Shiley prosthesis, suddenly developed heart failure. The clinical suspicion of prosthetic malfunction was not only confirmed, but specified as being a stuck disc secondary to a large thrombus. Surgical removal of the clot resulted in restoration of normal function and return to the expected findings on echocardiogram. The value of echocardiography in such instances, as well as in routinely following-up patients with prostheses postoperatively, is emphasized.
一名55岁男性在使用Bjork-Shiley人工心脏瓣膜置换主动脉瓣后一直无症状，却突然出现心力衰竭。临床怀疑人工瓣膜功能障碍不仅得到证实，而且确定为继发于大量血栓的卡瓣。手术清除血栓后功能恢复正常，超声心动图检查结果也恢复到预期状态。强调了超声心动图在这类病例中的价值，以及在人工瓣膜置换术后患者常规随访中的价值。
