A variety of complications involving heart valve implants have been documented. Embolism originating from thrombosis of the valve has been a recurrent problem in mechanical and to a lesser extent porcine implants. We report two accidental deaths as a result of embolization of cotton pledgets from porcine valves. Hospital personnel failed to remove this cotton material from the valves before surgical placement. In the first case, when portions of the pledgets embolized to both carotid arteries, fatal cerebral infarction occurred. In the second case, portions of the pledgets embolized to a coronary artery producing severe left ventricular failure.
已记录了多种涉及心脏瓣膜植入物的并发症。源于瓣膜血栓形成的栓塞在机械瓣膜植入物中一直是个反复出现的问题，在猪瓣膜植入物中程度稍轻。我们报告了两起因猪瓣膜棉塞子栓塞导致的意外死亡。医院工作人员在手术植入前未从瓣膜上移除这种棉质材料。在第一例中，当部分棉塞子栓塞到双侧颈动脉时，发生了致命的脑梗死。在第二例中，部分棉塞子栓塞到一条冠状动脉，导致严重的左心室衰竭。
