Abstract
The fracture of the outlet strut of a Bjørk-Shiley artificial heart valve implanted in a 21 year old man lead--6 years after the operation--to the valve disc jamming closed with a resulting lethal heart failure and circulation standstill. The probable cause of the valve strut fracture could be determined by metallurgical/metallographical investigation of the material and the production methods.
摘要
一名21岁男性植入的Bjørk-Shiley人工心脏瓣膜出口支柱发生骨折，术后6年导致瓣膜盘卡闭，最终导致致命的心力衰竭和循环停止。通过对材料和生产方法进行金相/金相学调查，可以确定瓣膜支柱骨折的可能原因。
