Abstract
The case of a patient with the new type Bjørk-Shiley aortic and mitral valve prosthesis is described. Three months after implant she suffered acute heart failure and died. Post-mortem examination revealed a fractured outlet strut in the mitral valve prosthesis with dislocation of the disc. The fracture was regarded as due to excessive brittleness caused by demonstrated deposition of chromium-tungsten-carbide.
摘要
描述了一例使用新型比约克-希利主动脉和二尖瓣假体的患者病例。植入后三个月，她出现急性心力衰竭并死亡。尸检发现二尖瓣假体的出口支柱断裂，瓣盘移位。骨折被认为是由于已证实的碳化铬-碳化钨沉积导致的过度脆性所致。
