[Surgical pathology analysis of the causes of failure of 48 bioprosthetic heart valves in 40 Chinese cases].
To investigate the pathological changes and related factors leading to failure of bioprosthetic valves. ⋯ Structural valve deterioration is the principle cause of bioprosthetic valve failure while infectious endocarditis mainly involves the valves failure in early and middle terms after surgery. The mode of valve failure in the patients ≤60 years old is different from that in the patients >60 years old at the time of implantation. More calcification would occur in bioprosthetic valve in the younger patients.
