Repeated valve replacement: approaches and devices (literature review)

Bioprosthetic valve dysfunction represent a serious drawback that limits the wider clinical use of these medical devices for valvular heart disease surgery. Modern studies describe view pathophysiologists on this problem as multifactorial multi-stage process causes irreversible changes in bioprosthesis components, ultimately leading to its dysfunction. However, addition under- standing and manifestations prosthetic dys- function, an applied question arises about treatment strategies — determining most attenuated accessible low-risk method/ device. The aim review was analyze systematize current literature data methods designs used repeated surgical transcatheter interventions valves.
