Choice of design of transcatheter aortic valve prosthesis frame based on finite element analysis

— This article presents an analysis of the impact of the transcatheter prosthesis frame design features on the results of its implantation in the aortic root model. In this paper we analyzed the various approaches to the design of such structures, as well as modifications in order to improve their functional characteristics during the implantation. As a general method for obtaining the results of interaction of the objects was used finite element method with nonlinear materials description and analysis of the main parameters: the stress-strain state, radial and friction forces.
