Dynamic analysis of the aortic valve functioning

Patralski Krzysztof

Journal of Theoretical and Applied Mechanics

2020

Vol. 58 nr 4

853--869

The aim of the paper was to recognize the influence of mechanical factors on the movement of the leaflets. Mechanical stimuli may have a positive effect on remodeling the leaflet material to adapt its structure to a changing load. A model of the valve functioning process was developed. A geometric model similar to the construction of a natural valve was adopted. The hybrid process of the liquid-solid interaction problem was described. The interaction process was modeled. The problem was formulated with the Galerkin FEM method. Numerical analyses of a single valve work cycle and the calcification process of aortic valve bioprostheses were performed.
