Xenopericardial Graft Selection for Valve Apparatus of Transcatheter Heart Valve Bioprosthesis

Samples of commercial and noncommercial xenopericardial grafts of different origin and processing are analyzed. A full-scale test of uniaxial stretching of the material was used to evaluate the features of physical and mechanical properties of the samples, and a computer finite element method simula...

Description
Summary:Samples of commercial and noncommercial xenopericardial grafts of different origin and processing are analyzed. A full-scale test of uniaxial stretching of the material was used to evaluate the features of physical and mechanical properties of the samples, and a computer finite element method simulation was used to evaluate the degree of the object compression. The results were analyzed in terms of the capacity of selected pericardial grafts to serve as a valve apparatus of a transcatheter heart valve prosthesis.
