Fully Coupled Fluid Structure Interaction Simulation of Bioprosthetic Heart Valves: A Numerical and Experimental Analysis
… to consider accurate properties of bioprosthetic heart valves (BHVs), such as density and mechanical properties. Previous computational studies assumed (bovine pericardium) BP used in BHVs density was comparable to water or blood. Yet, BP is subjected to multiple treatments like fixation and …

Bioprosthetic heart valves : ultrastructure and calcification
… to 72 hours. In order to assess the pre-fixation tissue damage arising from the hypoxic period and the resulting calcific degeneration after implantation, we used an ultrastructural damage score and transmission electron microscopy. Materials and Methods: In a step by step manner, three major …
