Computational fluid-structure interaction modeling suggests that a 12 mm leaflet height optimizes hemodynamics and stress distribution in a 19 mm bioprosthetic aortic valve.
Firoozan et al. (2016) studied Valvular damages. Bioprosthetic heart valve simulation (19 mm diameter) vs. Various leaflet geometries was evaluated on Hemodynamic parameters and Von Mises stress. Simulation of a 19 mm bioprosthetic heart valve indicated that a leaflet with 12 mm height is the optimal geometry for hemodynamic parameters and Von Mises stress.
