... valves. A motionless diode, a nozzle, a mechanical bileaflet valve, and a tilting disk valve were tested in a pulmonary mock circulatory system over the normal human range of pulmonary vascular resistance (PVR). For the mechanical valves, regurgitant fractions (RFs) and transvalvular pressure gradients...

...Liang Ge; Hwa-Liang Leo; Fotis Sotiropoulos; Ajit P. Yoganathan Time-accurate, fully 3D numerical simulations and particle image velocity laboratory experiments are carried out for flow through a fully open bileaflet mechanical heart valve under steady (nonpulsatile) inflow conditions. Flows at two...

...K. L. Billiar; M. S. Sacks To date, there are no constitutive models for either the natural or bioprosthetic aortic valve (AV), in part due to experimental complications related to the AV’s small size and heterogeneous fibrous structure. In this study, we developed specialized biaxial testing...
