Abstract
The paper presents a multi-physics and multi-scale modeling approach on the closure dynamics of a bileaflet prosthetic heart valve. The modeling methodology consists of coupling a multi-scale model of the left ventricle contraction to a 3D CFD-FSI model, in order to investigate the closure of a cavity pivot bileaflet valve. The rebound motion of the valve is also modeled. The potential of the valve to generate thrombogenic and cavitation effects are assessed on the basis of the duration for which the blood flow is exposed to elevated wall shear stress, large negative pressure transients and increased flow vorticity. A special attention is given to the flow field in the hinge region of the valve.
