This application note will detail how the SPH technique was used to determine the FSI response of a generic prosthetic heart valve. The smoothed particle hydrodynamic (SPH) analysis method overcomes this difficulty. 1 – Leaflet material test data and Marlow model representation. 2 Fluidstructure interaction (FSI) studies are less common, in part because the closure of the valve creates CFD domain pinching. Finite element (FE) studies have been used to estimate peak stresses in valves, 1 and computational fluid dynamics (CFD) studies have been used to model blood flow around valves. Assessment of fatigue life requires accurate estimates of the stresses induced during the cardiac cycle.

Durability is a key measurement of prosthetic heart valve function.
