Abstract :
In this study, an ideal elliptical left ventricle was simulated with a prosthetic heart valve placed at the mitral orifice. The deformation of the left ventricle was predefined, and fluid-structure interaction (FSI) approach was applied to the prosthetic mitral heart valve. The simulation results have shown that the anterior and posterior leaflets behaved differently due to the non-uniform ventricular flow at downstream.
