Abstract

We assess the dynamic performance of a novel chorded mitral prosthesis based on the physiology of the human mitral valve using an immersed boundary code. In order to analyse the effect of the ventricle motion on the chorded valve in dynamic opening, in vivo MRI data is used to determine the relative motion of the mitral annulus and the papillary muscles regions of the ventricle. The dynamic fluid-structure interaction model has successfully identified the influences of the ventricle motion on the valve’s mechanical behaviour, and revealed the strengths and weaknesses of the current mitral design. Potential improvements for future designs are also discussed.
