Prediction of Blood Flow Velocity and Leaflet Deformation Via 2D Mitral Valve Model

In the mitral valve, regional variations in structure and material properties combine to affect the biomechanics of the entire valve. Previous study, we know that mitral valve leaflet tissue is highly extensible. A two-dimensional model of the mitral valve was generated using an Arbitrary Lagrangian...
