Abstract

Mitral valve repair is a complex operation, in which the functionality of incompetent mitral valve is reconstructed by surgical techniques. Simulation-based surgical planning system, allowing surgeons to simulate and compare potential repair strategies, could greatly improve surgical outcomes. This paper presents a practical computational framework, combining the Total Lagrangian Explicit Dynamics Finite Element Method (TLED FEM) and Smoothed Particle Hydrodynamics (SPH), to solve the interaction problem of blood and immersed mitral valves. With this completed pipeline, we can not only predict the mechanical behavior of mitral valve, but also analyze the transvalvular pressures distributed on valve leaflets. The experimental results demonstrate that our method has the potential to be applied in surgical planning simulator of mitral valve repair.
