Comparison of mitral valve geometrical effect of percutaneous edge-to-edge repair between central and eccentric functional mitral regurgitation: clinical implications

摘要

Aims Percutaneous edge-to-edge repair alters mitral valve (MV) geometry in functional mitral regurgitation (FMR). We sought to characterize MV morphology in patients with central and eccentric FMR, compare the geometrical effect of MitraClip therapy, and elucidate different mechanisms of MR improvement according to FMR subtypes.
