Normal mitral valve function depends on perfect function of the complex interaction between the mitral leaflets, the subvalvular apparatus (chordae tendineae and papillary muscles), the mitral annulus, and the left ventricle (LV). An imperfection in any one of these components can cause the valve to leak.3 *Corresponding author. Tel: +32 4 366 ...
