The Mitral Valve (MV) is the left atrioventricular valve that controls blood flow between the left atrium and the left ventricle (Fig 1A-B). It has four main components: (i) the mitral annulus — a fibromuscular ring at the base of the left atrium and the ventricle; (ii) two collagenous planar leaflets — anterior and posterior; (iii) web of chordae and (iv) two papillary muscles (PM) that are part of the left ventricle (LV). Normal function of the mitral valve involves a delicate force balance between different components of the valve.
