Mitral valve that aims at restoring proper leaflet adjustment. There are some valvular heart diseases that affect the mitral valve. Mitral stenosis is a narrowing of the valve. This can be heard as an opening snap in a heart sound which is not normally present. Classic mitral valve prolapse is caused by an excess of connective tissue that thickens the spongiosa layer of the cusp and separates collagen bundles in the fibrosa. This weakens the cusps and adjacent tissue, resulting in an increased cuspal area and lengthening of the chordae tendineae. Elongation of the chordae tendineae often causes rupture, commonly to the
Mitral insufficiency systolic regurgitant murmur may still be associated with significant hemodynamic consequences. The mitral valve apparatus comprises two valve leaflets, the mitral valve annulus, which forms a ring around the valve leaflets, and the papillary muscles, which tether the valve leaflets to the left ventricle and prevent them from prolapsing into the left atrium. The "chordae tendineae" are also present and connect the valve leaflets to the papillary muscles. Dysfunction of any of these portions of the mitral valve apparatus can cause regurgitation. The most common cause of MR in developing countries is mitral valve prolapse (MVP). and is the most
