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 valve annuloplasty the native annulus and some of its natural dynamics. The goal of semi-rigid rings is to maintain coaptation and valve integrity during systole, while allowing for good hemodynamics during diastole. Rigid rings are designed to provide rigid support in large dilation and under high-pressure. Annuloplasty devices usually come in different sizes. The surgeon can estimate the dimensions of the patient’s mitral valve and decide on an appropriate ring size. Depending on the disease etiology, different approaches are taken. Surgeons can decide to "undersize" the device, "truesize" the device, or "oversize" it. Annuloplasty devices are classified by the U.S. Food and
