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

One cardiac surgery professor said, "I think the only benefit is for cosmesis for the patient and the benefit is for marketing and growing our practices for ourselves because it’s a good way to grow one's practice." Robotic mitral valve repair operations are also being utilized throughout the United States. In the 2000s there have been several trials of a newer strategy of mitral valve repair that does not require major cardiac surgery. Through a catheter inserted in the groin, the valve leaflets are clipped together. This technique – percutaneous mitral valve repair – is
