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 stenosis left atrium correlates with the severity of the mitral stenosis. As the severity of the mitral stenosis increases, the pressure in the left atrium increases, and the mitral valve opens earlier in ventricular diastole. A mid-diastolic rumbling murmur with presystolic accentuation will be heard after the opening snap. The murmur is best heard at the apical region and is not radiated. Since it is a low-pitch sound, it is heard best with the bell of the stethoscope. Its duration increases with worsening disease. Rolling the patient toward left as well as isometric exercise will accentuate the murmur. A thrill might
