Mitral valve chordae attached to the posterior cusp. Advanced lesions—also commonly involving the posterior leaflet—lead to leaflet folding, inversion, and displacement toward the left atrium. A valve prolapse can result in mitral insufficiency which is a regurgitation or backflow of blood due to the incomplete closure of the valve. Rheumatic heart disease often affects the mitral valve. The valve may also be affected by infective endocarditis Surgery can be performed to replace or repair a damaged valve. A less invasive method is that of mitral valvuloplasty which uses a balloon catheter to open up a stenotic valve. Rarely there can be a
Mitral valve stenosis individuals with a crisp opening snap, score < 8, and no calcium in the commissures. Treatment also focuses on concomitant conditions often seen in mitral stenosis: Mitral valvuloplasty is a minimally invasive therapeutic procedure to correct an uncomplicated mitral stenosis by dilating the valve using a balloon. Under local anaesthetic, a catheter with a special balloon is passed from the right femoral vein, up the inferior vena cava and into the right atrium. The interatrial septum is punctured and the catheter passed into the left atrium using a "trans-septal technique." The balloon is sub-divided into 3 segments and is dilated
