Mitral Valve Repair

Mitral valve anatomy

The mitral valve consists of an anterior and posterior leaflet. These leaflets are connected to the base of the heart and are anchored by chordae to the inside wall of the left ventricle. The mitral valve leaflets can stiffen or weaken over time and further damage can occur if the chordae stretch, thus preventing proper closure of the two mitral valve leaflets. Severe regurgitation (leakage) or stenosis (narrowing) of the mitral valve can affect the pumping action of the heart by causing excess blood volume and requiring the atrium and ventricle to work harder. Eventually, the atrium and ventricle become enlarged or thickened, which can lead to heart failure and atrial fibrillation if left untreated with mitral valve repair.

Mitral valve repair can avoid the problems associated with mitral valve replacement which include - lifelong blood thinners and reoperations within fifteen years.

Mitral valve repair and treatment options

The mitral valve repair technique requires the clinical expertise of a master cardiac surgeon who has performed a high volume of mitral valve repair procedures. This delicate surgery involves intricate removal of damaged leaflet tissue, detailed reconstruction of overstretched chordae and placement of a stabilizing device around the mitral valve repair, thus allowing restoration of normal heart function.
