Heart valve repair Heart valve repair Heart valve repair is a surgical technique used to fix defects in heart valves in valvular heart diseases, and provides an alternative to valve replacement. Without further specification, it refers to native heart valve repair, rather than repair of an artificial heart valve. Valvuloplasty is the widening of a stenotic valve using a balloon catheter. Types include: Commissurotomy of cardiac valves is called "valvulotomy". "Mitral valve repair" is mainly used to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. Aortic valve repair is a surgical procedure used to correct some aortic valve disorders as an
Mitral valve the left ventricle. It has two leaflets (or 'cusps'), an anteromedial leaflet, and a posterolateral leaftlet. The opening of the mitral valve is surrounded by a fibrous ring known as the "mitral annulus". The anterior cusp covers approximately two-thirds of the valve (imagine a crescent moon within the circle, where the crescent represents the posterior cusp). Although the anterior leaflet takes up a larger part of the ring and rises higher, the posterior leaflet has a larger surface area. The valve leaflets are prevented from prolapsing into the left atrium by the action of chordae tendineae. The chordae tendineae are
