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 is . Microscopically, there is no evidence of an annular structure anteriorly, where the mitral valve leaflet is contiguous with the posterior aortic root. During left ventricular diastole, after the pressure drops in the left ventricle due to relaxation of the ventricular myocardium, the mitral valve opens, and blood travels from the left atrium to the left ventricle. About 70 to 80% of the blood that travels across the mitral valve occurs during the "early filling phase" of the left ventricle. This early filling phase is due to active relaxation of the ventricular myocardium, causing a pressure gradient that allows
