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 about 20% to the volume in the left ventricle prior to ventricular systole, and is known as the "atrial kick". The mitral annulus changes in shape and size during the cardiac cycle. It is smaller at the end of atrial systole due to the contraction of the left atrium around it, like a sphincter. This reduction in annulus size at the end of atrial systole may be important for the proper coapting of the leaflets of the mitral valve when the left ventricle contracts and pumps blood. Leaking valves can be corrected by mitral valve annuloplasty, a common surgical procedure
