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 annuloplasty the cardiac cycle. These changes are primarily due to the dynamic motion of the surrounding mitral valve annulus, a collageneous structure which attaches the mitral leaflets and the left atrium to the ostium of the left ventricle and the aortic root. Throughout the cardiac cycle, the annulus undergoes a sphincter motion, narrowing down the orifice area during systole to facilitate coaptation of the two leaflets and widens during diastole to allow for easy diastolic filling of the left ventricle. This motion is further enhanced by a pronounced three-dimensional configuration during systole, the characteristic saddle shape. These changes throughout the cycle
