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 insufficiency of the regurgitant flow at the level of the valve. This is known as the regurgitant orifice area, and correlates with the size of the defect in the mitral valve. One particular echocardiographic technique used to measure the orifice area is measurement of the proximal isovelocity surface area (PISA). The flaw of using PISA to determine the mitral valve regurgitant orifice area is that it measures the flow at one moment in time in the cardiac cycle, which may not reflect the average performance of the regurgitant jet. The treatment of mitral insufficiency depends on the acuteness of the disease
