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.

General 
Valvuloplasty is the widening of a stenotic valve using a balloon catheter. Types include:
Aortic valvuloplasty in repair of a stenotic aortic valve
Mitral valvuloplasty in the correction of an uncomplicated mitral

Valvulotomy

Commissurotomy of cardiac valves is called valvulotomy.

By valve

Mitral valve repair

Mitral valve repair is mainly used to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve.

Aortic valve repair
Aortic valve repair is a surgical procedure used to correct some aortic valve disorders as an alternative to aortic valve replacement. Aortic valve repair is performed less often and is more technically difficult than mitral valve repair.
There are two surgical techniques of aortic-valve repair:
 The Reimplantation-Technique (David-Procedure)
 The Remodeling-Technique (Yacoub-Procedure)

Tricuspid valve repair
Tricuspid valve repair is used to correct tricuspid regurgitation.

History
The first two percutaneous ultrasound-guided fetal balloon valvuloplasties, a type of in utero surgery for severe aortic valve obstruction, were reported in 1991.
