There are two possible surgery in a patient with mitral valve disease:

1.-Valve repair. Proper operation is returned by various surgical techniques:

  • Commissurotomy that is used when there is a narrowing of the valve (mitral stenosis), the occurrence of any possible merger and thickening of the leaflets (the plates that make up the valve). The surgeon opens the valve by cutting the edges of the leaflets in the place where they are merged.
  • Annuloplasty: In dilated ring implantation of a device on the ring’s mission fruncirlo primitive restoring its original size and shape veils getting clogged the middle of the mitral orifice.
  • Valve plasty: by a rupture or chordal elongation there is a part where the drain valve (mitral regurgitation). There are many techniques that can be applied in these cases but most often is resection of the posterior portion with a suture and reinforcing annulus.
  • Descaling, which is the removal of calcium deposits on the leaflets. After removing the calcium, the leaflets can close properly.
  • Patching biological material, when the surgeon covers the holes or tears in the leaflets with pericardium of a patient or animal.

2.-Valve replacement. When the valve is severely damaged it must be replaced by a prosthesis. It is also often replace the valve when the patient’s condition is critical or when failed a previous repair.


Two types of prostheses are used in valve replacement:

  • Mechanical valves, normally made ​​of materials such as carbon or metal. Mechanical valves are rugged and durable. As the blood usually stick to mechanical valves and form clots, patients with these valves must take blood thinners (anticoagulants) for the rest of his life.
  • Biological valves, which are made of animal tissue. Patients with biological valves usually do not need chronic anticoagulation. However, these valves deteriorate over time and may need to be replaced approximately every 10 years. Biological valves wear out more quickly in children and young adults, so it is used most often in the elderly.

All doubts about the best type of prosthesis for you have to be resolved by your surgeon.
