Valve replacement may be recommended if your mitral valve is seriously damaged and cannot be repaired.
The decision about whether to repair or replace a valve is based on many things, including your general health, the condition of the damaged valve, the presence of other health conditions, and the expected benefits of surgery.

Mitral valve repair is usually preferred if your valve is suitable for reconstruction and the surgeon has the appropriate level of experience and surgical skill.
The advantages of mitral valve repair include the following:
It preserves your natural valve and its support (chordae tendineae). In general, the more of the natural valve that can be preserved during surgery, the better the results of the procedure.
