Mitral Valve Stenosis: Repair or Replacement
If you have mitral valve stenosis and you need surgery to treat it, you have a choice of repairing the valve or replacing it. Three things play a role in this decision: the severity of your mitral valve stenosis, the possibility that it will get worse, and the risks of surgery.

When is mitral valve replacement recommended?
Valve replacement surgery might be done if the valve is damaged beyond repair.
This surgery is a major, open-heart surgery that puts a lot of stress on your body. It involves the risks associated with a major surgery. The exact risks of mitral valve surgery vary depending on the person's specific condition and general health prior to surgery. Younger, healthy people have a lower risk of problems. Older people with other health problems have a higher risk.
