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 making this decision, you and your doctor need to consider:
Your symptoms and the area
of your mitral valve determine how severe your mitral stenosis is: the smaller
the area, the lower the volume of blood that is able to pass through it, and

atrium and left ventricle, as well as the blood pressure in your lungs, is also
used to assess severity.

The advantages of mitral valve repair are that it:
The disadvantages of mitral valve repair are that:
A balloon valvotomy is typically preferred over mitral
commissurotomy as long as the doctor is experienced with the procedure. The two procedures have similar rates of success. A balloon valvotomy is a minimally invasive catheter procedure. A commissurotomy repair is typically an open-heart surgery using a heart-lung bypass machine.
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.
