If heart failure develops from Mitral Stenosis, it can be treated with medications. For example, a mild diuretic may be prescribed to reduce the amount of blood and other fluids that accumulate in the lungs and body tissues.   

If mild, mitral stenosis is well tolerated without therapy. If the mitral valve is seriously impaired, a valve replacement may be performed (see animation). After this procedure, anticoagulants (blood-thinners) may be prescribed to prevent blood clots from forming.
