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. Also, digitalis can make the heart beat more vigorously and control irregularities in its rhythm.
The retention of fluids can also be treated by following a diet that is low in salt, which encourages the body to retain water. Other behavioral steps that help mitigate the affects of Mitral Stenosis include moderate exercise and the avoidance of caffeine, smoking, stress, and excessive alcohol. Also, it is important to avoid or immediately treat blood infections that could attack the heart's valves.
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.
