What to expect if I have Mitral regurgitation  (Outlook/Prognosis)?
How well a patient does depends on the cause and severity of the valve leakage. Milder forms may become a chronic condition.
Acute mitral regurgitation can rarely be controlled with medications. Surgery is usually needed to repair or replace the mitral valve.
Abnormal heart rhythms associated with acute mitral regurgitation can sometimes be deadly. </s>
