The goal of treatment is to control the symptoms. Emergency surgery is often necessary if acute regurgitation is severe, usually resulting from endocarditis , MI , or ruptured cordae. Antibiotics may be prescribed if there is a bacterial infection. Anti-arrhythmics may be needed to control irregular rhythms.
Vasodilators reduce the workload of the heart.
Digitalis may be used to strengthen heartbeat, and diuretics to remove excess fluid such as fluid in the lungs. The outcome varies and depends on underlying conditions and the severity of the acute regurgitation. Milder forms of acute MR may become a chronic condition. Please read it.
