Mitral Valve Regurgitation - Medications

Medicines do not prevent or correct the damage to the heart caused by mitral valve regurgitation (MR). For chronic regurgitation, they might be used to treat complications of mitral regurgitation. They might be used to help treat the heart problem that has caused secondary MR. In acute regurgitation, medicine is used as emergency treatment before surgery.

Chronic regurgitation

In chronic MR, you may take medicine if you have symptoms and a low ejection fraction. You may take medicine to treat heart failure.

Medicine after surgery

Antibiotics. If you have an artificial valve, you may need to take antibiotics before you have certain dental or surgical procedures. The antibiotics help prevent an infection in your heart called endocarditis. You will likely take antibiotics after surgery to repair or replace a valve. If you have had rheumatic fever, you may take antibiotics to avoid getting it again.

Blood thinners. Blood thinners prevent blood clots after surgery. Blood thinners include antiplatelet medicine, such as aspirin, or anticoagulant medicine, such as warfarin. If you have an artificial heart valve, you may need to take this medicine for the rest of your life.

Acute regurgitation

In acute MR, medicines are used in the hospital to stabilize your condition until you can have surgery to replace or repair the valve.


Medicines are used to prevent or treat complications of mitral regurgitation such as atrial fibrillation or heart failure. For more information, see the topics:
