Medicines do not prevent or correct the
damage to the heart caused by
mitral valve regurgitation (MR). In chronic regurgitation, they might be used in some people to reduce the severity of regurgitation. Or they might be used to treat complications of mitral regurgitation. In acute regurgitation, medicine is used as emergency treatment before surgery.
chronic MR, you probably won't need medicines unless you have symptoms.
chronic and severe MR who also have an enlarged, abnormally functioning
left ventricle may not benefit from mitral valve
surgery and are often treated with medicines to try to relieve their symptoms.
Depending on the severity of their MR, some older people may also be treated
with medicines because they may not be good candidates for surgery. That's because they are at greater risk for developing complications
during or following surgery.
Vasodilators. You might take these medicines if you have symptoms or high blood pressure or if your heart is not pumping blood as well as normal.
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.
Medicine after surgery. If you have surgery for mitral regurgitation, you will likely take a blood thinner. Blood thinners prevent blood clots. Blood thinners include antiplatelet medicine, such as aspirin, or anticoagulant medicine, such as warfarin. You may need to take this medicine for the rest of your life.
In acute MR, medicines are used in the hospital to
stabilize your condition until you can have surgery to replace or repair the
Vasodilators such as nitroprusside help reduce the
amount of blood flowing back into the left atrium.
Diuretics help reduce workload on the heart.
Medicines are used to prevent or treat complications of mitral regurgitation such as atrial fibrillation or heart failure. For more information, see the topics:
