Mitral Regurgitation


What you need to know about mitral regurgitation:

The mitral valve is between the left atrium and left ventricle of your heart. The left atrium pumps blood into your left ventricle. The mitral valve opens to direct blood from your left atrium to your left ventricle. It closes when your left ventricle pumps blood to your body. Mitral regurgitation is when blood flows backward through the mitral valve. This happens because the mitral valve does not close properly.

Signs and symptoms:

You may not have symptoms or you may have any of the following:

  • Weakness, dizziness, or fatigue
  • Shortness of breath that gets worse during activity
  • Chest pain or discomfort
  • Cough, especially when you lie down
  • A fast heartbeat or feeling your heartbeat flutter
  • Swollen feet or ankles

Call 911 for any of the following:

  • You have any of the following signs of a heart attack:
    • Squeezing, pressure, or pain in your chest that lasts longer than 5 minutes or returns
    • Discomfort or pain in your back, neck, jaw, stomach, or arm
    • Trouble breathing
    • Nausea or vomiting
    • Lightheadedness or a sudden cold sweat, especially with chest pain or trouble breathing

Risks of mitral regurgitation:

Mitral regurgitation may cause fluid to build up in your lungs. It may also cause an abnormal heartbeat. An abnormal heartbeat may increase your risk for blood clots. Mitral regurgitation may lead to heart failure if not treated.

Treatment for mitral regurgitation

may depend on your symptoms and how severe your condition is. Medicines may be given to lower your blood pressure, decrease stress on your heart, or remove extra fluid. Your mitral valve may be repaired or replaced if it causes severe symptoms. This may be done through open heart surgery or a heart catheterization.


  • Maintain a healthy weight. Being overweight can increase your risk for high blood pressure, diabetes, and coronary artery disease. These conditions can make your symptoms worse. Ask your healthcare provider how much you should weigh. Ask him to help you create a weight loss plan if you are overweight.
  • Do not smoke. Nicotine and other chemicals in cigarettes and cigars can cause lung and heart damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
  • Do not drink alcohol. Ask your cardiologist if it is safe for you to drink alcohol. Alcohol can increase your risk for high blood pressure, diabetes, and coronary artery disease.
  • Eat heart-healthy foods and limit sodium (salt). Eat more fresh fruits and vegetables. Eat fewer canned and processed foods. Replace butter and margarine with heart-healthy oils such as olive oil and canola oil. Other heart-healthy foods include walnuts, whole-grain breads, low-fat dairy products, beans, and lean meats. Fatty fish such as salmon and tuna are also heart healthy. Ask how much salt you can eat each day. Too much salt can cause fluid to build up in your body. This can increase stress on your heart.
  • Exercise as directed. Exercise can help keep your heart healthy. Ask your healthcare provider what activities are safe for you to do. The amount and type of exercise that is safe may depend on how severe your condition is.
  • Talk to your healthcare provider about pregnancy. If you are a woman and want to get pregnant, talk to your healthcare provider. You and your baby may need to be monitored by specialists during your pregnancy.
  • Ask your healthcare provider if you should take antibiotics before certain procedures. Some procedures may allow bacteria to get into your blood and travel to your heart. This can make your condition worse.

Follow up with your cardiologist as directed:

You may need to return for more tests to check your heart. Write down your questions so you remember to ask them during your visits.
