Heart Valve Problems: Mitral Valve Prolapse

Choose a preferred language

Mitral valve prolapse is the most common heart valve problem. With this condition, the valve that separates the left atrium and left ventricle doesn’t open and close as it should. Extra tissue in the valve can stop it from closing correctly. This can make the valve leaky.

Most cases of mitral valve prolapse aren't serious. Usually, only a small amount of blood leaks backward. This doesn't cause problems and doesn't need treatment. But sometimes a larger amount of blood can leak backward. This can lead to a serious problem, as the blood that leaks backward must be pumped twice. Over time, this takes a toll on the heart. You may need surgery to fix the valve if the heart starts to function poorly.

Symptoms of mitral valve prolapse

Mitral valve prolapse may not cause symptoms. If you do have symptoms, they may include:

  • Mild chest pain

  • Pounding or racing heart (palpitations)

  • Shortness of breath

  • Trouble breathing with activity

  • Fatigue

  • Migraine headaches

  • Fainting


Possible causes

Mitral valve prolapse is often present from birth. But some people can develop it later in life. In some cases, the condition is passed down from your parents (inherited).


Treating mitral valve prolapse

Most people with mitral valve prolapse have mild disease that doesn't get worse. It doesn't need to be treated. But sometimes the valves get more stretched out over time and can cause symptoms. Medicines can help ease symptoms.

Your healthcare provider may ask you to come in from time to time for tests to check your heart valve and to be sure the problem hasn’t gotten worse. In severe cases, surgery to fix or replace the valve may be needed.

Heart Valve Problems: Mitral Insufficiency

Mitral insufficiency means your mitral valve has problems closing, letting blood leak back through the valve. Mild cases of mitral insufficiency, when a small amount of blood leaks, rarely lead to problems. But severe cases can cause damage to the ventricle and heart muscle.
