- What is Mitral Valve Prolapse?

- QUESTION: Can you tell me about mitral valve prolapse?

-
- ANSWER: Mitral valve prolapse is a condition in which the mitral valve in the
- heart has slipped out of its normal position. Although it sounds ominous,
- mitral valve prolapse is rather common and is seen in 5% of the population.
- It varies between a condition that no one, including a physician, notices to
- serious conditions causing physical symptoms that include lightheadedness and
- fainting.
- The mitral valve helps control the flow of blood between the left atrium
- and left ventricle in the heart, preventing blood from flowing back into the
- atrium rather than out through the aorta to the body. In a mild case of
- prolapse, there may be no problem, but a severely prolapsed valve allows some
- blood to flow back into the atrium during each beat and impair circulation.
- The main symptom of mitral valve prolapse is a heart murmur, extra
- clicking or murmuring sounds during each heart beat. Other symptoms that have
- been linked to mitral valve prolapse include chest pain, shortness of breath,
- palpitations, anxiety, lightheadedness, and fainting. However, because mitral
- valve prolapse is not rare, these symptoms may be present and not due to the
- valve problem.
- If mitral valve prolapse is suspected, your physician may refer you to a
- cardiologist who will use an ultrasound technique called echocardiography to
- make a diagnosis. Treatment is usually prophylactic aimed at preventing
- infections or over exertion that could lead to strain. Many patients simply
- need reassurance that they don't have a more serious problem.
