What is mitral valve prolapse?
A person with mitral valve prolapse has abnormal movement of the mitral valve in the heart. A normal mitral valve allows blood to flow from the left atrium, into the left ventricle. The mitral valve closes to prevent the backflow of blood from the left ventricle into the left atrium. A prolapsed mitral valve may result in episodes of palpitations. Most cases of mitral valve prolapse are inherited.

What are the symptoms of mitral valve prolapse?
Symptoms of mitral valve prolapse include palpitations, anxiety, chest pain, difficulty breathing, faintness, and fatigue.

How does the doctor treat mitral valve prolapse?
About 75 percent of people with mitral valve prolapse do not require treatment, while 25 percent require treatment with medication. Treatment for mitral valve prolapse may include beta-blockers, aspirin therapy, and warfarin. Those with mitral valve prolapse require antibiotics prior to dental procedures, in order to prevent endocarditis.
