Living with mitral valve prolapse, from the Harvard Heart Letter

Most people with mitral valve prolapse have no symptoms and no complications, need no treatment, and can expect to live as long as people without this common heart problem. But that doesn't mean it should be completely dismissed. Instead, it is a good idea to have it evaluated every three to five years and maintain a healthy lifestyle and regular exercise, reports the March 2009 issue of the Harvard Heart Letter.

The mitral valve acts as a one-way opening between the heart's left atrium and left ventricle. The valve's two doors, called leaflets, open when the left atrium contracts, pushing oxygen-rich blood from the lungs down into the left ventricle. As the left ventricle contracts, the mitral valve snaps shut. This prevents blood from surging backward into the left atrium, and directs it out to the body instead. In some people, the leaflets of the mitral valve don't fit together tightly, and they bulge or billow backward into the left atrium. This bulging is called prolapse.
