Really asymptomatic prolapse of the mitral valve ? I have a congenital mitral valve prolapse and a heart murmur . As I started to feel dizzy , tired and with a slight chest pain, went to the cardiologist because I had read on www.mayoclinic.com that these symptoms could be due to a PVM

The mitral valve closes when the heart pumps to prevent blood flow does not return to the lungs. When the mitral valve does not close properly, one or two of the leaflets of the valve extend above the other foil . This is what is called mitral valve prolapse . In most cases, it is a harmless condition and patients often have to ignore it . Up to 10% of the population has some type of prolapse of the mitral valve, but usually does not affect them . Prolapse can lead to a situation where blood to leak backward through the valve. This is called mitral regurgitation. Mitral valves that present an abnormal structure may increase the risk of valve infection . An echocardiogram is often the best way to examine the abnormalities of the mitral valve. A heart murmur usually suggests some degree of regurgitation. Most patients with mitral valve prolapse have no symptoms and require no treatment .
