My cardiologist said i had a prolapsed mitro valve. what does this mean?

Mitral valve prolaps: Mitral valve prolapse refers to a condition where the mitral valve leaflets (1 out of 4 valves in our heart) is mxyomatous, redundant and "billows" back, if you will, like a parachute into the left atrium during normal mitral valve closure. Because of its overdiagnosis in years past, the American society of Echocardiography, has come up with strict echo criteria for it. Check with your MD.
