I was diagnosed with a billowing mitral valve. what does it mean and is it different than standard mvp?

Clear Sailing!!: Quote:"There is a gradation from the normal billowing during ventricular systole of mitral leaflet bodies to marked billowing. With advanced billowing or floppy leaflets, failure of leaflet edge apposition supervenes (true prolapse). This is functionally abnormal and allows mitral regurgitation." So, you are OK so far, just have it periodically checked per the advice of your doctor.
