    What is (are) Mitral Valve Prolapse ?
    ### Response:
    Mitral valve prolapse (MVP) is a condition in which the hearts mitral valve doesnt work well. The flaps of the valve are floppy and may not close tightly. These flaps normally help seal or open the valve.
                
Much of the time, MVP doesnt cause any problems.
