How does a prolapsed mytralvalve affect a person?

Dental prophylaxis: Mitral valve prolapse (mvp) is a minor variation of the structure of this heart valve. Mvp does not by itself usually cause any symptoms, but sometimes it is part of a syndrome that includes other symptoms, such as palpitations and back pain. People with mvp have increased chance of infection on the valve (endocarditis), and should take antibiotics before dental procedures (ask your doctor!).

Varies: This label has been applied a lot more after specialized imaging systems (Doppler echo) began finding it in normal people. MVP can be trivial (unimportant) with no health consequences. It can also be major with a failing valve that could lead to other heart problems.
