Symptoms
For most people with
mitral valve prolapse (MVP), the effect on the heart
is minor, and they have no symptoms.
Some people with MVP have
shortness of breath, chest pain, or heart
palpitations. But it is not clear that these symptoms
are caused by MVP. Doctors don't know exactly why some people have these
symptoms.
In rare cases, people who develop severe
mitral valve regurgitation may have symptoms of
heart failure (such as shortness of breath, fluid
buildup, and fatigue) or symptoms of
arrhythmia (such as lightheadedness and
weakness).
There are
other conditions that have symptoms similar to MVP,
including other heart valve conditions that cause similar abnormal heart
sounds.
