Your mitral valve
controls blood flow on the left side of your heart. The valve opens and closes with
each heartbeat. It works like a one-way gate, letting blood flow from your upper heart
chamber to your lower chamber.
When you have mitral valve prolapse (MVP), the
valve closes after blood flows through. Blood flows normally through the valve. But
the valve bulges backward a little. It looks like a tiny parachute or balloon as it
Is mitral valve prolapse a serious heart
No. Mitral valve prolapse is not dangerous. It usually does not damage
your heart. You will probably not need treatment. You can live a normal, healthy life.
valve prolapse raises your risk of having a problem called mitral valve regurgitation. This problem happens
if the valve does not close tightly enough and blood leaks back (regurgitates) into
the upper chamber of the heart. The heart then has to work harder to pump this extra
Is mitral valve prolapse treated?
people who have mitral valve prolapse do not need treatment for it. A heart-healthy
lifestyle and regular exercise are recommended for most people.
What are the symptoms?
Most people do not have any symptoms. You may not
even know you have MVP until a doctor hears a "clicking" sound or a murmur when listening
to your heart. Your doctor may want you to have a test called an echocardiogram to check for mitral valve prolapse.
What causes mitral valve prolapse?
prolapse is caused by a physical change in the valve. Physical changes such as thickening
and abnormal shapes cause most of the cases of MVP.
What causes these physical
changes is not known. A valve problem may be passed down through family members.
