Mitral Valve Prolapse - Topic Overview
What is mitral valve prolapse?
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. But the valve
bulges backward a little. It looks like a tiny parachute or balloon as it
bulges. (See a picture of

Mitral valve prolapse is the most common heart valve problem. It is more common in people who have a family history of this problem.
Is mitral valve prolapse a serious heart problem?

mitral valve regurgitation. The heart then has to work
harder to pump this extra blood. Over time, this can damage the heart.
