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

heart. Your doctor may want you to have a test called an echocardiogram to check for 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.
