Picture of a normal mitral valve

In a normal heart, the two mitral valve flaps close completely, and stay closed, when blood is pumped out of the heart to the body.

Picture of a prolapsed mitral valve

When you have mitral valve prolapse, the valve closes after blood flows through. But the valve flaps bulge backward a little when blood is pumped out of the heart. When the valve bulges, it looks like a tiny parachute or balloon.
