A leaky mitral valve, or mitral regurgitation, can develop when the valve flaps (called leaflets) do not close effectively. This can happen either because the valve flaps are scarred or defective, or because the heart has become enlarged, stretching the valve opening so much that the flaps no longer meet in the center.
Mitral regurgitation is where blood leaks back through the mitral valve in the heart as the valve does not close properly. This increases the pressure in the left atrium and in the blood vessels coming from the lungs. This may lead to various problems and symptoms, depending on the severity of the leak.itral valve prolapse. This is also called floppy mitral valve. In this condition the valve is slightly deformed and bulges back into the left atrium when the ventricle contracts. This can let a small amount of blood leak back into the left atrium. As many as 1 in 20 people have some degree of mitral valve prolapse.
