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.
Watch an animation of mitral valve regurgitation. A leaking mitral valve allows blood to flow in two directions during the contraction. Some blood flows from the ventricle through the aortic valve â as it should â and some blood flows back into the atrium.atch an animation of mitral valve regurgitation.
