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.
1 Mitral valve prolapse: When the valve is closed, the leaflets bulge abnormally up, into the atrium. 2  Sometimes mitral valve prolapse causes mitral valve regurgitation. 3  If the prolapse is severe, the valve leaflets can become disconnected from tendons that stretch between the leaflets and the heart muscle.roblems with the mitral valve include: 1  Mitral stenosis: The leaflets are fused, are too thick, or there is some other structural defect in the valve leaflets. 2  Sometimes, mitral stenosis occurs as a result of surgery to repair an abnormal mitral valve.
