Mitral valve 
regurgitation:   In this condition, the flaps (leaflets) of the mitral valve weaken, causing blood to leak backward into the left atrium in the heart. If not treated, this can result in heart muscle damage. The most common cause of blood leakage is mitral valve prolapse, in which the leaflets bulge back into the left atrium as the heart contracts.
