[Tight mitral stenosis caused by calcifications of the ring extending to the valves]

Three years after valve replacement for Monckeberg type aortic stenosis, a tight and poorly tolerated tight mitral stenosis is observed, secondary to massive calcifications of the ring extending to the valves. The diagnosis is made with Doppler sonography and hemodynamic examination. Excision of the calcifications is particularly difficult. An early death occurs. Calcifications of the mitral ring extending to the valves, either isolated or mainly associated with a calcified aortic stenosis, may be complicated by mitral stenosis. The latter, usually moderate, may be tight and require surgical treatment, of severe prognosis.
