A patient is described in whom severe prosthetic valvular stenosis developed ten months after mitral valve replacement with an Angell-Shiley porcine heterograft. At emergency operation, calcification of the prosthesis was revealed. Early calcification and stenosis of a porcine heterograft valve is a life-threatening complication that must be recognized promptly and treated by emergency valve replacement.
