Calcific pulmonic stenosis in adulthood: treatment by valve replacement (porcine xenograft) with postoperative hemodynamic evaluation.
Clinical and morphologic features are described in a 56-year-old man in whom severe, isolated pulmonic valve stenosis was treated by valve replacement with a porcine prosthesis. The calcific deposits were located on the ventricular aspect of the pulmonic valve, opposite the location (arterial aspect) of calcific deposits on stenotic aortic valves, and calcific deposits also were present in the tricuspid valve anulus.
