Porcine valves are generally known to have a limited durability. The case is reported of a 35-year-old male patient who underwent mitral valve replacement with a 28 mm Liotta porcine bioprosthesis. At reoperation 21 years later, the bioprosthesis was replaced (uneventfully) with a second porcine bioprosthesis. Pathological and X-radiographic examinations of the excised valve demonstrated focal calcification of the leaflets, confirming the long-term durability of the Liotta porcine bioprosthesis.
