title: Early bioprosthesis calcification in an octogenarian.
abstract: Pericardial valves have been advocated for use in the older age group of patients as they avoid the need for anticoagulation and are less liable to calcification than they are in the young. We report here a case of early valve calcification in a Sorin pericardial valve in the aortic position.
