Myocardial calcification after orthotopic heart transplantation

Two cases with a remarkable similarity in their clinical and histopathologic findings are reported. Both cases involved myocardial calcification found in biopsy material obtained after orthotopic heart transplantation. Myocardial calcification after heart transplantation so far has been described in only one case in the medical literature and thus appears to be a rare entity. Its occurrence is associated with a certain constellation of clinical situations, which include repeated episodes of acute rejection, temporary uremia, periods of septicemia, alcoholism, and cyclosporine and/or steroid therapy.
