title: Successful reversal by chelation therapy of congestive cardiomyopathy due to iron overload.
abstract: A patient who developed severe iron overload cardiomyopathy is described. Venesection could not be performed because the patient had chronic anemia. Deferoxamine mesylate, a chelating agent, was administered daily for more than 2 years and produced significant improvement in ventricular function which was associated with a biopsy-proven decrease in myocardial iron stores. This is the first reported case in which a severe cardiomyopathy due to iron overload was reversed by chelation therapy alone.
