Post-mortem study of the association between cardiac iron and fibrosis in transfusion dependent anaemia

Replacement fibrosis has been reported as causative of heart failure in siderotic cardiomyopathy in historical reports, but these findings do not accord with the reversible nature of siderotic heart failure achievable with intensive iron chelation.
