Myocardial siderosis due to hemochromatosis in an individual with hypertrophic cardiomyopathy.
A patient with hypertrophic cardiomyopathy (HCM) and transfusion-dependent sideroblastic anemia, who presented with decompensated heart failure, is described. The present case demonstrates the usefulness of cardiac magnetic resonance imaging as a noninvasive imaging modality to assess the etiology of new systolic dysfunction in the setting of HCM. Cardiac magnetic resonance imaging is able to differentiate between the dilated 'burned-out' phase of HCM and a concomitant dilated cardiomyopathy secondary to myocarditis or hemosiderosis.
