Cardiac failure is the major cause of death in patients with thalassemia and chronic blood transfusion-related iron overload. The treatment of thalassemia has been revolutionized over the past decade with the implementation of cardiac MRI based assessment of iron overload. This has enabled detection of cardiac iron overload prior to symptomatic heart failure and now allows for timely therapy which has resulted in a substantial decrease in mortality. However, currently implemented MR imaging techniques assess for iron content only and not for iron related diffuse fibrosis which play a role in iron related heart failure. Histopathologic studies indicate that patients with iron overload have diffuse interstitial fibrosis. Quantitative MR techniques have shown that patients with various cardiomyopathies demonstrate diffuse myocardial fibrosis and that these changes correlate with changes in cardiac function. The investigators propose that quantitative cardiac MRI for assessment of diffuse myocardial fibrosis can further improve our ability to detect early damage to the myocardium and prevent morbidity and mortality from cardiac iron overload. Detection of fibrosis in patients with thalassemia may allow for earlier identification of cardiomyopathy when compared to other techniques in clinical use including T2\* analysis. Identification of fibrosis could affect patient management as it would allow for tailoring of iron chelation therapy and may lead to better understanding of the disease processes contributing to heart failure and arrhythmia in these patients.
