title: Reversal of iron-induced dilated cardiomyopathy during therapy with deferasirox in beta-thalassemia.
abstract: A 15-year-old male with beta-thalassemia major developed dilated cardiomyopathy secondary to iron-overload (Z-scores of left ventricle (LV) dimensions >3, ejection fraction (EF) 33%). Treatment with deferoxamine was unsuccessful, presumably due to poor compliance. After 15 months of using deferasirox (DFX), LV end-diastolic dimension normalized (Z-scores <2), and EF improved to 58%. We conclude that treatment with DFX resulted in a reversal of iron-induced cardiomyopathy.
