Reversible dilated cardiomyopathy associated with amphotericin B treatment.

We report two patients, who developed dilated cardiomyopathy and subsequent congestive heart failure after treatment with amphotericin B (AmB). The echocardiographic findings and the symptoms of heart failure resolved after the discontinuation of the drug. The clinical data from our cases and two similar cases reported in the literature suggest that the presence of other factors predisposing to cardiac dysfunction may facilitate the occurrence of this rare side effect.
