Reversible Cardiomyopathy After Epirubicin Administration

Anthracycline-containing chemotherapy can cause irreversible and progressive left ventricular dysfunction. Epirubicin, which is widely used for breast cancer chemotherapy, is an anthracycline that has less cardiac toxicity than doxorubicin. The present report describes the case of a 70-year-old woman with breast cancer who developed severe congestive heart failure and severe cardiac dysfunction at 6 weeks from epirubicin final administration. Left ventricular function gradually improved after intensive treatment for heart failure and recovered completely within 2 months. To the best of our knowledge, this is the first report to describe epirubicin-induced subacute reversible cardiotoxicity.
