Late doxorubicin cardiotoxicity.

The occurrence of late congestive heart failure (CHF) as the first clinical manifestation of doxorubicin-induced cardiac toxicity is unusual in children and very rare in adults. However, subclinical cardiac dysfunction is commonly detected in children years after treatment with doxorubicin containing regimens. We report a 58 year old woman who developed stage IV CHF 7 years after completion of doxorubicin treatment for carcinoma of the ovary. Occult cardiac dysfunction was first demonstrated by radionuclide angiography 6 years prior to the occurrence of the clinical manifestations. This unique course of the disease and the management of the CHF are discussed.
