Acute right ventricular heart failure in a patient with renal cell carcinoma after interferon therapy.

Abstract

In a patient with diffuse pulmonary metastases of a renal cell carcinoma the development of severe pulmonary hypertension is described after reaching a complete remission during treatment with r-IFN-alpha 2c and rIFN-gamma. Rechallenge with interferon after the discovery of recurrent disease did not lead to deterioration of the cardiopulmonary condition. Possible causative mechanisms are discussed.
