These women, ages 61, 72 and 74 years, receiving long-term pergolide therapy for Parkinson's disease or restless legs syndrome, had valvular abnormalities strikingly similar to those induced by fenfluramine, ergot derivatives, or carcinoid. All three had severe, unexplained tricuspid regurgitation; two had predominantly right-sided congestive heart failure; and two had moderate aortic and mitral valve regurgitation. Histology revealed surface fibroproliferative lesions with preserved underlying valve architecture. Carcinoid was excluded, and none of the patients had taken anorectic drugs or ergots other than pergolide.
