[Constrictive pericarditis caused by carbergoline].

A 72-year-old male with paralysis agitans presented with symptoms and findings of constrictive pericarditis (CP). One year prior, he had a minor lateral MI. The patient had been treated with cabergoline for four years. At pericardiectomy, a thickened pericardium of 1-1,5 cm encased the right side of the heart. The pericardium was normal in the infarction area. Dopamine agonists pergolide and cabergoline for treatment of Parkinson s disease have been associated with development of CP. The absence of pericardial thickening in the infarction area suggests cabergoline as a probable cause.
