[Rheumatoid cardiopathy. Observations on a clinical case]

The occurrence of cardiac involvement in RA is frequent but cardiac lesions are observed more frequently at necroscopy than on clinical examination. The case of a RA patient with a serious mitral valves involvement is reported in which the histological examination of the bioptic tissue obtained during surgical valves replacement showed a typical rheumatoid granulomatous inflammation of the endocardium.
