[Constrictive pericarditis and rheumatoid arthritis].

Pericarditis is the commonest cardiac manifestation of rhumatoid arthritis. It is often clinically latent but it may evolve to constriction or less often to tamponade. The case presented is of a 60 year-old woman with a 5 year history of seropositive nodular rhumatoid arthritis in whom bilateral pleural effusions and constrictive pericarditis were observed after sudden termination of corticotherapy. She was treated successfully by pericardectomy. This complication is far from being exceptional (55 cases already reported). It justifies a systematic search for pericarditis in rhumatoid arthritis, especially by echocardiography.
