Successful treatment of refractory cardiac tamponade due to rheumatoid arthritis using pericardial drainage.

Rheumatoid pericarditis occurs in patients with rheumatoid arthritis (RA). However, cardiac tamponade due to rheumatoid pericarditis is rare; we describe a case of a 72-year-old man with a 6-year history of rheumatoid arthritis who developed rheumatoid pericarditis with recurrent cardiac tamponade. The patient experienced relapse of the cardiac tamponade despite treatment with pericardiocentesis.
