Abstract

We report a case of 48 years old women with a 8 years history of rheumatoid arthritis and severe articular deformation treated during the last 6 months by prednisone (5 mg daily) and chloroquine (200 mg daily), admitted in the emergency room because of syncope. The electrocardiogram showed a complete atrioventricular block. Transesophageal echocardiography was performed and revealed an hyperechogenic mass (6 x 2.5 mm) in the interventricular septum probably related to a fibrous rheumatoid nodule. This potentially explain the atrioventricular block by infiltration of the conduction pathways. A permanent double chamber pacemaker was inserted. The chloroquine, another factor of conduction disturbances was not incriminated in this case. The conduction disturbances should be systematically detected in case of severe rheumatoid arthritis. Therefore, every patient must be submitted to a transthoracic echocardiography. Transesophageal echocardiography may be helpful to detect rheumatoid nodule.
