[Infectious endocarditis of the tricuspid valve in patients with endocardial pacemakers].

Right heart endocarditis in patients with permanent cardiac pacing catheters is uncommon but not an exceptionally rare complication. Two dimensional echocardiography provides diagnostic and prognostic information. The authors report two cases which illustrate the fact that many workers recommend explanation of the pacing catheter and that tricuspidectomy with or without valve replacement may sometimes be necessary.
