[Removal of an endocavitary electrode with cardiopulmonary bypass for septicemia associated with right atrial thrombosis. Report of a case (author's transl)].

A case of staphylococcus epidermidis endocarditis associated with a right atrial thrombosis around a pacemaker electrode is presented. Stuce the antibiotic therapy had proved uneffective, the electrode had to be removed with cardiopulmonary bypass; the infection was subsequently eliminated. When a foreign body cannot be removed by closed techniques, open heart surgery with cardiopulmonary bypass may be necessary.
