Recurrent sepsis from retained endocardial electrode in children: successful removal with cardiopulmonary bypass.

Infection remains a significant problem in patients undergoing permanent cardiac pacemaker implantation, and removal of all components is usually required. The transvenous system carries minimal morbidity at implantation, but the development of infection is more life-threatening than in the epicardial system. Although the evolution of the tined porous endocardial lead reduced the incidence of wire displacement, the development of a serious infection is still a problem and may require major surgery for removal. We experienced this problem in a 15-month-old child who developed recurrent sepsis. Attempts at removal of the retained tined porous electrode through the neck incision proved dangerous and unsuccessful. Removal was carried out using cardiopulmonary bypass and infection was promptly controlled.
