Highlights the risk of acute bacterial endocarditis associated with permanent transvenous cardiac pacemakers, potentially seeded by distant infections.
Suggests pacemaker leads as potential nidus for endocarditis from distant infections; hypothesis-generating and should not yet change practice.
To our knowledge, the first case of acute bacterial endocarditis in a patient with a permanent pervenous cardiac pacemaker occurred on the mural endocardium of the right atrium along the course of the pacemaker catheter. It is suggested that bacteremia, probably originating from a sacral decubitus ulcer, resulted in implantation of organisms on the damaged atrial endocardium with subsequent septic embolization.
