A 59-year-old man with a pacemaker who was admitted for evaluation of fever was found to have a redundant loop of the ventricular lead and a vegetation attached to it. An FDG PET/CT revealed a focus ...of FDG uptake at the ventricular lead loop. Surgical extraction of the pacemaker device confirmed a Propionibacterium acnes pacemaker endocarditis. We hypothesize that the redundant loop of the ventricular lead induced a chronic mechanical stress both to the tricuspid valve and to the lead itself, facilitating the bacterial colonization of the lead.
