Implantation of pacemakers and cardiac defibrillators is a life-saving treatment but can put our patients at risk of infections, increasing morbidity and mortality and prolonging hospitalization with a significant financial healthcare burden. A preventive strategy is crucial but, while several strategies such as administration of intravenous antibiotic therapy before implantation are well recognized, other uncertainties remain. The main gaps regard the use of periprocedural measures, including antibacterial envelope to prevent device infection, the appropriate management of antithrombotic therapy before and after device implantation and timing of device reimplantation. To address these issues, some important randomized clinical trials and a European Heart Rhythm Association consensus document have recently been published. The aim of this article is to review current knowledge on the management of infections in patients with cardiac implantable electronic devices to help not only electrophysiologists, but also physicians in their daily practice.
