Infections in Cardiac Implantable Electronic Devices: Diagnosis and Management in a Referral Center.

Introduction And Objectives: Infections in cardiac implantable electronic devices are increasing due to the expansion of the indications of these devices. The management of some aspects is controversial. Here, we report our broad experience.

Methods: Between 1985 and 2015, 325 infections (196 local and 129 systemic) were registered; 28.5% of them were referred from other centers: 229 pacemakers, 69 implantable cardioverter-defibrillators, and 27 patients with cardiac resynchronization therapy. The follow-up was at least 1 year after hospital discharge.

Results: Percutaneous traction (PCT) was the most frequent procedure (n=280) in local (n=166) and systemic infections (n=114), with complete extraction of the system in 82.5% of the patients, clinical success in 89%, and few complications (2 deaths attributable to the technique). Overall mortality was 1% in local infections and 8% in systemic infections. After 212 complete PCT, a new device was placed in 209: of these, a contralateral system was implanted in the same procedure in 152 (73%) and in a second procedure in 57, with no differences in relapses (2 in the 1-stage procedure, and 1 in the 2-stage procedure).

Conclusions: Percutaneous traction in experienced hands has good results with very few complications. It is possible to perform contralateral implantation of the new device on the same day without increasing the risk of relapse.
