Abstract Objective To evaluate treatment strategies in cardiac implantable electronic device(CIED) infection. Methods The treatment strategies and prognosis of CIED infection were retrospectively analyzed in 1 817 cases implanted with CIED. Results CIED infection occurred in 16 cases (0.88%). Of them, 15cases(93.75%) had pacemaker pocket infection. Al the pacemaker pockets were debrided and irrigated with povidone-iodine. The original pacemaker was re-implanted between the pectoralis major and minor muscles in 9 cases, of them, re-infection of CIED occurred in 6 cases (66.7%). No infection occurred again in 12 cases with the pacemakers removed. 8 cases had pacemakers removed and pacing leads left in place. 4 cases had pacemakers removed and pacing leads extracted percutaneously. There was no death due to infection and lead extraction. The hospitalization time and hospital stay were 2.4±0.5 and 41±18days, respectively, in patients with CIED infection and 1.0±0.1 and 13± 3days in patients without CIED infection. Conclusion Removing CIED is the key to successful treatment of CIED infection. The lead left in place may not affect the prognosis if without lead-associated infection.
