Introduction: Cardiovascular implantable electronic device (CIED) infection contributes to a significant clinical and financial burden. We sought to assess CIED postimplant infection rates and the effect of different treatment modalities on reinfection over a long-term follow-up. Methods: We retrospectively analyzed CIED recipients presenting with complications during 2010–2019 at our center. Data related to the different management modalities used as per the discretion of treating physician, were collected and patients were followed up telephonically. Results: A total of 3394 patients underwent CIED implantation of which 122 (3.5%) patients developing complications were included in the study. Mean age of the patients was 66.4 ± 12.5 years. Single-chamber ventricular pacing (VVI), dual-chamber (DDD) pacing, and biventricular pacing were seen in 68 (56.2%), 51 (41%), and 3 (2.8%) patients, respectively. CIED infection was seen in 61 patients (1.8%). Strategies used for CIED infection management included: new device implantation on contralateral side (n = 34; 55.7%), old device repositioning on same side (n = 14; 22.8%), antibiotic therapy alone (n = 5; 8.5%), resterilized device implantation on contralateral side (n = 3; 4.9%), epicardial lead placement (n = 3; 4.9%), and permanent device removal (n = 2; 3.3%). The CIED reinfection rates for the above strategies were 2.9%, 71.4%, 80%, 100%, 0% and 0%, respectively. Conclusion: Multiple strategies are being used in real-world practice for the management of CIED infection. Previously advocated strategy of reimplanting resterilized CIED is associated with high recurrence rates. The best practice still remains to implant a new device on the contralateral side post extraction of infected hardware.
