OBJECTIVES: This study sought to assess the impact of early versus delayed lead extraction in patients with an infected cardiovascular implantable electronic device (CIED). BACKGROUND: CIED infections are associated with poor outcomes. Prior studies have demonstrated improved survival with CIED extraction compared with antibiotic therapy alone. The impact of timing of CIED extraction has not been well characterized. METHODS: All infected CIED extraction cases at our medical center from 2006 to 2019 were reviewed. Patients were divided into 2 groups based on the presence of bacteremia or isolated pocket infection. We assessed the in-hospital morbidity and 1-year mortality for early versus delayed lead extraction, using hospitalization day 7 as cutoff. RESULTS: Of 233 patients who underwent CIED extraction, 127 patients had bacteremia and 106 patients had pocket infection. Delayed extraction (15.2 days) in bacteremic patients was associated with septic shock (odds ratio [OR]: 5.39; 95% confidence interval [CI]: 1.23 to 23.67; p = 0.026), acute kidney injury (OR: 5.61; 95% CI: 2.15 to 14.63; p < 0.001), respiratory failure (OR: 5.52; 95% CI: 1.25 to 24.41; p = 0.024), and decompensated heart failure (OR: 3.32; 95% CI: 1.10 to 10.05; p = 0.033). Locally infected patients with delayed extraction (10.7 days) were associated with acute kidney injury (OR: 3.45; 95% CI: 1.11 to 10.77; p = 0.033) and respiratory failure (OR: 10.29; 95% CI: 1.26 to 83.93; p = 0.030). Delayed CIED extraction in both groups was associated with increased 1-year mortality. CONCLUSIONS: Delayed infected CIED extraction is associated with worse outcomes. This underscores the importance of early detection and a strategy for prompt management including lead extraction.
