An Alternative to Transvenous Lead Extraction in Selected Patients with CIED Infections—A Retrospective Outcome Study

Cardiac implantable electronic device (CIED) implants are rising in an older, more co-morbid population. The prevalence of CIED infection ranges from 1–4%. Whilst complete extraction of all transvenous hardware is recommended for infected, eroded, or pre-eroding CIEDs, this approach is not without risk and may be unacceptable to some patients. Long-term data on a more conservative strategy is lacking. We report on our experience of conservative management with pocket revision as a primary strategy in carefully selected patients. Method: A retrospective review of all CIED revision procedures was undertaken at a large tertiary center, over a 7-year period, with a mean follow-up timeframe of 39 months. Results: A total of 86 patients underwent 96 revision procedures; 7 patients required further revisions and 13 went on to undergo CIED extraction by the end of the follow-up period. The overall rate of mortality at 12 months was 8.1%, increasing to 24.4% at the end of the follow-up period. Conclusion: Our data provide important outcome information on an alternative strategy to lead extraction in carefully selected patients where the risk of extraction is perceived to be unacceptable. The absence of systemic infection appears to predict better outcomes than previously reported, and over two-thirds of patients remained complication-free at 12 months.
