Background: During transvenous lead extraction (TLE), a GlideLight laser sheath (Philips) cannot always be advanced over the lead, and crossover to the Evolution system (i.e., an Evolution RL sheath or Evolution Shortie RL sheath [Cook Medical]) is required. We aimed to determine the associated factors and outcomes of such device crossover. Methods: This observational study included 112 patients who underwent TLE. The patients were divided into crossover and non‐crossover groups. Outcomes and associated factors of crossover were evaluated. Results: Overall, 57 (50.9%) patients required crossover to the Evolution system (crossover group), whereas 55 (49.1%) patients did not require crossover (non‐crossover group). Clinical success rate was similar between the two groups (98.3% vs. 100%; p = 1.00). No major intraprocedural complications related to powered sheaths occurred. Multivariate logistic regression analysis results showed that dwell time of the oldest extracted lead (per year) (odds ratio [OR]: 1.18, 95% confidence interval [CI]: 1.02–1.36; p =.026), number of leads extracted per procedure (OR: 7.23, 95% CI: 1.74–29.99; p =.007), and use of a femoral approach (OR: 21.09, 95% CI: 2.33–190.67; p =.007) were associated factors of crossover. The cutoff for crossover was 7.7 years from the implant (sensitivity 90.5%, specificity 64.9%, area under the curve 0.80). Conclusions: Both groups showed a high rate of clinical success. Switching to the Evolution system may facilitate a safe and effective TLE when a laser sheath does not advance despite laser activation. [ABSTRACT FROM AUTHOR]
