Efficacy and safety of the new TightRail™ mechanical sheath for transvenous lead extraction: Results of a French multicenter study.

Abstract

The aim of this study was to assess the safety and efficacy of the TightRail™ sheath for pacemaker/defibrillator transvenous lead extraction (TLE). Multicenter observational study including patients who underwent a TLE with the TightRail™ sheath in five French university hospitals from September 2014 to January 2020. Two hundred and twenty-fivepatients (76% males, 71 ± 12 years) underwent a TLE procedure with the TightRail™. A total of 438 leads were extracted using the TightRail™, and the mean age of the extracted leads was 128 ± 85 months; of these, 344 (79%) were pacing leads and 94 (21%) were implantable cardioverter defibrillator leads. The overall clinical success of the extraction procedures was 93%. Overall, 410 of the 438 leads (95%) were extracted (complete or incomplete removal). After multilevel mixed-effects logistic regression model, we found that lead age(odds ratio[OR], 95% confidence interval [CI]for a 1 year increase: 1.11 [1.07-1.15], p < .001) and number of leads extracted (OR, 95% CI: 2.09 [1.50-2.96], p < .001) were the two independent factors associated with complete lead removal failure. Finally, there were 7(3%) cases of major complications but no per-procedural death. This is the first large-scale survey assessing the efficacy and safety profile of the Tightrail™ mechanical sheath. The clinical success rate was 93%, and the lead removal failure was dependent on the age and number of leads. We show a satisfactory safety profile in this cohort of patients from primarily low-volume centers with older leads.
