Sex differences in long‐term outcomes following transvenous lead extraction.

Introduction: Transvenous lead extraction (TLE) is generally considered a safe procedure, albeit not without risks. While gender‐based disparities have been noted in short‐term outcomes following TLE, a notable gap exists in understanding the long‐term consequences of this procedure. The objective of this analysis was to investigate sex differences in both acute and long‐term outcomes among patients who underwent TLE at a tertiary referral center. Methods: In this retrospective cohort study, consecutive patients who underwent TLE between January 2014 and January 2016 were enrolled. The primary outcome comprised a composite of all‐cause mortality and need for repeated TLE procedures. Secondary outcomes included fluoroscopy time, lead extraction techniques, success rates, and major and minor complications. Results were compared between female and male cohorts. Results: The study population comprised 191 patients (median age, 70 years), 29 (15.2%) being women and 162 men (84.8%). Study groups had similar baseline characteristics. Complete procedural success was achieved in 189 out of 191 patients (99.0%), with no significant difference observed between the two groups (p =.17). No major complications were reported in the total cohort. However, there was a significantly higher incidence of minor complications in women compared to men (17.2% vs. 2.5%, p <.01). Following a median follow‐up of 6.5 years, the incidence of the primary composite outcome occurred similarly between the study groups (log‐rank p =.68). Conclusion: Women who underwent TLE exhibited a significantly higher incidence of minor acute intra‐ and peri‐procedural complications than men. However, no differences in long‐term outcomes between genders were observed. [ABSTRACT FROM AUTHOR]
