Safety and effectiveness of transvenous lead extraction in elderly patients.

Background: There is a considerable controversy regarding safety of transvenous lead extraction (TLE) in elderly patients due to their potentially worse general condition, more concomitant diseases, more difficult sedation or analgesia. Moreover, the present experience is not relevant. The aim of the study was the comparison of safety and feasibility of TLE in elderly and middle-aged patients.

Methods: We have extracted an ingrown pacemaker (PM)/implantable cardioverter-defibrillator (ICD) leads from 1,060 adult patients (21-70 years) and 192 octogenarians (mean age 83.4 ± 3.1 years) using standard mechanical systems within the last 7 years. We compared effectiveness and complications of the TLE procedures in the two mentioned groups of patients.

Results: There were more women in octogenarians referred for TLE (45.3% vs. 36.9%). In addition, more pocket infections (37.0% vs. 24.5%), less non-infective indications for PM (46.9% vs. 57.7%) and ICD systems (7.3% vs. 28.8%) TLE were observed in this group. Leads body dwelling time was similar (76.4 ± 56.8 vs. 83.5 ± 63.0) in both groups. Procedure efficacy (full radiological success 97.4% vs. 94.6%, partial radiological success 2.6% vs. 4.34%), safety measures (major complications 1.6% vs. 1.51%, minor complications 1.0% vs. 1.9%) were similar in both compared groups.

Conclusions: Old age does not influence TLE effectiveness. Therefore, TLE can be safely and successfully performed in octogenarians.
