Clinical outcomes of transvenous lead extraction in octogenarians: a real-world propensity score-matched analysis

Background
Real-world evidence on procedural safety and clinical outcomes of transvenous lead extraction (TLE) in elderly patients, particularly Asian octogenarians, remains limited. This study aimed to evaluate procedural outcomes and complications of TLE in octogenarians.
Methods
Patients who underwent TLE between June 2016 and August 2025 were retrospectively analyzed. Clinical outcomes were compared between octogenarians and non-octogenarians before and after propensity score matching.
Results
Overall, 552 transvenous leads (median lead age, 8.1 years) were extracted from 380 patients (median age 67.0 years, 57.1% male). Octogenarians (n=57, 15%) had smaller body size and a higher prevalence of comorbidities. In the propensity score-matched populations, the primary composite outcome of clinical failure and major complications did not differ significantly between non-octogenarians and octogenarians (5.3% vs. 7.0%, P=0.908). Secondary outcomes were also comparable, including complete success (94.7% vs. 89.5%, P=0.341) and clinical success (96.5% vs. 93.0%, P=0.522). In multivariable analysis, octogenarian status was not associated with the primary outcome, whereas lead age ≥ 10 years independently increased risk of the primary outcome (adjusted odds ratio, 6.35; 95% confidence interval, 2.24–17.98; P<0.001). In subgroup analysis, female octogenarians showed a tendency toward lower procedural success and higher complication rates (complete success 97.8% vs. 82.8%, P=0.004; clinical success 97.8% vs. 86.2%, P=0.023; primary outcome 4.5% vs. 13.8%, P=0.142).
Conclusions
In this real-world data, TLE in octogenarians demonstrated procedural success and complication rates comparable to younger patients. Octogenarian status alone does not confer excess risk. However, female octogenarians may represent a vulnerable subgroup warranting further investigation.
