BACKGROUND: The feasibility and safety of lead extraction of cardiac implantable electronic devices (CIEDs) in the elderly Asian population remain uncertain. We report the outcome and safety of transvenous excimer laser-assisted lead extraction of CIEDs in Japanese patients aged ≥80 years. METHODS: Consecutive 235 patients (age 67±15 years, 167 male) undergoing lead extraction of CIED with an excimer laser system (Philips, Andover, MA, USA) were included. RESULTS: Of 235 consecutive patients, 51 (22%) were ≥80 years (age 86±5 years, 14 were aged ≥90 years; 42 had pacemakers, 3 had implantable cardioverter defibrillators, and 6 had cardiac resynchronization therapy devices). The median implant duration was 110±95 months. Patients aged ≥80 years had lower body mass index (BMI, 20.7±3.1kg/m2 vs. 22.6±3.4kg/m2, p<0.001), higher incidence of CIED infection (98% vs. 63%, p<0.010), and longer duration of hospitalization (31±17 days vs. 24 ± 31 days, p<0.001) than patients aged <80 years. There were no differences between the age groups in the rate of complete retrieval (94.1% vs. 95.1%, p=0.726) and major complications, including cardiac tamponade and cardiogenic shock (2.0% vs. 2.7%, p=1.000). CONCLUSIONS: Excimer laser-assisted lead extraction was safe and feasible in the Japanese elderly population with low BMI, despite the high likelihood of procedural complications. Early removal of infected CIEDs should be performed without delay in elderly Asian populations.
