Outcome of transvenous lead extraction in nonagenarians: A single-center retrospective study.

Abstract

Transvenous lead extraction (TLE) for cardiovascular implantable electronic device (CIED)-related infections has increased. The incidence of TLE in nonagenarians is low, with limited reports outlining the outcomes of this procedure. Therefore, in this study, we aimed to clarify the outcomes of TLE in nonagenarians. Patients with TLE treated at our hospital between 2014 and 2023 were retrospectively examined; patient characteristics, device type, indications, procedures, complications, and clinical data of nonagenarians were analyzed. Of 12 patients with 24 leads (active fixation lead, n=11; passive fixation lead, n=13) who underwent TLE, the indication for TLE was infection (pocket infection, n=8; sepsis, n=4). Methicillin-resistant Staphylococcus epidermidis was the most frequently identified causative agent (n=4). The median patient age was 91 years; five patients were female. The median lead dwell time was 9 years. Excimer laser sheath (16 leads), mechanical sheath (five leads), Evolution RL (one lead), and manual traction (two leads) were employed in TLE. The procedure was successful in all patients, and only one had a minor complication. Six patients required CIED re-implantation, and leadless pacemakers were selected for five patients. The 30-day mortality after TLE was 0%. TLE can be safely performed in nonagenarians. The decision to perform TLE should not be based on old age alone; the suitability of removing infected CIEDs should be determined based on each patient's condition.
