Abstract
The increasing use of cardiac implantable electronic devices (CIEDs) in pediatric and adolescent populations has led to a growing need for transvenous lead extraction (TLE). However, data on long-term outcomes remain limited. This study aimed to evaluate the efficacy and safety of TLE using mechanical rotational dilator sheaths in a pediatric cohort. This retrospective single-center study included 35 patients who underwent TLE between 2007 and 2025. Outcomes were compared between Evolution® (Cook Medical, Bloomington, IN, USA) and TightRail™ (Spectranetics/Philips, Colorado Springs, CO, USA) sheath systems. A total of 40 leads were extracted (mean age at extraction: 15.1 ± 4.2 years; 57% male). The most common indication for extraction was lead fracture/dysfunction (22/35–63%). Complete success with the procedure was achieved in 23 (66%) patients, and clinical success in 30 (86%). Major complications requiring surgery occurred in 5 (14%) patients, and minor complications in 2 (6%). Notably, all major complications occurred in patients with implantable cardioverter-defibrillator (ICD) leads (p = 0.013), including innominate vein injury, pericardial effusion, tricuspid entrapment, and cardiac perforation. A comparison of the Evolution® (n:20) and TightRail™ (n:15) sheath groups showed no statistically significant differences in complete procedural success (p = 0.603), clinical success (p = 0.604), or the incidence of major complications (p = 0.640). No procedure-related mortality was observed. TLE using mechanical rotational dilator sheaths in pediatric patients is feasible and provides acceptable clinical success rates. However, the risk of major complications remains considerable, particularly in patients with ICD leads. These findings highlight the importance of careful procedural planning and performing TLE in experienced centers with immediate surgical backup.
