Abstract

Background: Device complications, such as infection or lead dysfunction necessitating transvenous lead extraction (TLE) are continuously rising amongst patients with transvenous implantable-cardioverter-defibrillator (ICD).

Objectives: Aim of this study was to characterize the procedural outcome and risk-factors of patients with indwelling 1- and 2-chamber ICD undergoing TLE.

Methods: We conducted a subgroup analysis of all ICD patients in the GALLERY (GermAn Laser Lead Extraction RegistrY) database. Predictors for procedural failure and all-cause mortality were assessed.

Results: We identified 842 patients with an ICD undergoing TLE with the mean age of 62.8 ± 13.8 years. A total number of 1610 leads were treated with lead dysfunction (48.5%) as leading indication for extraction, followed by device-related infection (45.4%). Lead-per-patient ratio was 1.91 ± 0.88 and 60.0% of patients had dual-coil defibrillator leads. Additional extraction tools, such as mechanical rotating dilator sheaths and snares were utilized in 6.5% of cases. Overall procedural complications occurred in 4.3% with 2.0% major complications and a procedure-related mortality of 0.8%. Clinical success rate was 97.9%. All-cause in-hospital mortality was 3.4%, with sepsis being the leading cause for mortality. Multivariate analysis revealed lead-age ≥10 years (OR:5.82, 95%CI:2.1-16.6; p = .001) as independent predictor for procedural failure. Systemic infection (OR:9.57, 95%CI:2.2-42.4; p < .001) and procedural complications (OR:8.0, 95%CI:2.8-23.3; p < .001) were identified as risk factors for all-cause mortality.

Conclusions: TLE is safe and efficacious in patients with 1- and 2-chamber ICD. Although lead dysfunction is the leading indication for extraction, systemic device-related infection is the main driver of all-cause mortality for ICD patients undergoing TLE.
