Deskripsi
<i>Background</i>: Atrial fibrillation is the most common arrhythmia and has been described as driver of cardiovascular morbidity and risk factor for cardiac device-related complications, as well as in transvenous lead extraction (TLE). <i>Objectives</i>: Aim of this study was to characterize the procedural outcome and risk-factors of patients with atrial fibrillation (AF) undergoing TLE. <i>Methods</i>: We performed a subgroup analysis of all AF patients in the GALLERY (GermAn Laser Lead Extraction RegistrY) database. Predictors for all-cause mortality were assessed. <i>Results</i>: A total number of 510 patients with AF were identified with a mean age of 74.0 ± 10.3 years. Systemic infection (38.4%) was the leading cause for TLE, followed by local infection (37.5%) and lead dysfunction (20.4%). Most of the patients (45.9%) presented with pacemaker systems to be extracted. The total number of leads was 1181 with a 2.3 ± 0.96 leads/patient. Clinical procedural success was achieved in 97.1%. Occurrence of major complications was 1.8% with a procedure-related mortality of 1.0%. All-cause mortality was high with 5.9% and septic shock being the most common cause. Systemic device infection (OR: 49.73; 95% CI: 6.56–377.09, <i>p</i> < 0.001), chronic kidney disease (CKD; OR: 2.67; 95% CI: 1.01–7.03, <i>p</i> = 0.048) and a body mass index < 21 kg/m<sup>2</sup> (OR: 6.6; 95% CI: 1.68–25.87, <i>p</i> = 0.007) were identified as independent predictors for all-cause mortality. <i>Conclusions</i>: TLE in AF patients is effective and safe, but in patients with systemic infection the mortality due to septic shock is high. Systemic infection, CKD and body mass index <21 kg/m<sup>2</sup> are risk factors for death in patient with AF undergoing TLE.
