Transvenous lead extraction (TLE) is a well-established treatment option for patients with cardiac implantable electronic devices (CIED) complications. This study aims to evaluate the safety and efficacy of TLE in CIED infection and non-CIED infection patients. Consecutive patients who underwent TLE between 2016 and 2022 entered the EXTRACT Registry. Models of prediction were constructed for peri-procedural clinical and procedural success and the incidence of major complications, including death in 30 days. The registry enrolled 504 patients (mean age 66.6 ± 12.8 years, 65.7% male). Complete procedural success was achieved in 474 patients (94.0%) and clinical success in 492 patients (97.6%). The total number of major and minor complications was 16 (3.2%) and 51 (10%), respectively. Three patients (0.6%) died during the procedure. New York Heart Association class IV and C-reactive protein levels defined before the procedure were independent predictors of any major complication, including death in 30 days in CIED infection patients. The time since the last preceding procedure and platelet count before the procedure were independent predictors of any major complication, including death in 30 days in non-CIED infection patients. TLE is safe and successfully performed in most patients, with a low major complication rate. CIED infection patients do better regarding peri-procedural clinical success and complete procedural success. Still, CIED infection predicts higher 30-day mortality compared with non-CIED infection patients. Predictors of any major complication, including death in 30 days, differ between CIED infection and non-CIED infection patients.

Introduction: One of the most frequent cardiac implantable electronic device (CIED) implantation complications is lead dislodgement, especially in the older adult population. Little evidence is available about the influence of frailty on the risk of lead dislodgment after CIED implantation procedures; thus, the evaluation of frailty could be relevant for the course and safety of the implantation procedure, especially among the elderly with cardiovascular diseases. This study aimed to assess the risks and predictors of early lead dislodgement in the elderly population. Methods: Between 2008 and 2021, 14,293 patients underwent implantations. In 400 elderly patients, lead dislodgement was confirmed, and frailty was retrospectively calculated. Results: The most frequent dislodgement according to the lead position was that of the atrial lead (133; 33.3%). In the logistic regression, frailty (OR: 1.8196, 95% CI:1.4991–2.2086; p < 0.0001) and age (OR: 1.0315, 95% CI:1.0005–1.0634; p < 0.0461) were independent predictors of early dislodgement. In the female group, frailty (OR: 2.1185, 95% CI: 1.5530–2.8899; p < 0.0001) was an independent predictor of early dislodgement. Similarly, in the male group, frailty (OR: 1.6321, 95% CI:1.2725–2.0934; p < 0.0001) was an independent predictor of early dislodgement. Conclusion: Lead dislodgement often occurs in the elderly. Frailty in both men and women is a predictive factor of early lead dislodgment. Evaluating frailty may be an essential element of proper selection, especially in the elderly undergoing CIED procedures, and, consequently, it could help prevent further complications.

Aims: The application of conduction system pacing (CSP) in clinical practice is growing, and the need for lead extraction will also increase. The data on outcomes and safety of CSP lead extraction are limited. The aim of this study was to assess procedural outcomes and safety of CSP lead removal. Methods and results: Forty-seven patients from the EXTRACT Registry with the indication for CSP lead removal were enrolled in the study conducted at the Department of Electrocardiology in Katowice, Poland. Extraction technique, outcomes, safety, and complication were evaluated. Forty-three (91.5%) leads were successfully removed, and 41 (87.2%) were removed with traction only. The dwelling time of 28 extracted leads was longer than 1 year, and the oldest extracted lead was implanted for 89 months. Seven (14.9%) leads were removed from the left bundle branch (LBB) area and 36 from the His bundle (HB). Transient complete atrioventricular block occurred during the procedure in two patients. In 27 out of 31 attempts (87.1%), new CSP leads were implanted: nine (33.3%) HB pacing leads and 18 (66.7%) LBB area pacing leads. Conclusion: The CSP lead extraction is safe and feasible with a low complication rate and high rate of CSP lead reimplantation.

Background: The lead breakage (LB) during transvenous lead extraction (TLE) increases procedural complexity, increases the risk of complications, and decreases procedural efficiency. This study aimed to identify protective and risk factors for the breakage of cardiac electronic device leads during extraction. Methods: Data were sourced from the EXTRACT prospective registry for TLE procedures conducted between January 2016 and June 2025. A total of 702 consecutive TLE procedures involving 1375 leads were enrolled. Multivariate logistic regression was used to identify independent protective and risk factors and develop a model to predict the occurrence of LB during TLE. Results: In the analysed group, 56 (7.98%) of 702 TLE procedures were disrupted by the breakage of at least one lead. The model showed a lower lead breakage rate in procedures when an atrial lead was simultaneously extracted, a locking stylet was used, and when the procedure was conducted in older patients or those who had undergone prior cardiac surgery. Higher risk of LB was proven in the following cases: the extraction of leads implanted a long time ago; the extraction of VDD-type leads; the extraction of abandoned leads; extraction during a prolonged procedure. Occurrence of lead breakage may lead to pericardial effusion requiring intervention, acute kidney injury, or leaving remnants of the leads. Conclusions: Lead breakage is an underestimated procedural difficulty that can occur during transvenous lead extraction. In this study, several clinical and procedural variables were independently associated with lead breakage. Abandoned leads, VDD leads, and prolonged procedure time were associated with increased risk. In contrast, older age, use of a locking stylet, atrial lead extraction, prior cardiac surgery, and later year of implantation demonstrated independent protective associations.

Introduction: Bacterial multidrug resistance (MDR) drives treatment with expensive, toxic, or pharmacokinetically suboptimal antibiotics. Objectives: To assess the prevalence of MDR Gram-positive cocci among isolates from cardiac implantable electronic device (CIED) infections at a Polish reference center. Methods: Data come from the “EXTRACT” registry (ClinicalTrials.gov ID NCT05775783), which covers 702 transvenous lead extraction procedures. Blood samples and intraoperative swabs were collected from participants with CIED infection. Results: From 209 cases with isolated pocket infection (PI) (107, 51.2%) or systemic infections (102, 48.8%), 263 Gram-positive cocci were cultured. They were: coagulase-negative staphylococci (CoNS) (177, 67.3%), Staphylococcus aureus (62, 23.6%), enterococci (15, 5.7%), streptococci (8, 3.0%), and others (1, 0.4%). The highest MDR rate was among CoNS (46.9%). CoNS exhibited methicillin resistance (MR-CoNS) in 55.9% with co-resistance to macrolides (73.2%), lincosamides (51.0%), fluoroquinolones (56.1%), aminoglycosides (41.4%), tetracyclines (29.6%), and co-trimoxazole (29.3%). Resistance to daptomycin (5.3%) and linezolid (2.0%) in MR-CoNS was rare. The frequency of MDR S. aureus was 8.1%. Methicillin resistance in S. aureus (MRSA, 6.5%) co-occurred with resistance to macrolides/lincosamides and fluoroquinolones (100% for both) or linezolid (25.0%). All MDR staphylococci were vancomycin-susceptible. High-level aminoglycoside resistance (HLAR) in Enterococcus faecalis (53.8%) was accompanied by levofloxacin co-resistance (66.7%). Conversely, E. faecium HLAR (50.0%) strains showed 100.0% β-lactam resistance. Vancomycin-resistant enterococci (VRE) accounted for 6.7%; the VRE E. faecium strain was tigecycline- and linezolid-susceptible. Among viridans group streptococci, β-lactam and lincosamides resistance was common (40.0% for both), with 50.0% of co-resistance. Conclusions: Epidemiological data may improve the effectiveness of empirical antibiotic therapy for CIED-related infections.
