The femoral approach with the Needle's Eye Snare (NES) is often used for bailout after failure of the superior approach for transvenous lead extraction (TLE). The safety and efficacy of the NES as a first-line tool for TLE remain unclear. The medical records of patients who underwent TLE via the femoral approach utilizing the NES from May 2014 to June 2019 in Peking University People's Hospital were retrospectively reviewed. Nine hundred and eighty-five leads were extracted in 492 patients (369 men; mean age 72.8 ± 29.0 years). The median (range) number of leads extracted per patient was 2 (1-6). The mean indwelling time of all extracted leads was 112.6 ± 52.0 months. The complete procedure success rate, clinical success rate, and failure rate were 94.1% (463/492), 97.8% (481/492), and 1.1% (11/492), respectively. Major complications including death occurred in nine patients (1.9%), of whom eight developed cardiac tamponade. Among these eight patients, emergency pericardiocentesis followed by rescue surgical repair if necessary was successful in 6 (75.0%) and failed in 2 (25.0%). No significant differences were found in the clinical success rate or major complications rate between patients with pacemakers and implantable cardioverter defibrillators, or between patients with infected and uninfected leads. A femoral approach with the NES is safe and effective for TLE of both pacing and defibrillator leads and could be considered a first-line approach. Cardiac tamponade was the most frequent cardiovascular complication. A strategy of emergency pericardiocentesis followed by a rescue surgical approach seems to be reasonable technique to treat a cardiac tamponade.

Background: Management of cardiac perforation caused by the lead of a cardiac implantable electronic device (CIED) is currently unclear. This study evaluated the outcomes of transvenous lead extraction (TLE) in patients with cardiac perforation caused by a transvenous lead., Hypothesis: Removal of perforated lead by transvenous approach is safe and effective., Methods: The medical records of all patients diagnosed with cardiac perforation by a pacing or defibrillator lead in Peking University People's Hospital from January 2008 to January 2019 were reviewed. We included patients who were managed by TLE., Results: A total of 53 patients (30 men; mean age: 67 ± 15 years) with lead perforation managed by TLE were included. Most of the perforated leads (94.9%) were pacemaker leads. Forty-three leads (81.1%) were implanted within 1 year. Ten patients with a high risk of hemopericardium underwent percutaneous subxiphoid pericardial puncture prior to TLE. All 53 culprit leads were removed completely without major complications. Simple traction with or without a locking stylet was sufficient in 51 patients (96.2%). Forty-eight patients (90.6%) had a new active-fixation lead reimplanted. No patients showed evidence of new-onset or worsening pericardial effusion during the procedure and hospital stay. During a median follow-up time of 16 months, no recurrence of symptoms associated with lead perforation or CIED-related infection were reported., Conclusion: In most patients with lead perforation, TLE can be a safe and effective management approach., (© 2020 The Authors.
