Unique Extraction of a Fractured Pacemaker Lead Adhered to the Spermatic Vein

Transvenous lead extraction has been increasingly recognized as a safe and effective method of lead extraction, but there are only few references for extracting leads migrating outside the heart. We present a successful extraction of a fractured pacemaker lead from the spermatic vein using several approaches and multiple tools.

Transfemoral extraction of pacemaker and implantable cardioverter defibrillator leads using Needle's Eye Snare: a single-center experience of more than 900 leads

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.
