Initial experience of pacemaker and implantable cardioverter defibrillator lead extraction with the new GlideLight 80 Hz laser sheaths

OBJECTIVES: Laser lead extraction is a challenging procedure, especially in patients with old or multiple pacemaker (PM) or implantable cardioverter defibrillator (ICD) leads. The mechanical force is a leading cause of complications during the extraction procedure. Use of new laser sheaths, which deliver a rate of 80 pulses per second, may probably reduce intraoperative adverse events by reduction of extraction force. METHODS: Between January 2012 and April 2013, 76 PM and ICD leads were treated in 38 patients using GlideLight 80 Hz laser sheaths. Indications for lead removals were pocket infection (42.1%), septicaemia or endocarditis (23.7%), lead dysfunction (31.6%) and upgrade from PM to ICD (2.6%). Data on procedural success rates, intra-and postoperative outcomes, as well as 30-day mortality were collected into a database and analysed retrospectively. RESULTS: The mean patient age was 62.0 +/- 17.7 years (range 18-83), and 73.7% were male. The mean time from initial lead implantation was 96.0 +/- 58.3 months (range 24-288). Thirty-seven (48.7%) PM and 39 (51.3%) ICD leads had to be extracted. The mean procedural time was 68.3 +/- 27.3 min (range 35-115). Seventy-two of 76 leads (94.8%) were completely removed, partial removal was achieved in 2 (2.6%) leads and a failure of extraction occurred in 2 (2.6%) leads. The overall complication rate was 5.2%, including one major (superior vena cava perforation) (2.6%) and one minor (pocket haematoma) (2.6%) complication. No death occurred during the 30-day follow-up. CONCLUSIONS: The GlideLight 80 Hz laser sheath allows safe and effective removal of chronically implanted PM and ICD leads, combining high procedural success with low complication rates.
