Summary
The German Laser Lead Extraction Registry (GALLERY) found laser lead extraction procedures to be highly successful and safe. Key predictors for complications included female sex and abandoned leads, while infection and age predicted mortality.
Area of Science:
- Cardiology
- Medical Device Technology
- Public Health
Background:
- Implantable cardioverter-defibrillators (ICDs) and pacemakers require lead extraction for various reasons.
- Laser lead extraction is a specialized technique for removing these leads.
- Data on the safety and efficacy of laser lead extraction in a large, real-world setting are crucial.
Purpose of the Study:
- To investigate the safety and efficacy of laser lead extraction procedures.
- To identify predictors for procedural complications and mortality.
- To assess outcomes in a national multicentre registry.
Main Methods:
- Retrospective analysis of the German Laser Lead Extraction Registry (GALLERY).
- Inclusion of 2524 patients undergoing laser lead extraction between January 2013 and March 2017.
- Data collection on procedural success, complications, and mortality.
Main Results:
- High clinical procedural success rate (97.86%) and complete lead removal (94.85%).
- Low overall complication rate (4.32%), with procedure-related mortality at 0.55%.
- Lead age ≥10 years predicted procedural failure; female sex and abandoned leads predicted complications.
Conclusions:
- Laser lead extraction demonstrates high efficacy and a favorable safety profile.
- Identifying patient-specific risk factors is essential for optimizing outcomes.
- Systemic infection, advanced age, and chronic kidney disease are significant predictors of mortality.
