Conventional pacemaker lead extraction achieved an 86.7% success rate, with shorter lead dwell time significantly improving outcomes. Further trials are needed to compare these methods with newer laser techniques for cost-effectiveness.

Area of Science:

  • Cardiology
  • Medical Devices
  • Interventional Procedures

Background:

  • Laser sheath devices for lead extraction are emerging but not widely available and have cost implications.
  • Registry data on new devices should be compared with conventional methods due to a lack of randomized trials.
  • This study reports on pacemaker lead extraction using conventional methods at a single center.

Purpose of the Study:

  • To evaluate the success rate and outcomes of conventional pacemaker lead extraction techniques.
  • To identify factors associated with successful lead extraction.
  • To provide data for comparison with newer extraction methods.

Main Methods:

  • A total of 165 leads were extracted from 80 patients over 95 procedures.
  • Leads had a mean dwell time of 76 months; indications included infection, skin erosion, and device malfunction.

  • Conventional techniques like traction, stylets, dilator sheaths, Byrd workstation, and thoracotomy were employed.

    • Main Results:

    • Complete lead removal was achieved in 86.7% of cases (143 leads).
    • Shorter lead dwell time was significantly associated with higher extraction success rates (p<0.0001).
    • Major complications occurred in 3.2% of patients; significant bleeding in 12%.

    Conclusions:

    • Conventional pacemaker lead extraction demonstrates a high success rate of 86.7%.
    • Lead dwell time is a critical factor influencing extraction success.
    • Further randomized trials are recommended to compare conventional and laser extraction methods regarding clinical outcomes and cost-effectiveness.
