Stepwise Approach for Transvenous Lead Extraction in a Large Single Centre Cohort

Area of Science:

• Cardiovascular Medicine
• Electrophysiology
• Medical Device Extraction

Background:

• Transvenous lead extraction is increasingly common due to infection, lead dysfunction, and device upgrades.
• Single-method approaches may compromise success rates and increase complication risks.
• A systematic, stepwise strategy without laser sheaths is explored.

Purpose of the Study:

• To evaluate the efficacy and safety of a stepwise approach for transvenous lead extraction.
• To assess success rates across different levels of invasiveness in lead extraction.
• To analyze factors influencing extraction success, including lead dwell time.

Main Methods:

• A consecutive series of transvenous lead extraction procedures over seven years were analyzed.
• A stepwise approach was employed: careful traction, lead locking stylets (LLD), mechanical non-powered dilator sheaths, mechanical powered sheaths, and femoral snares.
• Procedures were categorized by the invasiveness of the method used.

Main Results:

• The overall success rate for transvenous lead extraction was 93.1%, with a clinical success rate of 94.1%.
• Success rates increased with invasiveness: simple traction (31.5%), LLD (42.7%), non-powered sheaths (84.1%), and powered sheaths (92.6%).
• Major complications were rare (0.4%), including one death (0.2%), with minor complications in 6.5% of patients.

Conclusions:

• A stepwise approach, progressing from less to more invasive techniques, is effective and safe for transvenous lead extraction.
• This strategy achieves high success rates and low complication rates without relying on laser sheaths.
• Shorter lead dwelling times correlated with higher success rates in less invasive steps and overall extraction.
