Transvenous Lead Extraction during Cardiac Implantable Device Upgrade: Results from the Multicenter Swiss Lead...

Area of Science:

• Cardiology
• Medical Device Technology
• Electrophysiology

Background:

• Patients with cardiac implantable electronic devices often require upgrades to more complex systems.
• Decisions regarding transvenous lead extraction (TLE), additional lead implantation, or lead abandonment are critical before upgrades.
• Limited evidence exists on the outcomes of TLE during device upgrade procedures.

Purpose of the Study:

• To analyze the outcomes of transvenous lead extraction (TLE) in patients undergoing cardiac device upgrades.
• To identify patient and procedural factors influencing TLE outcomes in this specific population.

Main Methods:

• A post hoc analysis of the multicenter Swiss TLE registry.
• Inclusion of 941 patients, with 83 undergoing TLE for device upgrade.
• Comparison of outcomes between upgraded patients and those with TLE for other reasons.

Main Results:

• Rotational mechanical sheaths were more frequently used in upgraded patients (59% vs. 42.7%).
• Upgraded patients had longer procedure times (160 min vs. 105 min).
• Clinical success rates were similar (97.6% vs. 93.0%), with no increased risk of complications (7.2% vs. 5.5%).

Conclusions:

• Transvenous lead extraction (TLE) is an effective procedure during cardiac device upgrades.
• TLE at the time of device upgrade does not introduce a disproportionate risk of complications.
