Ancillary tools in pacemaker and defibrillator lead extraction using a novel lead removal system

Area of Science:

• Cardiology
• Medical Devices
• Interventional Procedures

Background:

• Pacemaker and implantable cardioverter-defibrillator (ICD) lead extraction is crucial for managing complications like infection or malfunction.
• The VasoExtor system offers a preliminary successful approach for percutaneous lead removal.
• Experience indicates the need for additional tools to optimize extraction success rates.

Purpose of the Study:

• To evaluate the efficacy of the VasoExtor system with various locking stylets (S, K, Magic) for pacemaker and ICD lead extraction.
• To determine the necessity and types of ancillary tools required to enhance lead extraction success.
• To assess the overall success and complication rates associated with percutaneous lead extraction.

Main Methods:

• A retrospective analysis of 34 patients undergoing extraction of 51 leads (48 pacemaker, 3 ICD) over 3 years.
• Utilized standard (S, K) and newer (Magic) locking stylets with the VasoExtor system.
• Documented the use of ancillary tools, including noose catheters, pigtail catheters, bioptomes, and Amplatz catheters, when standard methods were insufficient.

Main Results:

• Lead extraction was successful in 97% of patients (33/34) and 98% of leads (50/51) without major complications.
• Ancillary tools were required in 26.5% (9/34) of patients to facilitate extraction.
• Specific challenges included inability to lock leads and retrieval of lead fragments, necessitating combined or alternative approaches.

Conclusions:

• Percutaneous lead extraction using the VasoExtor system with locking stylets is highly effective.
• A significant proportion of cases require ancillary tools to achieve complete lead removal.
• The integration of various tools enhances the success rate of complex pacemaker and ICD lead extractions.
