Lead extractions: the Zwolle experience with the Evolution mechanical sheath

Area of Science:

• Cardiovascular Medicine
• Medical Devices
• Electrophysiology

Background:

• Chronic lead extraction is crucial for managing cardiac electronic device complications.
• The Evolution sheath is a powered device designed for challenging lead removal.

Purpose of the Study:

• To evaluate the safety and efficacy of the Evolution sheath for chronic lead extraction.
• To compare the performance of unidirectional and bidirectional Evolution sheath types.

Main Methods:

• A prospective study examined 111 lead extractions in 77 patients from 2009 to 2014.
• Leads were extracted using either the original unidirectional or the newer bidirectional R/L type Evolution sheath.
• Success was defined by complete lead material removal (procedural success) or partial removal with no complications (clinical success).

Main Results:

• The Evolution sheath achieved an 88% complete procedural success rate and a 98% clinical success rate.
• The bidirectional R/L type sheath showed significantly higher procedural success (96%) compared to the unidirectional type (80%).
• No major complications occurred; minor complications were observed in 8% of cases.

Conclusions:

• The Evolution sheath is a safe and effective option for chronic lead extraction.
• The bidirectional R/L type Evolution sheath offers improved procedural success rates.
