When pacing or defibrillator leads become redundant: Extract or abandon?

Area of Science:

• Cardiology
• Electrophysiology
• Medical Device Management

Background:

• The 2017 Heart Rhythm Society consensus did not favor extracting or abandoning redundant pacing or defibrillator leads.
• No trials demonstrate improved patient outcomes with redundant lead extraction.
• Experienced centers often recommend removal to prevent future complications.

Purpose of the Study:

• To evaluate the risks and benefits of extracting versus abandoning redundant cardiac leads.
• To inform clinical decision-making regarding the management of non-functional or superfluous leads.

Main Methods:

• Literature review and analysis of existing data on redundant lead management.
• Comparison of patient outcomes and procedural risks between lead extraction and abandonment.
• Assessment of cost-effectiveness and resource utilization for both strategies.

Main Results:

• Over 90% of abandoned leads have uneventful follow-up, suggesting extraction is not always necessary.
• Immediate extraction carries a small but significant risk, potentially leading to more adverse events population-wide compared to selective extraction.
• Lead abandonment is a cost-effective and widely accessible procedure, unlike extraction which requires specialized centers and equipment.

Conclusions:

• Abandoning redundant leads is a safe and cost-effective strategy for many patients.
• Immediate extraction of all redundant leads may lead to a higher overall incidence of adverse events.
• Extraction should be reserved for cases with specific future lead complications, despite potentially higher risks at that later time.
