Managing patients with advisory defibrillator leads: what can we learn from published data?

Area of Science:

• Cardiology
• Biomedical Engineering
• Medical Device Safety

Background:

• Defibrillator lead advisories generate significant patient and physician concern, impacting management decisions.
• Previous advisories, such as for Medtronic Sprint Fidelis and St. Jude Riata leads, highlight potential complications.
• A need exists for an evidence-based approach to managing these lead advisories.

Purpose of the Study:

• To review the literature and provide an evidence-based approach to defibrillator lead management following advisories.
• To evaluate the risks and benefits of lead replacement versus abandonment.
• To inform clinical decision-making regarding compromised implantable cardioverter-defibrillator (ICD) leads.

Main Methods:

• Literature review focusing on complications associated with specific advisory leads (Medtronic Sprint Fidelis, St. Jude Riata).
• Analysis of consequences related to interventions, including lead replacement and extraction.
• Assessment of the risks associated with lead extraction versus abandonment.

Main Results:

• A restrained approach to premature replacement of advisory leads is recommended.
• Replacing leads during scheduled generator replacement may be opportune if electrical failure rates are elevated.
• No evidence supports the extraction of non-functional advisory leads; extraction risks often outweigh abandonment.

Conclusions:

• Clinical management of defibrillator leads with advisories should prioritize a conservative strategy.
• Scheduled generator replacement offers a potential window for proactive lead management in select cases.
• Abandoning non-functional leads is generally safer than attempting extraction due to procedural risks.
