Nontransvenous Cardiovascular Implantable Electronic Device Technology-A Review for the Anesthesiologist

Area of Science:

• Cardiology
• Anesthesiology
• Biomedical Engineering

Background:

• Transvenous cardiac implantable electronic devices (CIEDs) are associated with complications.
• A shift towards leadless pacemakers and subcutaneous implantable cardioverter-defibrillators (S-ICDs) is occurring globally.
• Novel CIEDs have unique design and functionality distinct from traditional transvenous systems.

Purpose of the Study:

• To review the features and capabilities of leadless pacemakers and S-ICDs.
• To provide guidance on perioperative management for these nontransvenous CIEDs.
• To address the gap in current perioperative guidelines regarding novel CIEDs.

Main Methods:

• Literature review of leadless pacemakers (e.g., Micra) and S-ICDs.
• Analysis of device features, functionality, and potential perioperative implications.
• Synthesis of existing knowledge to formulate management recommendations.

Main Results:

• Leadless pacemakers and S-ICDs represent significant advancements in cardiac pacing and defibrillation.
• These devices differ from transvenous systems in implantation, sensing, and pacing mechanisms.
• Current perioperative guidelines lack specific recommendations for managing patients with these novel devices.

Conclusions:

• Anesthesia providers must understand the unique characteristics of leadless pacemakers and S-ICDs.
• Developing specific perioperative management strategies is crucial for patient safety.
• Further research and guideline development are needed for optimal care of patients with nontransvenous CIEDs.
