Perioperative Considerations for Modern Leadless Pacemakers.

Area of Science:

• Cardiology
• Medical Devices
• Anesthesiology

Background:

• Leadless pacemakers, approved in 2016, are increasingly used due to a better safety profile than traditional pacemakers.
• Advantages include lower infection rates and elimination of pocket hematoma and lead complications.
• Advancements now allow leadless synchronized atrioventricular pacing for atrioventricular block, broadening device indications.

Purpose of the Study:

• To provide an overview of leadless pacemaker technology.
• To review the evidence base and current indications for leadless pacemakers.
• To highlight unique perioperative considerations for anesthesiologists caring for patients with these devices.

Main Methods:

• Literature review of leadless pacemaker technology and clinical applications.
• Analysis of adverse event profiles compared to traditional pacemakers.
• Examination of recent technological advancements, including dual-leadless pacing.

Main Results:

• Leadless pacemakers demonstrate a reduced risk of infection, hematoma, and lead-related issues.
• Newer leadless systems enable synchronized atrioventricular pacing, expanding patient eligibility.
• Anesthesiologists require specific knowledge for perioperative management.

Conclusions:

• Leadless pacemakers represent a significant advancement in cardiac pacing technology.
• Their improved safety and expanded indications necessitate anesthesiologist awareness.
• Perioperative care planning is crucial for patients with leadless pacemakers.
