The VR leadless pacemaker: Results of an expert panel using the RAND/UCLA method

Area of Science:

• Cardiology
• Medical Devices
• Clinical Guidelines

Background:

• Leadless pacemakers aim to minimize complications from traditional transvenous pacemaker implantation.
• Current international guidelines lack specific criteria for selecting patients for leadless pacemaker implantation.
• This study addresses the need for expert consensus on indications for VR leadless pacemakers.

Purpose of the Study:

• To develop a consensus document providing medical guidance for the indication and implantation of VR leadless pacemakers.
• To offer recommendations for health professionals involved in VR leadless pacemaker procedures.
• To standardize and optimize the implantation of Transcatheter Pacing System single-chamber devices.

Main Methods:

• A panel of interventional and non-interventional cardiologists utilized the RAND/UCLA appropriateness method.
• Experts rated 64 scenarios for atrial fibrillation and 192 for sinus rhythm patients.
• Scenarios were individually and group-rated to determine appropriateness for leadless pacemaker implantation.

Main Results:

• The consensus statement summarizes recommendations based on expert opinion and literature.
• Limitation for vascular access via the superior vena cava was a critical factor in patient selection.
• Appropriateness was classified as appropriate, inappropriate, or questionable based on median ratings and agreement.

Conclusions:

• Patient selection for VR leadless pacemaker implantation is influenced by life expectancy, infection risk, prosthetic valves, LVEF, vascular access, and mobility.
• Further prospective studies are required to refine and optimize current recommendations.
• The consensus aims to improve patient outcomes by standardizing leadless pacemaker implantation criteria.
