Safety evaluation of a leadless transcatheter pacemaker for magnetic resonance imaging use.

Background: Increased magnetic resonance imaging (MRI) adoption and demand are driving the need for device patients to have safe access to MRI.

Objective: The aim of this study was to address the interactions of MRI with the Micra transcatheter pacemaker system.

Methods: A strategy was developed to evaluate potential MRI risks including device heating, unintended cardiac stimulation, force, torque, vibration, and device malfunction.
