Safety and utility of magnetic resonance imaging in patients with cardiac implantable electronic devices.

Background: Off-label magnetic resonance imaging (MRI) for patients with cardiac implantable electrical devices has been limited owing to concerns about safety and unclear diagnostic and prognostic utility.

Objective: The purpose of this study was to define major and minor adverse events with off-label MRI scans.

Methods: We prospectively evaluated patients with non-MRI-conditional cardiac implantable electrical devices referred for MRI scans under a strict clinical protocol.
