Magnetic Resonance Imaging in People With Cardiac Implantable Electronic Devices: A Population Based Cohort Study.

ABSTRACT

Magnetic resonance imaging (MRI) is a widely used diagnostic tool with great benefits but has been considered contraindicated in people with cardiac implantable electronic devices (CIED). We investigated the occurrence of MRI in people with CIEDs and associated adverse events in a national cohort. Of 17,848 people included, 56 (0.3%) had at least one MRI; 16 of 16,102 (0.1%) with MRI non-compatible CIEDs and 40 of 1746 (2%) with MRI compatible CIEDs. Following MRI exposure, hospitalisations for potential serious adverse events were rare.
