Abstract

Objective: To determine if simple strategies used to safely scan pacemaker patients could be applied to implantable cardioverter defibrillator (ICD), patients undergoing MRI allowing ICD patients to undergo MRI as well.

Interventions: Screening, reprogramming, and monitoring strategies were used to facilitate MRI.

Results: Seven patients underwent eight MRI scans at 1.5 T. Post-MRI, all devices demonstrated no change in pacing, sensing, impedances, charge times, or battery status. The patient undergoing a lumbar spine scan experienced a "power-on-reset" of his ICD without permanent impairment of his device.

Conclusion: Scanning of ICD patients might be performed if appropriate reprogramming and monitoring is implemented.
