Magnetic resonance imaging at 1.5 T in 7 patients with implantable cardioverter defibrillators resulted in no permanent device impairment when appropriate reprogramming and monitoring were used.
Observational (n=7)
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.
Gimbel et al. (Fri,) conducted a observational in Implantable Cardioverter Defibrillators (ICDs) (n=7). Magnetic Resonance Imaging (MRI) with screening, reprogramming, and monitoring was evaluated on Change in pacing, sensing, impedances, charge times, or battery status post-MRI. Magnetic resonance imaging at 1.5 T in 7 patients with implantable cardioverter defibrillators resulted in no permanent device impairment when appropriate reprogramming and monitoring were used.
