This study examines whether MRI is safe in patients with cardiac implantable electronic device (CIED) excluded from published protocols, e.g. patients with abandoned leads or pacemaker dependency. A total of 162 MRI scans were obtained in 142 consecutive patients with CIED’s. Cardiac scans were performed in 94 patients and spinal/brain scans were performed in 47 patients. Only one patient developed ventricular tachycardia during a spine scan and was removed from the scanner for device reactivation without consequences. No other adverse events were noted. The devices interrogated parameters essentially remained the same immediately, 1-week after, and 3-months after the scans.
