Safety of Magnetic Resonance Imaging in Non-MRI Conditional Pacemakers and ICD Devices

Safety of Magnetic Resonance Imaging in Non-MRI Conditional Pacemakers and ICD Devices

The primary objective of the study is to determine the safety of MRI in patients with non-MRI conditional pacemakers. The secondary objective is to determine if there are clinically relevant parameter changes in the devices.

Inclusion Criteria. All patients with non-MRI conditional pacemakers and ICDs between the ages of 18-85 will be eligible to participate. Medical records will be reviewed to confirm the date and make/model of device implanted. Ordering physician discusses the MRI request with radiologist, documenting that there is no appropriate alternate imaging test. Patient must have an appointment with a cardiologist/electrophysiologist prior to MRI. Banner Health policy for standard of care guidelines involving patients receiving MRI's will be followed.

Exclusion Criteria. Patients will be excluded from MRI based on the Department of Radiology protocol. Additional exclusion criteria include: ICD and pacemaker dependent, Pacemaker inserted before 2002, Epicardial leads, fractured leads, abandoned leads, or temporary pacemakers (post-coronary artery bypass graft temporary epicardial pacing wires are acceptable), Patient not awake or unable communicate, Battery voltage at elective replacement interval, implanted non-MRI conditional device (other than pacemaker/ICD).
