A single-center registry to prospectively evaluate the safety of non-cardiac/non-thoracic magnetic resonance imaging (MRI) in patients with implanted cardiac devices (pacemakers and implantable cardioverter defibrillators).

• Morbid obesity which results in body contact with the magnet façade
• Pacemaker or ICD generator implanted prior to 2002
• ICD patients who are pacing dependent
• Pregnancy
• Device generator at ERI (elective replacement interval)
• Presence of other active implanted medical device
• Presence of abandoned leads (with the exception of post CABG temporary epicardial pacing wires)
• Presence of implanted cardiac device in the abdominal position
• Pacemaker or ICD that is labeled as MRI-Conditional by the FDA
• Pacemaker or ICD implanted less than 6 weeks prior to MRI scan
