AB  - BACKGROUND: Magnetic resonance imaging (MRI) has been performed safely in 
      patients without MRI-conditional cardiac implantable electronic devices (CIEDs), 
      but experience specifically with cardiac magnetic resonance imaging (CMR) is 
      limited in this patient population. OBJECTIVE: Evaluate the safety of CMR in 
      non-MRI-conditional CIEDs and the interpretability of images using wideband 
      sequences. METHODS: We performed 114 consecutive CMR studies in 111 patients 
      (mean age 59 +/- 14 years, with 12 pacemakers, 73 implantable cardioverter 
      defibrillators, 29 biventricular defibrillators) using a wideband pulse sequence 
      for late gadolinium enhancement (LGE) imaging. A standardized protocol for device 
      management and patient monitoring was followed. Patients were evaluated for major 
      clinical adverse events and device parameter changes immediately after CMR and at 
      clinical follow-up. RESULTS: In total, 111 CMR studies were completed 
      successfully. There were no patient deaths, new arrhythmias, immediate generator 
      or lead failures, electrical resets, or pacing capture failures in dependent 
      patients. Right atrial, right ventricular, and left ventricular lead impedances 
      were significantly lower post CMR, with median differences -7 Omega (interquartile 
      range [IQR] -20 to 0 Omega; P < .0001), 0 Omega (IQR -19 to 0 Omega; P = .0001), and -10 Omega 
      (IQR -30 to 0 Omega; P = .023), respectively. These changes persisted through the 
      follow-up period, with median differences -18.5 Omega (IQR -41 to -66 Omega; P = .007), 
      -19 Omega (IQR -44 to -7 Omega; P = .006), and -30 Omega (IQR -130 to 0 Omega; P = .003), 
      respectively. Ninety-seven studies (87%) had no artifact limiting interpretation. 
      CONCLUSIONS: CMR can be performed safely in non-MRI-conditional CIEDs using a 
      standardized protocol. Use of a wideband pulse sequence for LGE imaging yields a 
      high rate of studies unaffected by artifact.
