Study Description
Brief Summary:
This study will create a registry of patients with pacemakers and implantable ICDs who will undergo clinically indicated MRI and will document the incidence of any adverse events or changes in device parameters that might be associated with the procedure.

Condition or disease Intervention/treatment

Groups and Cohorts

Intervention Details:
    Device: MRI with pacemaker or ICD
    The aim of the present protocol is to prospectively determine the adverse event rate of non-thoracic MRI for patients with implanted cardiac devices by collecting pre- and post-MRI device interrogations in a multi-center registry.

Outcome Measures

Primary Outcome Measures :
  1. Rate of device failure. [ Time Frame: Anytime during follow up ]

Secondary Outcome Measures :
  1. Rate of device parameter changes [ Time Frame: Anytime during follow up ]

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Adult patient with pacemaker or ICD that is scheduled for a clinically indicated MRI.

Inclusion Criteria:

  • Male or female 18 years or older
  • Able to provide informed consent
  • Permanent implanted pacemaker or ICD
  • Strong clinical indication for MRI; in the clinical setting where MRI is the diagnostic modality of choice for a specific disease state without acceptable alternative imaging technology as determined by the ordering physician.
  • Patient is scheduled for non-thoracic MRI (joint, extremity, brain, pelvis, cervical, and lumbar or sacral spine)

Exclusion Criteria:

  • Metallic objects that represent a contraindication to MR imaging, including: intra-orbital or intra-ocular retained metal fragments, and intracranial vascular clips and coils
  • Claustrophobia unresponsive to pre-procedure sedatives
  • Morbid obesity (abdominal diameter >60 cm)
  • ICD or pacemaker generator placement prior to 2002
  • ICD and pacing dependent
  • Pregnancy
  • Device generator battery voltage at elective replacement index (ERI)
  • Presence of active implantable medical device (other than pacemaker or ICD)
  • 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 (approved by the FDA for exposure to MRI).
