Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Freedom From MRI-scan Related Complications* Related to St. Jude Medical™ MR Conditional ICD System

    \*A complication is a serious adverse device effect (SADE) that requires an invasive intervention or leads to death. The primary endpoint analysis will be performed for each study phase separately.

    from MRI scan visit to 1 month post-MRI scan visit

Other Outcomes (6)

  • The Average Specific Absorption Rate (SAR)

    MRI scan visit

  • Number of Participants With Freedom From MRI-scan Related Complications* Related to St. Jude Medical™ MR Conditional ICD System

    from MRI scan visit to 1-month post MRI scan visit

  • Proportion of SJM High Voltage Lead Implanted With SJM MR Conditional ICD With Sensing Amplitude Decrease of ≤ 50% From Pre-MRI Scan Testing to 1 Month Post-MRI Scan Testing

    from pre MRI scan to 1-month post MRI scan

  • +3 more other outcomes

Study Arms (2)

Thoracic MRI Scan with 1.5 Tesla MRI

EXPERIMENTAL

Subjects will be enrolled at least 60 days post successful St. Jude Medical™ MR Conditional ICD System implant. Enrolled subjects will undergo an elective 1.5T MRI scan within 30 days post enrollment. Post MRI visit all subjects will be followed up at 1-Month post MRI visit.

Radiation: Thoracic MRI Scan

Thoracic MRI Scan with 3 Tesla MRI

EXPERIMENTAL

Subjects will be enrolled at least 60 days post successful St. Jude Medical™ MR Conditional ICD System implant. Enrolled subjects will undergo an elective 3T MRI scan within 30 days post enrollment. Post MRI visit all subjects will be followed up at 1-Month post MRI visit.

Radiation: Thoracic MRI Scan

Interventions

The ICD system will be exposed to MRI scan of thoracic region, where the radiofrequency (RF) component of the scan is maximized.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject is pectorally implanted with St. Jude Medical™ MR Conditional ICD System for at least 60 days
  • Subject is willing to undergo an elective MRI scan without sedation NOTE: Antianxiety agents (e.g. minor tranquilizers, etc.) may be used as long as the patient can communicate with site personnel during the MRI scan
  • Subject's ventricular bipolar capture threshold is stable \< 2.5V @ 0.5ms
  • Subject's ventricular sensing is measurable (patient has underlying rhythm \> 30bpm) and the sensing amplitude is stable \> 4mV
  • Subject is able to provide informed consent for study participation (legal guardian or legally authorized representative is NOT acceptable)
  • Subject is willing and able to comply with the prescribed follow-up tests and procedures
  • Subject is not contraindicated for an MRI scan (per the MRI Screening Form)

You may not qualify if:

  • Subject is pacemaker dependent
  • Subject has a non SJM MRI compatible endocardial lead implanted or capped
  • Subject has another existing active implanted medical device, e.g., neurostimulator, infusion pump, etc. that has MR labeling that will not allow the MRI scans per this protocol to be completed.
  • Subject has a high voltage lead revision incidence \< 60 days of the enrollment visit
  • Subject has other non-MRI compatible device or material implanted NOTE: MRI compatible knee replacements, hip replacements, stents, etc. may be included as long as the labeling of these devices allow MRI scans conducted per this protocol NOTE: MRI compatible mechanical, prosthetic, and bioprosthetic heart valves may be included as long as the labeling of these devices allow for MRI scans conducted per this protocol NOTE: Non-removable dental implants may be included
  • Subject has a lead extender, adaptor, or capped/abandoned lead
  • Subject is enrolled or intend to participate in a clinical drug and/or device study (investigational device, investigational drug, new indication for a device or drug or additional testing beyond standard of care procedures), which could confound the results of this trial as determined by SJM.
  • Subject is pregnant or planning to become pregnant during the duration of the subject's participation in the study
  • Subject has a life expectancy of less than 12 months due to any condition
