About this study

Official title: Medtronic Magnetic Resonance (MR) Conditional Tachyarrhythmia Therapy Products Post-approval Study

Following product approval, further confirmation of the MR Conditional Tachyarrhythmia Therapy Systems sensing and detection performance post MRI exposure will be obtained by actively monitoring de-identified device data obtained through the Medtronic CareLink® Network.

Read the detailed description

Pre-clinical testing and clinical data has demonstrated the safety and effectiveness of magnetic resonance (MR) Conditional Tachyarrhythmia Therapy Systems in the MR environment when used according to labeling requirements. Following approval, further confirmation of the MR Conditional Tachyarrhythmia Therapy Systems sensing and detection performance post MRI exposure will be obtained by actively monitoring de-identified device data obtained through the Medtronic CareLink® Network. MR conditional tachyarrhythmia therapy system enrolled in the Medtronic CareLink® Network (CL) will be used to prospectively assess spontaneous Ventricular Fibrillation (VF) episode detection following MRI exposure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The proportion of episodes with ≥ 5 seconds VF detection delay in the MR conditional tachyarrhythmia therapy system following MRI exposure.

    The primary objective will be analyzed and reported when 50 patients with a true VF episode following MR exposure have been identified

    Measured: up to 5 years post-approval.

Secondary outcomes (2)
  1. The number of patients with 2 or more scans

    The estimate of patients receiving multiple MRI scans will include all patients regardless if the patient has experienced a VF episode.

    Measured: up to 5 years post-approval

  2. Pre-MRI and post-MRI LV lead PCT measurements obtained through CareLink

    Pre-MRI and post-MRI LV lead PCT measurements obtained through CareLink will be summarized for MR CRT-D patients. Summary statistics will be presented separately for pre-MRI and post-MRI PCT measurements

    Measured: up to 5 years post-approval

Questions about this trial

What is this clinical trial studying?

An observational study of Tachyarrhythmia, run by Medtronic.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The proportion of episodes with ≥ 5 seconds VF detection delay in the MR conditional tachyarrhythmia therapy system following MRI exposure. (time frame: up to 5 years post-approval.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jun 2019.
