About this study

Official title: A Pilot Randomized Study of the Use of The Sentinel Device for Cerebral Protection During Atrial Fibrillation Ablation: MRI Imaging and Laboratory Sub-study

Researchers are determining whether the use of the Sentinel cerebral protection device during atrial fibrillation ablation will affect the occurrence of new cerebral infarcts in brain MRI. We are also studying if laboratory tests can be used to predict the rate of cerebral infarction and microbleeds in patients undergoing atrial fibrillation (AF) ablation procedures with and without use of the Sentinel Device.

Read the detailed description

Patients currently participating in the research study titled: "A Pilot Randomized Study of the Use of the Sentinel Device for Cerebral Protection during Atrial Fibrillation Ablation" will be asked to participate in this sub-study to collect additional MRI and laboratory data to support the main study. This study will assess the number, size and volume of new cerebral emboli in protected territories detected using MRI of the brain within 7 days after AF ablation in patients treated with the Sentinel device compared to controls not receiving the Sentinel device, and to assess if change in blood inflammatory markers is associated with silent cerebral lesions.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Magnetic Resonance Imaging (MRI)Device

    Cerebral MRI will be performed without gadolinium contrast using a 3 Tesla scanner prior to and 1 to 7 days after catheter ablation

  • Laboratory TestingOther

    Laboratory blood testing to include high sensitivity CRP (hs-CRP), interleukin-6 (IL-6), NT-proBNP and high sensitivity troponin prior to and post-ablation

What is being measured

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

  1. New cerebral infarcts

    Total number of new cerebral infarcts in the protected territories detected on brain MRI after ablation in the Sentinel device group vs control group

    Measured: day 1 to 7 after atrial fibrillation ablation

  2. Change in high sensitivity CRP (hs-CRP)

    High sensitivity CRP (hs-CRP) measured in mg/L to detect changes in peripheral markers of inflammation

    Measured: baseline 1 - 30 days prior to ablation, days 1 - 7 after atrial fibrillation ablation

  3. Change in interleukin-6 (IL-6)

    Interleukin-6 measured in pg/ml to detect changes in peripheral markers of inflammation

    Measured: baseline 1 - 30 days prior to ablation, days 1 - 7 after atrial fibrillation ablation

  4. Change in NT-proBNP

    NT-proBNP measured in pg/ml to detect changes in tissue damage

    Measured: baseline 1 - 30 days prior to ablation, days 1 - 7 after atrial fibrillation ablation

  5. Change in high sensitivity troponin

    High sensitivity troponin measure in ng/mL to detect changes in tissue damage

    Measured: baseline 1 - 30 days prior to ablation, days 1 - 7 after atrial fibrillation ablation

Questions about this trial

What is this clinical trial studying?

A study testing Magnetic Resonance Imaging (MRI) and Laboratory Testing in people with Atrial Fibrillation, run by Mayo Clinic at 1 site in United States.

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 4 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: withdrawn, as of the sponsor's last update on 14 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 was withdrawn before enrolling participants, so there are no results.

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?

New cerebral infarcts (time frame: day 1 to 7 after atrial fibrillation ablation). The study lists 5 primary outcomes in all. 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 14 Apr 2023.
