What is being measured

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

  1. Ablaton scar

    The correlation between ablation lesion characteristics in the early phase after PVI and ablation scar at 3 months follow up.

    Measured: 3 months

Secondary outcomes (1)
  1. AF recurrence

    The relation between ablation lesion characteristics and AF recurrence at 1 year after the ablation procedure

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing MRI in people with Atrial Fibrillation, run by Amsterdam UMC, location VUmc.

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 4 inclusion and 10 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: status not confirmed, as of the sponsor's last update on 29 Jun 2022. 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?

Results are not available in the source record.

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?

Ablaton scar (time frame: 3 months). 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 29 Jun 2022; AzTrials last refreshed its copy on 1 Nov 2026.
