About this study

Official title: External Validation of the Left Atrial Sphericity as Predictor of Recurrence After Atrial Fibrillation Ablation: A Multicenter Observational Study.

This is a Multicenter Observational 1-year retrospective cohort study evaluating the predictive value of the Left Atrial Sphericity on the recurrence rate of atrial fibrillation after pulmonary vein ablation procedure.

Inclusion of consecutive patients undergoing AF ablation during 2013 in whom a 3D-imaging of the left atrium (Cardiac CT or MRA) was acquired prior to the procedure and when procedural/follow-up data was prospectively collected.

Read the detailed description

Validation of the predictive value of the Left Atrial Sphericity for AF recurrence of atrial fibrillation after a pulmonary vein ablation procedure in an external, multicenter cohort.

In total, 9 centers will include consecutive patients who underwent AF ablation from january to december 2013 in whom a 3D-imaging of the left atrium (Cardiac CT or MRA) was acquired prior to the procedure and when procedural/follow-up data was prospectively collected.

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillation and Recurrence, run by Hospital Clinic of Barcelona at 9 sites in Spain.

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 5 inclusion and 1 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 11 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in Spain. 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 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?

Atrial Fibrillation Recurrence (>30 seconds) (time frame: One Year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02373982, which also lists 4 linked publications.

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 11 Apr 2017.
