What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study will test an AI software called Volta AF-Xplorer II during catheter ablation for atrial fibrillation. About 150 adults will be treated in real-world clinics, and researchers will track how well the AI helps guide the procedure. The goal is to see if the AI improves safety and reduces the return of irregular heart rhythms over two years.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Volta AF-Xplorer II AI software (used during cardiac mapping and catheter ablation)
What this could lead to
If successful, this could show that AI-assisted mapping improves outcomes for people with atrial fibrillation undergoing ablation, potentially reducing repeat procedures.
What could go wrong
This is an observational study without a control group, so results may not prove the AI is better than standard care. The software is already approved, so major breakthroughs are unlikely.

This is an AI summary of the original study and may miss details. Read our disclaimer.
