What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested a special breathing technique during atrial fibrillation ablation to see if it reduces catheter movement. Fifty-two adults with atrial fibrillation were given both standard and high-frequency, low-volume ventilation during their procedure. The goal was to see if the new method keeps the catheter more stable, which could make the ablation more precise and safer.

What this could mean

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

What this could lead to
If successful, this breathing technique could make heart ablation procedures more stable and potentially safer, improving outcomes for atrial fibrillation patients.
What could go wrong
This is a small pilot study with only 52 participants. The findings are preliminary and need confirmation in larger trials. The special breathing method may not work for all patients or could cause side effects.
