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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two types of heart ablation for people with persistent atrial fibrillation: pulsed field ablation and radiofrequency ablation. The goal is to see which one causes fewer stomach problems after the procedure. Twenty participants will be matched by age and health factors, and their stomach emptying will be measured before and after treatment.

What this could mean

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

Active substance
Pulsed Field Ablation and Radiofrequency Ablation
What this could lead to
If this study shows that pulsed field ablation causes fewer stomach issues, it could point toward a gentler procedure for treating atrial fibrillation.
What could go wrong
This is a very small, early-stage study with only 20 people, so results may not apply to everyone. It is not designed to prove long-term safety or effectiveness.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Patients with persistent atrial fibrillation aged 18-80 years, scheduled for first-time catheter ablation (pulsed field or radiofrequency) with pulmonary vein isolation plus left atrial posterior wall isolation at a single center. The study aims to compare postoperative gastric motility between the two ablation modalities.
