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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at how two different catheters used to treat atrial fibrillation (a type of irregular heartbeat) affect the temperature of the esophagus (the tube connecting the mouth to the stomach) and the risk of injury to it. About 30 adults with paroxysmal atrial fibrillation will be enrolled. The goal is to understand which approach is safer for the esophagus during the procedure.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 30 people

The number the study aims to enrol. It can still change while the study runs.

Started

Oct 2024

Expected to finish

Mar 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

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

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Provision of signed and dated informed consent form 2. Stated willingness to comply with all study procedures and availability for the duration of the study 3. Male or female, aged greater than or equal to 18 years 4. Diagnosed with paroxysmal atrial fibrillation 5. Undergoing RF catheter ablation for treatment of paroxysmal atrial fibrillation that will involve circumferential point-by-point radiofrequency ablation pulmonary vein isolation with no additional left atrial posterior wall ablation planned Exclusion Criteria: 1. Patients who have undergone prior left atrial ablation procedures. 2. Patients where the use of the Q-DOT Micro ablation catheter in QMODE+ (i.e. temperature-controlled very-high-power short-duration ablation) is felt to be unsafe. 3. Patients who have contraindications to capsule endoscopy, or GI conditions that may increase the risks of capsule endoscopy (e.g. esophageal strictures, inflammatory bowel disease, etc) 4. Any records flagged "break the glass" or "research opt out."
