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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares a new guidewire (AccuSafe) to the standard needle used to cross the heart wall during catheter ablation for atrial fibrillation. The goal is to see if the guidewire is safer and more effective, especially when done without X-ray guidance. 80 patients will be randomly assigned to one of the two devices, and researchers will track success rates, procedure time, and complications.

What this could mean

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

Active substance
AccuSafe transseptal guidewire
What this could lead to
If successful, this guidewire could make a key step in AF ablation safer, faster, and radiation-free for patients and doctors.
What could go wrong
This is a small, early-stage study (80 patients) comparing a device to standard care. Results may not apply to all patients or settings.

Study facts

What this study's own registry entry says, in plain language.

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 80 people

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

Started

Feb 2025

Expected to finish

Feb 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.

Ages

18 to 75 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

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 Age 18-75 years (inclusive); ② Clinically diagnosed with atrial fibrillation, indicated for radiofrequency ablation, and scheduled for catheter ablation; ③ Voluntarily agrees to participate in the trial and has signed informed consent; ⑤ Willing to comply with the trial requirements and complete the required follow-up. (All patients must have normal fossa ovalis anatomy confirmed by preoperative echocardiography; complex cases such as patent foramen ovale and atrial septal aneurysm are excluded) Exclusion Criteria: ① History of patent foramen ovale, atrial septal defect, post-atrial septal defect closure, post-valve replacement, or post-permanent pacemaker implantation; ② Intraoperative anatomical abnormalities requiring conversion to X-ray guidance-these patients will be withdrawn from the study and treated as dropouts.
