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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 a new imaging system called CHORUS IDx in 200 people scheduled for a heart ablation procedure. The system takes pictures inside the heart to help doctors see better during the procedure. The main goal is to check if the device is safe and to collect images that will be used to improve the software.

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 could help improve imaging software for guiding heart procedures, potentially making them safer and more effective.
What could go wrong
This is a very early, first-in-human study focused on data collection, not treatment. The device may not work as expected, and there is a risk of procedure-related side effects.

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

An estimate. End dates often move.

Lead sponsor

A company

The lead sponsor is a pharmaceutical, biotech, or medical-device company.

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

Inclusion Criteria: 1. Subjects who are able and willing to provide written informed consent prior to any study procedure. 2. Subjects who are planned for an ablation procedure for any atrial arrhythmia using any commercially available Boston Scientific Ablation System, per physician's judgement and hospitals' standard practice. 3. Subjects who are willing and able to participate in all testing and assessments associated with this clinical study at an approved clinical investigation center. 4. Subjects whose age is 18 years or above, or who are of legal age to give informed consent specific to state and national law. Exclusion Criteria: 1. Any of the following cardiac implanted devices * Any prosthetic mitral or tricuspid heart valve, such as ring, repairs or clips * Atrial septal defect (ASD) occluders including interatrial baffle, closure device, patch, or patent foramen ovale or ASD occluder 2. Subjects with contraindications related to the use of the CHORUS IDx™ System: * Subjects with inadequate vascular access * Subjects with active systemic infection * Subjects with presence of a known intracardiac thrombus in the chamber of use 3. Women who are confirmed to be pregnant or lactating at the time of the Index Procedure 4. Presence of other medical conditions, that, in the investigator's opinion, could limit the subject's ability to participate in the study 5. Subjects who are currently enrolled in another investigational study or registry that would directly interfere with the current study, except when the subject is participating in a mandatory governmental registry, or a purely observational registry with no associated treatments; each instance must be brought to the attention of the Sponsor to determine eligibility
