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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a new paired-ring sizing tool used during mitral valve repair surgery. The tool measures the length of leaflet coaptation, which is how well the valve leaflets seal. Researchers want to see if this method gives accurate measurements compared to standard echocardiography. The study includes adults scheduled for mitral repair, and the tool is used only for observation, not to guide surgical decisions.

What this could mean

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

Active substance
A novel paired-ring sizing tool used once during mitral valve repair surgery, purely to measure leaflet coaptation length without influencing surgical decisions.
What this could lead to
If the sizing method proves accurate, it could help surgeons choose better ring sizes during mitral repair, potentially improving long-term valve function.
What could go wrong
This is a small, early study with 22 participants, so results may not apply broadly. The device is observational only, so it cannot directly improve outcomes, and measuring errors or imaging variability could limit conclusions.
