NCT ID NCT03292497

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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 whether using a specific set of measurements (an algorithm) to decide between repairing or replacing a leaky mitral valve leads to better outcomes than letting the surgeon choose. About 110 patients with severe ischemic mitral regurgitation will be randomly assigned to either the algorithm-guided approach or standard surgeon preference. Researchers will compare changes in heart size and function over 12 months after surgery.

What this could mean

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

Active substance
Treatment algorithm for mitral valve surgery
What this could lead to
If successful, this could provide a clear, evidence-based way to choose between valve repair or replacement, potentially improving heart function and reducing complications.
What could go wrong
This is a relatively small, early-stage study (110 patients) comparing two surgical approaches. The algorithm may not prove superior to surgeon preference, and results may not apply to all patients.

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 110 people

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

Started

Jan 2018

Expected to finish

Nov 2028

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 years and older

Sex

Anyone

Healthy volunteers

Not accepted

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