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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 pilot study at Mayo Clinic will use cardiac MRI scans to examine how the heart's main pumping chamber changes in people with severe mitral regurgitation before and after valve repair surgery. The goal is to see if this approach can help identify patients at risk of developing heart weakness after surgery. Thirty adults undergoing robotic mitral annuloplasty will receive two MRI scans—one before surgery and another 6–12 months later.

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 study could pave the way for a larger trial that helps doctors better predict which patients with mitral regurgitation are at risk of heart dysfunction after surgery.
What could go wrong
This is a very small pilot study with only 30 participants, designed mainly to test feasibility. It is not testing a treatment, so it cannot directly improve patient outcomes.

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

Inclusion Criteria: * Age \>= 18 * Male or Female * A diagnosis of severe chronic primary mitral regurgitation * Undergoing isolated robotic mitral annuloplasty at Mayo Clinic Rochester * Patients must have the ability to consent or have an appropriate representative available to do so. Exclusion Criteria: * Prior valve intervention, * Concomitant valve surgery at the time of mitral annuloplasty (e.g. tricuspid annuloplasty, aortic valve replacement). * Concomitant \>= moderate regurgitation or stenosis in any other valve by preoperative echocardiography * History of prior myocardial infarction * History of cardiomyopathy unrelated to mitral regurgitation (e.g. dilated, hypertrophic, infiltrative) * Pregnancy. Women of childbearing potential will be verbally screened by clinical staff during as part of routine pre-MRI evaluation. If a subject is unsure whether they could be pregnant, a negative pregnancy test will be performed prior to scanning. * Implantable devices that would be a contraindication to MRI * Severe allergy to gadolinium MRI contrast
