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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 explores whether a cardiac MRI can safely and effectively gather the same heart pressure and flow measurements normally obtained through right heart catheterization, a more invasive procedure. Researchers will attempt to perform the catheterization inside the MRI machine using a special probe visible on the scan. If it works, patients with conditions like pulmonary hypertension or cardiomyopathy could avoid a separate invasive procedure.

What this could mean

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

Active substance
Cardiac MRI with Swan Ganz probe navigation using gadolinium
What this could lead to
If successful, this approach could replace invasive right heart catheterization with a safer, MRI-based procedure for diagnosing certain heart conditions.
What could go wrong
This is a small feasibility study with only 35 participants, so results may not apply broadly. The procedure still requires a catheter and contrast agent, carrying some risk.

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

Inclusion Criteria: * Patient over 18 years old * Having an indication for a diagnostic of right cardiac catheterization at the J Cartier Hospital for one of the following pathologies: dilated, restrictive cardiomyopathy, pulmonary arterial hypertension, chronic constrictive pericarditis, chronic post-embolic pulmonary heart. * Subject affiliated or beneficiary of a social security scheme * Patient having freely signed the informed consent. Exclusion Criteria: * Pregnancy (declarative, known pregnancy, any unexplained period delay in a woman of childbearing age) * Presence of a contraindication to MRI: intraocular metallic splinter, surgical clip for cerebral aneurysm, claustrophobia, defibrillator, implanted electronic equipment) or to gadolinium chelates (anaphylactic reactions to gadolinium chelates, creatinine clearance \<= 30 ml / min). * Protected patients: Adults under guardianship, curatorship or other legal protection, deprived of their liberty by judicial or administrative decision; Pregnant, breastfeeding or parturient woman; Hospitalized without consent. * Patient participating in another clinical study
