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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests whether a magnetic sensor placed on the skin can accurately measure blood pressure in the jugular vein and radial artery, compared to standard invasive methods using catheters. The study involves 10 adults with complex congenital heart disease or chronic right heart failure who are already scheduled for a right heart catheterization. If the sensor proves reliable, it could offer a non-invasive way to monitor right heart function over time.

What this could mean

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

Active substance
Magnetic sensor
What this could lead to
If successful, this could provide a simpler, non-invasive way to monitor right heart function in patients with complex congenital heart disease or chronic right heart failure.
What could go wrong
This is a very small early-stage study (10 participants) focused on validating a device, not treating disease. The sensor may not match the accuracy of invasive measurements.
