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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 whether doctors can use ultrasound (instead of X-rays) to guide a thin tube called a Swan-Ganz catheter into the right heart artery in people with pulmonary hypertension. The goal is to see if this method is safe, fast, and accurate. About 35 adults will take part. If it works, it could reduce radiation exposure and make the procedure easier to do at the bedside.

What this could mean

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

Active substance
ultrasound-guided pulmonary artery catheterization
What this could lead to
If successful, this could make catheter placement safer and more accessible for people with pulmonary hypertension, reducing the need for X-ray guidance.
What could go wrong
This is a small, early feasibility study with only 35 participants. The technique may not work well in all patients, and complications like catheter misplacement or arrhythmias are still possible.
