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 This study
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 Results may not be published yet.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

Summary

This study looks at how well two types of replacement heart valves (balloon-expandable vs. self-expanding) work in Asian patients with a naturally small aortic valve opening. Researchers will track 31 people for one year to see which valve type leads to fewer complications and better blood flow. The goal is to find the best approach for this specific group.

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 could help doctors choose the best valve type for Asian patients with a small aortic valve opening, improving long-term results.
What could go wrong
This is a small, observational registry (31 participants) that only looks at existing data, so it cannot prove cause and effect. Results may not apply to all Asian groups.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Retrospective data collection will be carried out at multiple TAVI sites in Asia. Patients with severe AS who underwent TAVI (SEV/ BEV) will be identified from retrospective records (Physical/ Electronic). Consecutive patients who underwent pre-procedural computed tomography (CT) scans for aortic valve evaluation from 2018-1-1 to 2024-12-31 were included.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

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