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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether measuring blood pressure inside the heart's left upper chamber during a procedure for atrial fibrillation (an irregular heartbeat) can spot patients with hidden heart failure. If the pressure is high, patients get a heart failure checkup and medication review within 24 hours. The study compares their outcomes to similar patients who received usual care, tracking medication use, heart function, and hospitalizations over three years.

What this could mean

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

Active substance
Structured heart failure consultation and medication optimization triggered by elevated left atrial pressure during atrial fibrillation ablation
What this could lead to
If it works, this approach could help identify hidden heart failure during a common heart procedure and start treatment earlier, potentially improving heart function and reducing hospitalizations.
What could go wrong
This is a relatively early study (300 participants) and the intervention is a care pathway, not a new drug. Results may not apply to all patients, and the benefit over standard care is uncertain.

Who can take part

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

Who is studied

Adults undergoing catheter ablation for atrial fibrillation at Froedtert Hospital, Medical College of Wisconsin, with intraprocedural mean left atrial pressure of 15 mmHg or greater measured immediately after transseptal puncture. The study includes a prospective pathway cohort (2024 onwards) and a historical standard-care cohort (2022-2023) meeting the same procedural and hemodynamic criteria.

Anyone

Healthy volunteers

Not accepted

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