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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 pilot study compares two ablation techniques for treating ventricular tachycardia, a fast and dangerous heart rhythm that can occur after a heart attack. Researchers will randomly assign 40 adults with ischemic heart disease and an implantable defibrillator to receive either pulsed field ablation (PFA) with the FARAPOINT catheter or standard radiofrequency ablation (RFA). The goal is to see whether PFA can eliminate the abnormal heart tissue more quickly while keeping the same safety profile as the standard method.

What this could mean

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

Active substance
Pulsed field ablation (PFA) using the FARAPOINT catheter, compared with standard radiofrequency ablation (RFA) using FlexAbility or ThermoCool ST catheters
What this could lead to
If PFA works as hoped, it could shorten ablation procedures for dangerous heart rhythms after a heart attack, while keeping safety on par with the standard approach.
What could go wrong
This is a small pilot study, so results may not hold up in larger trials. PFA is newer and could carry unexpected risks, such as heart damage or rhythm complications.
