Pulsed Field Ablation for Ventricular Tachycardia After Heart Attack

This study, called ASCEND, is looking at a new way to treat ventricular tachycardia (VT), a fast and irregular heartbeat, in people who have had a heart attack. It compares a new treatment called Pulsed Field Ablation (PFA) using the FARAPOINT catheter to the standard treatment, Radiofrequency Ablation (RFA), using catheters like FlexAbility or ThermoCool ST. The study wants to see if PFA is more effective at treating VT while being just as safe as RFA. You might be able to join if you are 18 or older, have ischemic heart disease (heart disease due to narrowed arteries) from a past heart attack, and have a certain heart pumping strength (ejection fraction) and documented sustained VT. The study aims to enroll 40 participants.

Study design
This is a pilot study that will randomly assign 40 participants to receive either Pulsed Field Ablation (PFA) or Radiofrequency Ablation (RFA). It is an open-label study, meaning both you and your doctors will know which treatment you are receiving.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
The study will measure procedural safety within 7 days after the procedure.
