Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Description of intervention(s) / exposure
Catheter ablation is an atrial fibrillation treatment that is done by a specialized cardiologist, called an electrophysiologist (EP), who deals with irregular heartbeats (arrhythmias).
It is a minimally-invasive procedure that is generally less invasive than surgery. It is a commonly-used treatment for atrial fibrillation as well as other cardiac arrhythmias.
It is done on a beating heart in a closed chest procedure. Small punctures are made in the groin and the catheters, are inserted and threaded to the heart. Once there, the catheter's tip is threaded through a tiny incision in the wall between the left and right atria (septal wall), and is positioned to ablate tissue around the pulmonary veins or at other sources of erratic electrical signals that cause the irregular heartbeat.
The catheter uses an energy source, such as radio frequency energy (radio waves) to create a lesion of scar tissue, called a conduction block, that stops the erratic electrical signals from travelling through the heart.
The procedure usually takes around 2 to 4 hours per patient.
The ElePulse system which is used in this study is an electroporation ablation system. It uses pulsed field energy to selectively destroy cardiac tissue and thus stop aberrant electric conduction in the heart. This is called Pulsed Field Ablation (PFA). The ElePulse catheter is connected to the ElePulse PFA generator which creates the electric field used to ablate the heart tissue.
A remap procedure will be performed at 3 months after the completion of the ablation procedure. During this procedure it will be determined whether the success of the first procedure was durable. The remap procedure is comparable in duration to the initial procedure. If the first procedure is not considered adequate, a re-ablation may be performed during the remap procedure.
