A Global Study Comparing Pulsed Field Ablation With Electrographic Flow Mapping Versus Posterior Wall Ablation for Persistent Atrial Fibrillation

A Global Randomized Trial Comparing Pulsed Field Ablation of Pulmonary Veins Plus Extra-PV Sources Utilizing Electrographic Flow Mapping Versus Pulmonary Veins Plus Posterior Wall in Persistent Atrial Fibrillation Patients.


Sponsor

Boston Scientific Corporation

Enrollment

699 participants

Start Date

Nov 7, 2025

Study Type

INTERVENTIONAL

Conditions

Summary

The purpose of this study is to establish the safety of the pulsed field ablation (PFA) therapy of Pulmonary Veins and Electrographic Flow (EGF) identified extra-PV sources of atrial fibrillation (PVI + EGF ablation of sources) and to demonstrate its non-inferiority in effectiveness compared to PFA of Pulmonary Veins and LA Posterior Wall (PVI+ PWA) in the treatment of de novo symptomatic drug-refractory persistent atrial fibrillation (PersAF).


Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This study is comparing two ablation techniques for treating persistent atrial fibrillation (AF), a heart rhythm disorder where the upper chambers of the heart beat irregularly. It compares a technique called pulsed field ablation with electrographic flow mapping versus posterior wall ablation to see which better restores normal heart rhythm. **You may be eligible if...** - You are 18 or older - You have ongoing AF for more than 7 days but less than 1 year - Your AF symptoms have not improved with at least one drug - You are willing to have a small heart monitor inserted under the skin **You may NOT be eligible if...** - Your left atrium (upper heart chamber) is very large - You have had previous heart or lung procedures related to AF - You have a blood clot in the heart, a heart tumor, or a serious valve problem - Your AF is caused by thyroid disease, electrolyte problems, or alcohol Talk to your doctor to see if this trial is right for you.

Interventions

DEVICEFARAPOINT Pulsed Field Ablation System

A component of the FARAPULSE Pulsed Field Ablation (PFA) System and is a multi-electrode bidirectional, deflectable percutaneous catheter, an adjunctive catheter designed to create focal-type lesions for the creation of an ablation line between the inferior vena cava and the tricuspid valve.

DEVICEOptiMap System (non-ablative)

An electrophysiology mapping system that uses a proprietary algorithm to analyze electrogram signals.

DEVICEFARAPULSE Pulsed Field Ablation (PFA) System and Opal HDx Mapping System

All subjects will undergo electroanatomical mapping of the entire left atrium with the FARAWAVE NAV Catheter and Opal HDx Mapping System, followed by PFA PVI with the FARAWAVE NAV PFA Catheter, per the instructions of use.
