Pulsed Field Ablation vs Cryoablation for Atrial Fibrillation Under Deep Sedation

Official title: A Comparison of Pulsed Field Ablation (PFA) vs Cryoablation for Atrial Fibrillation Under Deep Sedation

Run by East Sussex Healthcare NHS Trust · NCT07900685 · Data updated 2026-11-12

This trial tests whether pulsed field ablation (PFA) done under deep sedation works as well as cryoballoon ablation for treating atrial fibrillation, aiming to avoid general anesthesia.

Is this trial a fit for you?

Likely a good fit

Adults over 18 with paroxysmal or persistent AF requiring a clinically indicated ablation and able to provide informed consent.

Probably not a fit

Patients with obesity-related airway issues, significant reflux or large hiatus hernia, or inability to tolerate the procedure under deep sedation may not benefit.

What this trial studies

In this interventional study, 60 adults with atrial fibrillation undergoing ablation are assigned 2:1 to receive either PFA or cryoballoon ablation. All procedures are performed under deep sedation with IV analgesics and sedatives; if needed, the PFA procedure can be converted to cryoballoon during the same session. The goal is to determine if deep-sedation PFA can be safely and effectively used without general anesthesia, potentially improving throughput and reducing costs. The study collects safety and efficacy data to establish a deep-sedation protocol for PFA during pulmonary vein isolation. If favorable, results could support broader adoption of deep sedation PFA in clinical practice.

Why it matters

Potential benefit: If successful, the protocol could reduce the need for general anesthesia during AF ablation, improve lab efficiency, and lower costs.

How similar studies have gone: Previous experiences in Europe suggest PFA is rapid and safe, but deep-sedation protocols in this context are being established.
