Pulmonary Vein Isolation With the Single Shot Endoscopic Ultra-Compliant PFA Balloon for the Treatment of AF

This study is testing a new balloon-based procedure for treating paroxysmal atrial fibrillation (AF) — a condition where the heart beats irregularly in sudden episodes. The procedure uses a technique called pulsed field ablation (PFA), which uses energy pulses delivered through a balloon to disconnect the electrical triggers in the heart that cause AF. **You may be eligible if...** - You have recurring symptomatic atrial fibrillation with at least one documented episode - At least one anti-arrhythmia medication has not worked or has caused side effects - You are between 18 and 75 years old - Your doctor has recommended an ablation procedure for your AF - You are willing and able to participate in follow-up visits **You may NOT be eligible if...** - You have other serious health conditions that would make the procedure unsafe - You have had prior heart ablation procedures (depending on study specifics) - You have structural heart problems that would interfere with the balloon procedure - You are pregnant Talk to your doctor to see if this trial is right for you.
