A Prospective Observational Study Evaluating the Incidence of Silent Cerebral Lesions and Procedural Safety Following Atrial Fibrillation Ablation Using the VARIPULSE™ Pulsed Field Ablation System

This study is tracking how often small, silent brain lesions (tiny areas of brain injury that cause no symptoms) occur after a heart rhythm procedure called atrial fibrillation ablation using a new device called the VARIPULSE Pulsed Field Ablation System. Doctors want to make sure this newer procedure is as safe as older methods. **You may be eligible if...** - You are having atrial fibrillation (irregular heartbeat) ablation using the VARIPULSE catheter device - You are 19 years or older **You may NOT be eligible if...** - You have a history of stroke or TIA (mini-stroke) - You have previously had surgery or ablation on your heart for atrial fibrillation - There is a blood clot in your heart or you have had a clot-related event in the past 90 days - You had heart surgery or a heart attack in the past 90 days - You cannot safely take blood thinners - You have a pacemaker or other implanted cardiac device - You are pregnant Talk to your doctor to see if this trial is right for you.
