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

Inclusion Criteria: 1\) Patients undergoing atrial fibrillation ablation using the Varipulse™ catheter Exclusion Criteria: 1. Individuals under 19 years of age 2. Patients who undergo concomitant radiofrequency ablation of the left atrium during the procedure 3. Patients with a history of stroke or transient ischemic attack (TIA) 4. Patients who have previously undergone ablation or surgery for atrial fibrillation 5. Patients with intracardiac thrombus or embolic events within the past 90 days 6. Patients who have experienced cardiac surgery or acute coronary syndrome within the past 90 days 7. Patients with contraindications to oral anticoagulant therapy, or those who require temporary discontinuation of anticoagulation due to procedural complications (e.g., cardiac tamponade) 8. Patients with a left ventricular ejection fraction (LVEF) of less than 35% 9. Women who are currently pregnant or planning to become pregnant during the study period 10. Patients with a life expectancy of less than one year 11. Patients at increased risk during MRI scanning (e.g., those with pacemakers or other metallic implants affected by MRI, or those with severe claustrophobia)
