Esophageal Temperature Dynamics and Injury During Pulmonary Vein Isolation With Temperature Controlled Very-High-Power Short-Duration Lesions Using the Novel Q-DOT Micro Ablation Catheter

This is a prospective randomized controlled trial, studying patients undergoing ablation involving pulmonary vein isolation for paroxysmal atrial fibrillation. Patients will be assigned to undergo conventional high-power short-duration ablation or temperature-controlled very-high-power short-duration ablation, and esophageal outcomes including temperature changes during ablation and esophageal injury as assessed by post-procedure capsule endoscopy will be compared between the groups. The hypothesis is that very-high-power short-duration ablation will lead to lower rises in esophageal temperatu…
