Abstract:Background: Active esophageal cooling during pulmonary vein isolation (PVI) with radiofrequency (RF) ablation for the treatment of atrial fibrillation (AF) is increasingly being utilized to reduce esophageal injury and atrioesophageal fistula formation. Randomized controlled data also show trends towards increased freedom from AF when using active cooling. This study aimed to compare one-year arrhythmia recurrence rates between patients treated with luminal esophageal temperature (LET) monitoring versus activ… Show more
