Prevalence and Predictors of Esophageal Thermal Lesions in High-power-Short-duration Ablation of Atrial Fibrillation

Patients with documented atrial fibrillation who were referred to our clinic for catheter ablation will undergo standard HPSD ablation and subsequent esophagoscopy.After esophagoscopy patients will be followed up for one month in the form of a telephone follow-up.The primary endpoint of the study assessed by esophagoscopy performed on the day after the index catheter ablaton is the incidence of esophageal thermal lesions.Secondary endpoints include:The size of the esophageal thermal lesions.The severity of esophageal thermal lesions.

Inclusion Criteria:Atrial fibrillation documented in the 12-lead ECGIndication for catheter ablation in accordance with currentn ESC guidelinesExclusion Criteria:PregnancyWomen of childbearing potential without a negative pregnancy test within 48 hours prior to ablation procedureKnown intracardiac or other thrombiContraindication to anticoagulationContraindication to esophagoscopy: diseases and deformities of the cervical spine, esophageal varices
