This pilot, prospective, interventional, monocentric, independent, and no-profit clinical trial aims to investigate and evaluate the proportion, acute and chronic characteristics, and outcomes of esophageal thermal injury (ETI) in AF ablation using a high-power, short-duration (HP-SD) setting with contact force (CF) sensing tip ablation catheter in standard clinical practice. The main questions it aims to answer are: * Evaluate the acute proportion of the ETI assessed by the mini-invasive esophagoscopy pre and post-procedure. In addition, clinical evaluations at 3, 6, and 12 months from the procedure are foreseen. * Evaluate the contribution of the factors influencing RF procedure (contact force, impedance, RF power, RF time) on ETI development. * Describe the relationship between the esophageal temperature (continuous monitoring) and ETI development.
