Evaluation of the luminal esophageal temperature behavior during left atrium posterior wall ablation by means of second-generation cryoballoon

Purpose The purpose of this study was to clarify the behavior of the luminal esophageal temperature (LET) in a cohort of patients undergoing second-generation cryoballoon (CB-A) for pulmonary vein isolation (PVI) and additional left atrium posterior wall (LAPW) ablation by means of CB-A.
