Mentions: Significant enhancement of the esophageal wall (EWE) as a sign of acute tissue reaction after ablation was found in 22 patients (39.3%). Local tissue reaction was independent from the type of Cryoballoon as EWE was detected in 33.33% in the AF and 47.87% of the AFA group (p = 0.275, Figure 1). EWE was related to the anatomical conditions of the esophagus as EWE was significant higher in those patients where the esophagus was in contact with the left or right inferior pulmonary veins compared to patients where the esophagus was in contact with the posterior wall of the LA (62.5% vs. 8.3%, p = < 0.001; Figure 2 and Figure 3). Anatomical location of the esophagus was unchanged in all patients comparing the pre and acute LGE-MRI.
