Figure 1 Esophageal migration. The lumen of the esophagus (Eso) is visualized with barium paste. The position of the Eso before (A) and after (B) ablation is shown in the anteroposterior projection. In A, a left atrial mapping/ablation catheter and a quadripolar coronary sinus catheter (CS) are also shown.

Figure 2 Change in esophageal luminal diameter. There was a marked difference in esophageal diameter before (A) and after (B) the ablation procedure in the anteroposterior projection. The borders of the esophageal lumen are marked with arrows. CS = coronary sinus catheter; Eso = esophagus.

Figure 3 Visualization of the esophagus (Eso) in the anteroposterior projection. The position of the Eso was very similar before (A) and after (B) the ablation procedure. CS = coronary sinus catheter.
