Figure 1. Three-dimensional computed tomography revealed that the patient’s esophagus (green) was tapered and became hypercontractile like a jackhammer (yellow arrows). The colored tags indicate ablation lines. LA = left atrium, LSPV = left superior pulmonary vein, LAPV = left inferior pulmonary vein, RSPV = right superior pulmonary vein, RIPV = right inferior pulmonary vein.
