Figure 1 . Anatomical analysis of the relationship between the LA roof and esophagus based on CT. The three-dimensional CT method used to examine the anatomical relationship between the LA roof and esophagus is depicted. LA roof height from the point where the LAPW and esophagus make contact (a) and the distance between the LA roof and esophagus (b) were measured in the sagittal view. The orange line in the sagittal view represents the horizontal line that passes over the point where the LAPW and esophagus make contact. The orange lines in the coronal and axial views represent the position of the plane shown in the sagittal view.
CT, computed tomography; LA, left atrial; LAPW, left atrial posterior wall.
