Figure 1. Differences in Epicardial Adipose Tissue Volume Among Patients
without and with Epicardial Connection
Representative samples of computed tomography images of epicardial
adipose tissue (EAT, indicated in dark red) in a patient (A) without
epicardial connection and (B) with epicardial connection. The images are
shown in the sagittal plane at the level of the intercaval area (left
panel), in the axial plane at the level of the right pulmonary vein
carina (mid panel), and in the coronal plane at the level of the right
pulmonary vein carina (right panel). Note that in the upper image of
patients without epicardial connection, the EAT volume in the intercaval
area is larger (indicated by a white arrow in the upper panel) than that
of patients with epicardial connection (indicated by a white arrow in
the lower panel). The comparison of periatrial and intercaval EAT
volumes between the two groups are shown in (C). EAT = epicardial
adipose tissue; PA = pulmonary artery; RS = right superior pulmonary
vein; RI = right inferior pulmonary vein; Ao = aorta; RA = right atrium;
RV = right ventricle; LAA = left atrial appendage.
