Fig. 2
Balanced turbo field-echo short axial view of the right atrial appendage aneurysm. The well-defined, thin-walled right atrial appendage aneurysm can be seen compressing and deforming the right ventricle. Epicardial fat is seen between the right atrial appendage and the right ventricle (asterisk). The right atrial appendage aneurysm remains unchanged in size during a diastole and b systole, indicating an absence of contraction. The signal intensity in the aneurysm is lower than that of the blood pool in the right and left ventricles due to slow flow. A, RAA aneurysm; RV, right ventricle; LV, left ventricle
