Figures & Tables

Figure 1

Morphologies of the LAA. The categorization of LAA morphologies according to DiBiease et al. A: windsock: the primary structure is one dominant lobe with sufficient length B: chicken wing: the dominant lobe has an obvious bend in the proximal part C: cauliflower: LAA has limited length and the distal width exceed the proximal width D: swan: LAA has a second sharp curve folding the dominant lobe back13.

Differentiation between pseudothrombus (A-B) versus genuine thrombus (C-D). A: filling defect in the LAA. B: an affirmative delayed phase showing an empty LAA. This phenomenon is due to poor filling of the LAA with contrast secondary to venous stasis and/or left atrial dysfunction. C: a filling defect in the LAA. D: low attenuation filling defect in the delayed phase scan confirming the presence of LAA thrombus (Courtesy Heart and Vascular Center of Semmelweis University, Budapest, Hungary).
