Margot Sommer et al. JIMG 2015;8:1107-1110 Comparison of LAA Morphology in CT Reconstruction and 3D TEE LAA computed tomography (CT) angiography was performed on a 128-slice CT scanner (SOMATOM Definition AS+, Siemens, Forchheim, Germany) with administration of iomeprol 400 mg iodine/ml (Iomeron 400 MCT, Bracco Imaging, Milan, Italy). (A) 3D reconstruction was rendered at a post-processing workstation (syngo.via version 11, Siemens Healthcare, Erlangen, Germany). (B) 3D TEE methodology is described in the legends for Figures 1 and 2. The agreement in differentiating all 4 LAA types showed promising results in CT versus 3D TEE: LAA type: κ = 0.83, p < 0.001; number of lobes: r = 0.88, p < 0.001 (n = 33). Interobserver agreement was good for classification in chicken wing versus non–chicken wing LAA (each κ = 93, p < 0.001) and in assignment of all 4 LAA types (CT: κ = 0.87, p < 0.001; 3D TEE: κ = 0.85, p < 0.001). Agreement in number of lobes was good in CT (r = 0.73, p < 0.001) and fair in 3D TEE (r = 0.59, p < 0.001). Abbreviations as in Figure 1. Margot Sommer et al.
