Table 3 Differences in the left atrium and left atrial appendage dimensions as well as left atrial appendage morphological types between males and females

From: The left atrial appendage morphology and gender differences by multi-detector computed tomography in an Egyptian population

  Sex

Left atrial volume, ml (mean ± SD) 97.76 ± 28.73 97.82 ± 35.21 0.988
LAA volume, ml (mean ± SD) 7.47 ± 3.44 8.56 ± 4.09 0.026
LAA length, mm (mean ± SD) 40.02 ± 6.86 37.91 ± 8.93 0.038
LAA orifice position (N, %) Low 76 (46.3%) 50 (56.8%) < 0.01
Mid 76 (46.3%) 12 (13.6%)
High 12 (7.4%) 26 (29.6%)
LAA morphology (N, %) Windsock 52 (31.7%) 30 (34.1%) < 0.01
