Mentions: Gender differences were noted for atrial volumes and derived parameters. Maximal right atrial volume (RA) for girls was 53.3±11.8 ml/m2 and 58.1±15.7 for boys (p=0.064), minimal RA volume for girls/boys was 23.2±6.2/27.0±7.9 ml/m2 (p=0.004). Maximal left atrial (LA) volume for girls/boys was 44.2±8.7/46.7±10.1 ml/m2 (p=0.143) and minimal LA volume for girls/boys was 19.2±3.9/21.5±5.1 ml/m2 (p=0.009). For both atria, cyclic volume change (CVC) was higher for boys, but emptying fraction (EMF) higher for girls (p=0.03). Percentiles of RA/LA volumes showed steeper increase in boys than in girls, who in fact showed a plateau after age 14. Figure 1.
