Fig. 3From: 3D electroanatomical mapping is less sensitive to atrial remodeling in estimation of true left atrial volume than echocardiographyDifferences between 2D-ECHO-based, CARTO-derived and CT-derived left atrial volumes according to remodeling of left atrium. Caption: Left atrium remodeling was defined according to sphericity index obtained from CT. Atrias were dichotomized according to median of sphericity index. The points and whiskers represent mean and ± standard deviation. Abbreviations as in Fig. 1Back to article page
