Fig. 2

Left atrial cross-sectional largest areas and long axis lengths for left atrial volume calculation by area-length method. Left ventricular (LV) long axis-oriented left atrial (LA) images (top row) and LA long axis-oriented images (bottom row) at maximum LA volume. Calculated LA volumes are 52.6 mL (error − 38.8 mL) with LV oriented images and 93.8 mL (error + 2.4 ml) with LA oriented images. Same study subject as in Fig. 1. Planimetry area in LA oriented 2CH image is roughly twice the area in LV oriented 2CH view. 2CH two-chamber, 4CH four-chamber, LA2CH left atrium oriented two-chamber, LA4CH left atrium oriented four-chamber
