Calculation of left atrial volume and function. The left atrial endocardial contour (orange curve) was delineated and the long and short diameters (yellow line) of the LA were measured at the end of left ventricular systole (A1,2), before left atrial systole (B1,2) and end of left ventricular diastole (C1,2) of the four-chamber long axis (A1, B1, C1) and two-chamber long axis (A2, B2, C2) images of CMR slices. And the left atrial volume (LAV) and left atrial emptying fraction (LAEF) according to the formula. a: the short diameter of the left atrium; b: the long diameter of the left atrium; L: the shorter length of the long axis of the left atrium in two-chamber or four-chamber cardiac planes
