  1. (Note VR① refers to the measurement on the VR image of an independent LA remodeling; VR② refers to the measurements on the VR image of the cardiac valves pattern; MPR① refers to the measurement at the ultrasonic plane; MPR② refers to the measurement at the apical two-chamber and four-chamber plane; MPR③ refers to the measurement at the orthogonal plane; MPR④ refers to the measurement at the oblique axis plane; MPR③a of the anteroposterior diameter means measurement at the orthogonal axis plane; MPR③b of the anteroposterior diameter refers to the measurement at the orthogonal sagittal plane; MPR③a of the long diameter refers to the measurement at the coronal plane; MPR③b of the long diameter refers to the measurement at the sagittal plane; VR①a of the transverse diameter refers to the distance between the inner and outer lateral walls of LA; VR①b of the transverse diameter suggests that the minimum distance of the extension line between the left and right PV orifices represents the transverse diameter.)
