- Inter- and intraobserver variability for left atrial maximum (LAMax) and LA minimum (LAMin) expressed as coefficient of variation (CV) in percent (%). LAMax and LAMin were measured with 6 echocardiographic methods: 2D monoplane Simpson method of discs (R4), left apical two chamber view (L2) and four chamber view (L4) measured with 2D monoplane Simpson method of discs, L2 and L4 combined to biplane volumetry (Biplane), Real Time Triplane Echocardiography (RTTPE) and 4D-TomTec™ analysing software
