- Coefficient of determination (R2) to evaluate the influence of age on left atrial (LA) maximum (LAMax) and minimum (LAMin) volume as well as on the ejection fraction (EF) and stroke volume (SV) in 50 healthy cats measured with 7 echocardiographic methods: right parasternal 4 chamber view measured with 2D Area/Length method (R4AL) and 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
