A Left ventricular end systolic (LVESV) and end diastolic volumes (LVEDV) as determined by biplane transthoracic AutoEF (yellow) and TOE using the modified Simpson’s method (blue). Box-and-whiskers plots show the first (bottom), second (inner line indicating median), and third (top) quartile. The whiskers represent the limits of 1.5 times the interquartile range. Outliers are depicted as circles below and above these limits, asterisks represent extreme outliers. * p < 0.01. B Bland–Altman plot for comparison of left ventricular end diastolic volumes determined by biplane transthoracic AutoEF and TOE using the modified Simpson’s method. Bias: 29.8 ml, 95%LOA: -45.3 — 105 ml. Solid line represents bias, dashed lines show the 95% limits of agreement (95%LOA). C Bland–Altman plot for comparison of left ventricular end systolic volumes as determined by biplane transthoracic AutoEF and TOE using the modified Simpson’s method. Bias: 28.1 ml, 95%LOA: -18.2 – 74,5 ml. Solid line represents bias, dashed lines show the 95% limits of agreement (95%LOA). EF: ejection fraction, TOE: transoesophageal echocardiography, LVEDV: left ventricular end diastolic volume, LVESV: left ventricular end systolic volume
