LV end-systolic volumes showed moderate correlations with 3D strain parameters: 3D longitudinal strain (r = −0.30, P < 0.001), 3D circumferential strain (r = −0.46, P < 0.001), .
LA volume, only the mean value and the SD of gender-, age-, and body surface area (BSA)–normalized cutoffs or upper and lower limits are reported in the appropriate sections of . Measurements included LV end-diastolic and end-systolic volumes, LV ejection fraction (LVEF), global longitudinal strain (GLS), and global circumferential strain. Results .

Assessment of LV volumes using 2D echocardiography is limited by foreshortening, malrotation, angulation, and reliance on geometric assumptions for volume calculation, resulting in an . Normal Values of Left Ventricular Size and Function on Three-Dimensional Echocardiography: Results of the World Alliance Societies of Echocardiography Study - .The improved accuracy of 3DE chamber quantification resulted in larger normal values of LV volumes, more similar to magnetic resonance reference values than those previously reported for 2DE . This advantage brought 3DE .
The NORRE study provides applicable 3D echocardiographic reference ranges for LV function assessment. Our data highlight the importance of age- and gender-specific . Real-time three-dimensional echocardiography (RT3DE) provides a more representative realistic view of LV volumes, thereby being the Necker cube for the naive . LV end-systolic volumes showed moderate correlations with 3D strain parameters: 3D longitudinal strain (r = −0.30, P < 0.001), 3D circumferential strain (r = −0.46, P < 0.001), 3D tangential strain (r = −0.44, P < 0.001), and 3D radial strain (r = −0.49, P < 0.001).
LA volume, only the mean value and the SD of gender-, age-, and body surface area (BSA)–normalized cutoffs or upper and lower limits are reported in the appropriate sections of this document. Measurements included LV end-diastolic and end-systolic volumes, LV ejection fraction (LVEF), global longitudinal strain (GLS), and global circumferential strain. Results were categorized by age (18-40, 41-65, and >65 years), sex, and race. Background: Left ventricular (LV) efficiency is a key pathophysiological marker in heart failure (HF). LV pressure curve estimation and three-dimensional (3D) volumes via echocardiography allows for non-invasive pressure-volume (PV) analysis and calculation of an index of efficiency (Figure 1). Aim: Validate efficiency index by 3D echocardiography by . For assessment of left ventricular (LV) and right ventricular (RV) morphology and function, three acquisition modes can be chosen: (1) simultaneous multiple two-dimensional (2D) planes, (2) live or single-beat 3D full-volume (large volume), and (3) .
Assessment of LV volumes using 2D echocardiography is limited by foreshortening, malrotation, angulation, and reliance on geometric assumptions for volume calculation, resulting in an underestimation of ventricular volumes. 4 With the 3D method, LV volumes can be measured without geometric assumption and are not affected by foreshortening .

Recommendations for Cardiac Chamber Quantification by
The improved accuracy of 3DE chamber quantification resulted in larger normal values of LV volumes, more similar to magnetic resonance reference values than those previously reported for 2DE . This advantage brought 3DE measurements of LV volumes into the clinical arena, with a potential to replace 2DE measurements of ventricular dimensions. The NORRE study provides applicable 3D echocardiographic reference ranges for LV function assessment. Our data highlight the importance of age- and gender-specific reference values for both LV volumes and strain. Real-time three-dimensional echocardiography (RT3DE) provides a more representative realistic view of LV volumes, thereby being the Necker cube for the naive realism of 2D methods. The Necker cube (Fig. 1a) is an optical illusion first published by the Swiss crystallographer Louis Albert Necker in 1832 [1]. LV end-systolic volumes showed moderate correlations with 3D strain parameters: 3D longitudinal strain (r = −0.30, P < 0.001), 3D circumferential strain (r = −0.46, P < 0.001), 3D tangential strain (r = −0.44, P < 0.001), and 3D radial strain (r = −0.49, P < 0.001).
