Current echocardiographic guidelines recommend the use of 3-D echocardiography (in laboratories experienced in the use of this technique) to .For 3D Lv imaging, three different modes can be applied using a vendor-specific transducer (Table 22.1). Switching the probe from 2D to 3D is necessary for GE or Siemens 3D TTE; continuous 3D imaging following 2D without changing transducers works with all 3D transesophageal probes and the Philips 3D .

Three-dimensional echocardiography (3-DE) is a promising new method for assessing LV volumes and EF in patients with structural heart disease.
Three-dimensional echocardiography has shown to be an accurate and reproducible method for LV quantitation, mainly by avoiding the use of geometric assumptions. In this review, we describe various methods to acquire a 3D-dataset for LV volume and wall motion analysis, including their advantages and limitations. A firmly established advantage of 3D imaging over cross-sectional slices of the heart is the improvement in the accuracy of the evaluation of left ventricular (LV) volumes and .
Three-dimensional echocardiography (3DE) imaging has permitted advancements in the quantification of left ventricular (LV) and right ventricular (RV) volumes and ejection .
Current echocardiographic guidelines recommend the use of 3-D echocardiography (in laboratories experienced in the use of this technique) to assess LV volume and systolic function (Figure 2F). 6 This technique allows acquisition of the entire LV in a single volumetric data set using either single-beat or multibeat acquisitions.
3d rv volume calculation
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) .
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).Global Longitudinal Strain is a new parameter to assess LV systolic function. LV Volumes used to calculate EF Volumes can be derived from 2DE or 3DE (see section on LV size for methodology). o The biplane method of disks is the preferred 2DE method. o In laboratories with 3D experience, three-dimensional volumes should be utilized.
Due to its lower test-retest variability, 3D echo derived LV volumes and ejection fraction are ideally suited for serial monitoring of LV function. Changes in LV volumes assessed by serial 3D echo showed better correlations than that obtained with CMR .Results: LV end-systolic and end-diastolic volumes were underestimated by 2D and 3D unenhanced echocar-diography compared with cardiac magnetic resonance. Contrast enhancement resulted in similar significant increases in LV volumes on 2D and 3D echocardiography.

A firmly established advantage of 3D imaging over cross-sectional slices of the heart is the improvement in the accuracy of the evaluation of left ventricular (LV) volumes and ejection fraction (EF) by eliminating the need for geometric modeling, which is inaccurate in the presence of aneurysms, asymmetrical ventricles, or wall motion abnormalit. The main findings of this study are as follows: (1) LV volumes are larger in men than in women, even after indexing to BSA, (2) LV volumes are smaller in older age groups, (3) LVEF is higher in women than in men and tends to be higher in older age groups, (4) 3D LV GLS and GCS are higher in magnitude in women than in men, and (5) there are .Current echocardiographic guidelines recommend the use of 3-D echocardiography (in laboratories experienced in the use of this technique) to assess LV volume and systolic function (Figure 2F). 6 This technique allows acquisition of the entire LV in a single volumetric data set using either single-beat or multibeat acquisitions.
