“…This technique uses an ultrasound probe containing a matrix array of elements [18] yielding a three-dimensional pyramid-shaped volumetric data set. Three-dimensional echocardiography has been successfully employed in the measurement of LV function [19] and has been shown to be more reproducible than two-dimensional ultrasound [20]. In addition, using specialized post-processing software, regional ejection fraction can be calculated for each segment [19,21], as shown in Fig.…”

The role of cardiac ultrasound in evaluating and treating patients with stem cell therapy is reviewed. A number of ultrasound techniques can be used in the evaluation, therapy delivery, and follow-up of patients treated with stem cell therapy. These techniques include evaluation of myocardial systolic and diastolic function, perfusion, ischemia, viability, synchrony, and imaging targeted to specific cell types.

“…4 ,5 In patients with cardiomyopathies, the preconceived assumption of a normal LV shape used in calculation could lead to mistakes in quantifying volumes. 4,6 In the past, three-dimensional (3D) echocardiography was cumbersome and time consuming, limiting its application to research or studies outside the operating room. Recent technical improvements have allowed real-time assessments with faster and easier use of 3D echocardiography.…”

BACKGROUND Three-dimensional (3D) transesophageal echocardiography (TEE) technology is now widely used intraoperatively in cardiac surgery. Left ventricular (LV) measurements with 3D transthoracic echocardiography correlate better with cardiac magnetic resonance measurements compared with traditional two-dimensional (2D) transthoracic echocardiography. In this study, we compared intraoperative 3D TEE against 2D TEE regarding quantitative indices of LV function. METHODS We performed 2D TEE and 3D TEE examinations on 156 patients scheduled for elective cardiac surgery. Two-dimensional TEE images of midesophageal 4-, 2-chamber, and long-axis views were acquired. LV volumes and ejection fraction (EF) were calculated by Simpson's method. Three-dimensional full-volume images were recorded to calculate by a semiautomated procedure LV volumes (indexed to body surface area) and EF. 3D and 2D LV dimensions and function, image quality, time for acquisition/analyses, and reproducibility were compared by the Wilcoxon matched-pairs signed-ranks test. Pairwise differences between 3D and 2D data were compared using 95% prediction intervals (PIs) and Bland-Altman methodology. 3D volumes were also plotted against 2D volumes in scatter plots using a 3-zone error grid. RESULTS There was no significant difference between 3D and 2D in the estimation of EF (P = 0.227; median pairwise difference, -0.4% [95% PIs, -8.6% to 8.8%]). 3D LV indexed end-diastolic volumes (iEDVs) and end-systolic volumes (iESVs) were larger than 2D iEDVs (P < 0.001; median pairwise difference, 3.3 mL/m [95% PIs, -9.4 to 14.1 mL/m] and iESV: P < 0.001; median pairwise difference, 1.4 mL/m [95% PIs, -5.2 to 10.1 mL/m]). In the vast majority of cases (98.8% of cases for iEDV and 92.8% of cases for iESV), the difference between 2D and 3D TEE indexed volumes did not alter classification into normal, mildly to moderately dilated, or severely dilated volumes, as demonstrated by the 3-zone error grid analysis. Acquisition of 3D TEE image and analysis were not feasible in 4 patients (2.5%) for whom a quantitative 2D assessment of the LV was also impossible. 3D and 2D quality image was similar (P = 0.206). There was no difference in 3D versus 2D acquisition time (P = 0.805; pairwise difference = 2 seconds [95% PIs, -20 to 35 seconds]), but 3D analysis required more time (P < 0.001; pairwise difference = 117 seconds [95% PIs, 66 to 197 seconds]). Differences in repeated 3D versus 2D indexed volumes were not statistically significant, both considering interobserver reproducibility (iEDV: P = 0.125; pairwise difference, 0.26 ± 1.76 mL [95% PIs, -3.58 to 3.73 mL] and iESV: P = 0.126; pairwise difference, -0.16 ± 1.67 mL [95% PIs, -3.96 to 3.69 mL]) and intraobserver reproducibility (iEDV: P = 0.975; pairwise difference, -0.02 ± 1.20 mL [95% PIs, -2.32 to 2.08 mL] and iESV: P = 0.228; pairwise difference, -0.19 ± 1.13 mL [95% PIs, -2.47 to 2.53 mL]). CONCLUSIONS Intraoperative 3D TEE quantification of LV global function, image acquisition time, and reproducibility ...

“…In addition, the measurement of LV volumes using 3D echocardiography is one of the most useful aspects of this technique, with very good accuracy and reproducibility. [5][6][7] Cardiac magnetic resonance Cardiac magnetic resonance (CMR) is becoming more frequently used in the assessment of VHD. It provides quantitative and reproducible measures of both stenosis and regurgitation, as well as accurate measurement of the volume and function of both ventricles.…”
