Abstract

Thus, LV volumes and ejection fraction obtained from 3-dimensional echocardiography using a multiplane TEE probe correlates highly with left ventriculography for estimation of LV volumes and ejection fraction. This suggests that this technique may be useful in the evaluation of LV function in the clinical setting.

3D transesophageal echocardiography: A new imaging tool for assessment of mitral regurgitation and for guiding percutaneous edge-to-edge mitral valve repair
2017, Progress in Cardiovascular Diseases
Real time three dimensional transesophageal echocardiography (3D TEE) is probably the most powerful and convincing imaging method for understanding the complicated multiform morphology and for evaluating geometry, dynamics and function of degenerative and functional mitral valve (MV) regurgitation. Moreover, color Doppler 3D TEE has been valuable to identify the location of the regurgitant orifice and the severity of the mitral regurgitation. 3D TEE has been shown to be of enormous value in helping surgeons to perform MV repair. In addition, due to its ability to show a “panoramic” view of the “theater” where the procedure takes place, it has become an indispensable companion of 2D TEE during percutaneous edge-to-edge repair. A novel hybrid imaging modality where echocardiography is merged with fluoroscopy, may in the future further improve guidance of this and other complex percutaneous transcatheter interventions.

Pattern and impact of altered regional myocardial excursion on global ventricular performance after first-time acute anterior wall myocardial infarction by real-time three-dimensional echocardiography
2008, International Journal of Gerontology
The regional wall motion score index obtained by two-dimensional echocardiography in myocardial infarction (MI) has a significant impact on left ventricular (LV) global contractility and is of extraordinary prognostic value, whereas data regarding real-time three-dimensional echocardiography (RT-3DE) are lacking. We sought to clarify the relationship between RT-3DE and LV contractility in patients after MI.
RT-3DE was performed in 50 patients with anterior wall acute myocardial infarction and 30 normal controls. Global (16 segments) and regional ring-based LV systolic excursions were analyzed offline using the commercially available software Q-Lab version 5.0. The correlations between the LV global and regional systolic excursions and the global LV contractile performance were examined in the MI patients, and further compared with the control group.
The global and regional (basal and middle ring-based) LV systolic excursions were lower in the MI patients (age, 61.8 ± 13.1 years) than in the normal controls (age, 40.0 ± 15.4 years). Global excursion showed inverse linear relationships with LV end-systolic volume (r =-0.26, p < 0.05) and end-diastolic volume (r =-0.22, p < 0.05) but no significant relationships with LV ejection fraction (p = 0.08) and stroke volume (p = 0.49).
Regional wall motion abnormalities quantified by RT-3DE are clinically convenient and feasible in both MI patients and the normal population. This rapid and objective quantification may also help discriminate abnormal from normal regional and global functions after infarction and, therefore, has the potential to be an attractive solution for clinical diagnosis.
Real-Time 3-Dimensional Echocardiographic Quantification of Left Ventricular Volumes. Multicenter Study for Validation With Magnetic Resonance Imaging and Investigation of Sources of Error
2008, JACC: Cardiovascular Imaging
We sought to study: 1) the accuracy and reproducibility of real-time 3-dimensional echocardiographic (RT3DE) analysis of left ventricular (LV) volumes in a multicenter setting, 2) interinstitutional differences in relationship with the investigators' specific experience, and 3) potential sources of volume underestimation.
Reproducibility and accuracy of RT3DE evaluation of LV volumes has not been validated in multicenter studies, and LV volumes have been reported to be underestimated compared to cardiac magnetic resonance (CMR) standard.
A total of 92 patients with a wide range of ejection fractions underwent CMR and RT3DE imaging at 4 different institutions. Images were analyzed to obtain LV end-systolic volume (ESV) and end-diastolic volume (EDV). Reproducibility was assessed using repeated analyses. The investigation of potential sources of error included: phantom imaging, intermodality analysis-related differences, and differences in LV boundary identification, such as inclusion of endocardial trabeculae and mitral valve plane in the LV volume.
The RT3DE-derived LV volumes correlated highly with CMR values (EDV: r = 0.91; ESV: r = 0.93), but were 26% and 29% lower consistently across institutions, with the magnitude of the bias being inversely related to the level of experience. The RT3DE measurements were less reproducible (4% to 13%) than CMR measurements (4% to 7%). Minimal changes in endocardial surface position (1 mm) resulted in significant differences in measured volumes (11%). Exclusion of trabeculae and mitral valve plane from the CMR reference eliminated the intermodality bias.
The RT3DE-derived LV volumes are underestimated in most patients because RT3DE imaging cannot differentiate between the myocardium and trabeculae. To minimize this difference, tracing the endocardium to include trabeculae in the LV cavity is recommended. With the understanding of these intermodality differences, RT3DE quantification of LV volume is a reliable tool that provides clinically useful information.
How accurately, reproducibly, and efficiently can we measure left ventricular indices using M-mode, 2-dimensional, and 3-dimensional echocardiography in children?
2008, American Heart Journal
Measurements of left ventricular (LV) size, mass, and function are the most common and important tasks for echocardiography in clinical practice and research in children with congenital and acquired heart diseases. There are little data to compare the utility of M-mode (MM), 2-dimensional (2D), and 3-dimensional (3D) echocardiographic techniques for quantification of LV indices. The objective of the study was to assess the accuracy, reproducibility, and efficiency of these echocardiographic methods for measurement of LV indices in children.
A prospective study was conducted in 20 consecutive children (mean 10.6 ± 2.8 years, 11 male and 9 female subjects) using conventional MM, 2D, and real-time 3D echocardiography (RT3DE). A Sonos 7500 system (Philips Medical Systems, Andover, MA) was used. M-mode and 2DE measurements were made according to the American Society of echocardiography recommendations. To include the entire LV for volumetric measurement, full-volume 3D data sets were acquired from 4 electrocardiogram gated subvolumes. The 3DE measurements were made off-line manually using 4-plane and 8-plane algorithms by 4D Echo-View (TomTec Imaging Systems, Munich, Germany) and a semiautomated algorithm by QLAB (Philips Medical Systems). Magnetic resonance imaging studies were also performed to determine the LV indices by a disk summation method based on the Simpson principle.
The correlation and agreement between MM, 2D, and RT3D echocardiography and magnetic resonance imaging measurements are good (r = 0.81-0.97) for the 3 methods. The correlation was superior for RT3DE compared with 2DE and MM. The correlation and agreement were similar for the three 3DE methods. The intra- and interobserver variabilities ranged from MM (4.3%-4.8% and 7.0%-8.7%), 2DE (3.3%-4.5% and 5.5%-7.3%), and 3DE (0.4%-2.3%, and 0.2%-4.8%). The total time (acquisition and analysis) used for MM measurements was the least compared with 2DE and 3DE. The total time for 3DE using the semiautomated algorithms was not significantly different compared with that for 2DE.
Our study showed that MM provides the most efficient assessment of LV indices but is the least accurate and reproducible technique compared with 2DE and 3DE. Three-dimensional echocardiography using both automated and manual analysis algorithm is superior to MM and 2DE for measurements of LV indices, and the automated 3DE algorithm is as efficient as 2DE. Therefore, 3DE using the automated algorithm is the method of choice for quantification of LV indices.

The cardiac structures are manually or semiautomatically traced to the 3D spatial coordinates to reconstruct a 3D image (Figure 1). Several studies have demonstrated that 3D reconstruction from serial 2D images provides accurate anatomic information suitable for quantitative analysis.4-8,10-15 However, this methodology is subject to technical limitations during image acquisition and requires significant offline data processing.
