“…The value of RT3DE imaging in this context has been demonstrated by multiple studies that compared RT3DE volume measurements with widely accepted reference techniques, including radionuclide ventriculography and cardiac magnetic resonance (CMR). [2][3][4][5][6] These studies and others have demonstrated higher levels of agreement between the RT3DE approach and the respective reference technique compared with conventional 2DE methodology. Additionally, RT3DE measurements were found to be more reproducible than 2DE 4,5,7 and, in some studies, even as reproducible as CMR.…”

O ne of the most significant developments of the last decade in ultrasound imaging of the heart was the evolution of 3-dimensional (3D) imaging from slow and labor-intense offline reconstruction to real-time volumetric imaging. This imaging modality provides valuable clinical information that empowers echocardiographers with new levels of confidence in the diagnosis of heart disease. We have previously described the technological milestones in the development of real-time 3D echocardiographic (RT3DE) imaging and its major advantages over conventional 2-dimensional echocardiography (2DE) and reviewed the published literature that supported the use of this new methodology in clinical practice. 1 Since 2006, the growing availability of RT3DE technology, its ease of use, and its multiple attractive features have sparked significant interest in the research community, resulting in a large number of publications, most of which have endorsed RT3DE imaging for clinical use by demonstrating its unique capabilities in different scenarios. In parallel, the clinical acceptance of this new tool has broadened significantly. The most recent clinically significant addition is matrix-array transesophageal echocardiography (TEE), which provides images of unprecedented quality that aid surgeons and interventional cardiologists in planning and guiding procedures and evaluating their outcomes.The purpose of the present article is to review the most recent RT3DE literature and provide readers with an update on the latest developments and the current status of this noninvasive imaging tool. Because different potential applications of RT3DE imaging have been explored to various extents, they are described here separately, and each is discussed with an emphasis on the scientifically established facts, along with the known stumbling blocks and difficulties. Quantification of LV Volumes and FunctionA firmly established advantage of 3D imaging over crosssectional 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 abnormalities, and the errors caused by foreshortened views even in symmetrical ventricles. The value of RT3DE imaging in this context has been demonstrated by multiple studies that compared RT3DE volume measurements with widely accepted reference techniques, including radionuclide ventriculography and cardiac magnetic resonance (CMR). [2][3][4][5][6] These studies and others have demonstrated higher levels of agreement between the RT3DE approach and the respective reference technique compared with conventional 2DE methodology. Additionally, RT3DE measurements were found to be more reproducible than 2DE 4,5,7 and, in some studies, even as reproducible as CMR. 8 Interestingly, in a recent study in patients after myocardial infarction (MI), 9 RT3DE-derived LV volumes were more accurate and more reproducible than thos...

“…The frequently observed shortening following systole with these two methods causes the term "peaking time" to become more complicated. MRI is considered the gold standard for assessing cardiac shape and function, and other modalities such as real-time three-dimensional echocardiography (RT-3DE) (39,40), closely correlate with MRI. Dyssynchrony using tissue Doppler images (TDI) during the acute phase of myocardial infarction is also considered a predictor of LV remodeling (3,41) and although RT-3DE can be used to assess cardiac dyssynchrony (42), few reports have been published and the results do not coincide with those of TDI (43).…”

Objective: The aim of this study was to prospectively evaluate the effect of percutaneous coronary intervention in the acute period on left ventricular dyssynchrony in ST-segment elevation myocardial infarction patients by using Tissue Synchronization Imaging. Methods: Forty-four ST-segment elevation myocardial infarction (MI) patients (29 male, 15 female), who were admitted within the first 12 hours of chest pain symptoms, were enrolled in the study. According to the localization of MI, the patients were divided into groups as anterior MI (n=26) and inferior MI (n=18). All echocardiography measurements were taken just before percutaneous coronary intervention (PCI) and following PCI at a mean of 3-6 days. They were assessed according to the time to reach the peak systolic velocity, which was calculated by the tissue synchronization imaging method from four pairs of non-apical alternate segments. The difference between the duration to reach the peak systolic velocity in alternate segments was regarded as left ventricle dyssynchrony and the results were compared. Results: In the anterior MI group, basal anterior (p<0.01), mid-anterior segment (p<0.01) and basal septal segment (p<0.01); in the inferior MI group, the basal septal segment (p=0.02), mid-septal segment (p=0.02), and basal and mid-inferior segment (p<0.01) values were significantly lower in the post-PCI measurements when compared to the measurements taken prior to PCI. In both groups, the intraventricular dyssynchrony indices of the basal anterior-basal inferior (p<0.01), mid-anterior-mid-inferior (p<0.01) segments were found to be significantly lower in the post-PCI period when compared to the pre-PCI period. Conclusion: It was found that percutaneous coronary intervention in patients with ST-elevation significantly decreases the degree of LV dyssynchrony in the acute period.
