“…23 Moreover, volumetric measurements of LV mass were found to correlate highly with CMR reference values in patients with wall motion abnormalities 8 and in patients with abnormally shaped ventricles secondary to congenital heart disease. 24 Although the former study described a considerable negative bias, the latter reported only minimal biases. Similar to the inconsistencies with LV volume measurements, these differences are likely to be due to differences in strategies for identifying and tracing the endocardial and epicardial boundaries.…”

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...

“…Despite the availability of more accurate, but complex, biplanar and three-dimensional echocardiographic methods to measure heart function (1,4), basic M-mode and two-dimensional echocardiography (2D-echo) are the most commonly used techniques (2,(5)(6)(7)(8)(9)(10)(11)(12)(13). The major limitations of 2D-echo are the small acoustic window through which the acquisitions can be made (14), the need for a skilled operator (15), and assumptions that are made about left ventricular geometry (16,17), which become problematic in the asymmetrical left ventricle after myocardial infarction (1,14,18).…”

Cine‐MRI versus two‐dimensional echocardiography to measure in vivo left ventricular function in rat heart

et al. 2008

Two-dimensional echocardiography is the most commonly used non-invasive method for measuring in vivo cardiac function in experimental animals. In humans, measurements of cardiac function made using cine-MRI compare favourably with those made using echocardiography. However, no rigorous comparison has been made in small animals. Here, standard short-axis two-dimensional (2D) echocardiography (2D-echo) and cine-MRI measurements were made in the same rats, both control and after chronic myocardial infarction. Correlations between the two techniques were found for end diastolic area, stroke area and ejection fraction, but cine-MRI measurements of ejection fraction were 12+/-6% higher than those made using 2D-echo, because of the 1.8-fold higher temporal resolution of the MRI technique (4.6 ms vs 8.3 ms). Repeated measurements on the same group of rats over several days showed that the cine-MRI technique was more reproducible than 2D-echo, in that 2D-echo would require five times more animals to find a statistically significant difference. In summary, caution should be exercised when comparing functional results acquired using short-axis 2D-echo vs cine-MRI. The accuracy of cine-MRI allows identification of alterations in heart function that may be missed when using 2D-echo.

“…So, there were significant differences between LVRI detected by RT3DE and 2DE in HHD and CAD groups, and had significant different correlations. Therefore, we could concluded that LVRI detected by RT3DE was superior to LVRI detected by 2DE according to the principles of RT3DE and 2DE, previous studies [5,6,[18][19][20][21][22][23][24] , and this study combined.…”

“…Previous studies showed that conventional transthoracic 2DE was not ideal for accurate quantification of left ventricular volume for its subject to image-plane positioning errors, or left ventricular was distorted in shape after acute myocardial infarction, or left ventricle developed aneurysm in myocardial infarction [13][14][15][16] . On the contrary, for recent advances in capability of new combination of ultrasound system, computer processing and commercial software, RT3DE has resolved many of the limitations associated with the evaluation of left ventricular volume from 2DE images and significantly improved the accuracy of these measurements [17] , and provided fast, accurate and available assessment of left ventricular volume, left ventricular mass without geometric assumptions, which resulted in higher levels of agreement and reproducibility with the CMR reference values [5,6,[18][19][20][21][22][23][24] . Moreover, left ventricular cavity remodeled often developed dilation, distortion, or regional abnormal wall motion, even developed many abnormal changes in one cardiac cycle [25] , which caused left ventricular morphology departure from geometric assumption model.…”

Left ventricular remodeling index (LVRI) was assessed in patients with hypertensive heart disease (HHD) and coronary artery disease (CAD) by real-time three-dimensional echocardiography (RT3DE). RT3DE data of 18 patients with HHD, 20 patients with CAD and 22 normal controls (NC) were acquired. Left ventricular end-diastolic volume (EDV) and left ventricular end-diastolic epicardial volume (EDVepi ) were detected by RT3DE and two-dimensional echocardiography Simpson biplane method (2DE). LVRI (left ventricular mass /EDV) was calculated and compared. The results showed that LVRI measurements detected by RT3DE and 2DE showed significant differences inter-groups (P<0.01). There was no significant difference in NC group (P>0.05), but significant difference in HHD and CAD intra-group (P<0.05). There was good positive correlations between LVRI detected by RT3DE and 2DE in NC and HHD groups (r=0.69, P<0.01; r=0.68, P<0.01), but no significant correlation in CAD group (r=0.30, P>0.05). It was concluded that LVRI derived from RT3DE as a new index for evaluating left ventricular remodeling can provide more superiority to LVRI derived from 2DE.
