“…The volume data sets were acquired with a standard acquisition time of 12.5 seconds and 25‐degree angle, and data sets were stored for further offline analysis . The HD Live technology was later applied to the stored volume data sets, and the AV valves and interventricular septal (IVS) anatomy were looked into . Informed consent was obtained from all of the cases included in the study, and the study was approved by the local ethics committee.…”

“…The standard echocardiographic planes can be displayed both in a frozen state and with the heart in motion, and because there is 3D information behind each frame, the scan plane can be moved and rotated (see Video Clip A1). By using the adjustable virtual light source in HD Live technology, lighting and shadowing effects were created, thereby increasing the depth perception in the stored volume data sets …”

“…This combination of light and shadows created by the virtual light source provides unique depth perception, producing remarkable images that are more realistic and natural than those obtained with classic 3D ultrasound . So far it has been used to visualize fetal face, limbs, and various surface anomalies, but recent studies have used it in the study of fetal heart . The HD Live technique provides a vivid illustration of atrioventricular (AV) valve anatomy and ventricular septal defects.…”

HDLive is a rendering methodology that generates realistic images of the human fetus from sonographic data. The objective of this study is to demonstrate the utility of high-definition live in evaluating fetal heart especially in the first trimester (11-14-week) scan. The normal atrioventricular valve and its abnormalities along with septal defects can be vividly demonstrated with this technique, and eight cases with cardiac defects are illustrated. Its use in the first-trimester evaluation of heart would give a better perspective of the cardiac malformation, which provides the opportunity for counseling options early in pregnancy.

“…This new algorithm makes it possible to assess the standard fetal echocardiography views like the four-chamber and ventricle outflow views (Figure 6). 45 Furthermore, this technique enables reconstruction of the entire fetal heart and its connections. A recent study assessed four normal and three abnormal fetal heart conditions (Ebstein’s anomaly, hypoplastic left heart syndrome, and tetralogy of Fallot) 46.…”

The objective of this review was to demonstrate the main tools of three- and four-dimensional ultrasonography, using the spatiotemporal image correlation software and its respective applications for assessing the fetal heart and its vascular connections, along with its potential contribution towards screening for congenital heart diseases. Today, conventional, two-dimensional, echocardiography continues to be the gold standard for diagnosing congenital heart diseases. However, recent studies have demonstrated that spatiotemporal image correlation offers some advantages that boost two-dimensional accuracy in detecting congenital heart diseases, given that the fetal heart assessment can be completed in the absence of the patient (offline) and be discussed by different examiners. Additionally, data volumes can be sent for analysis in reference centers via internet links. Spatiotemporal image correlation also enables direct measurement of heart structures in rendering mode, such as the interventricular septum and the annulus of the atrioventricular valves. Furthermore, it enables assessment of cardiac function when used in association with the virtual organ computer-aided analysis software, thus making it possible to calculate the total systolic function, ejection fraction, and cardiac output.

“…From the STIC acquisition, three‐dimensional voxels were created that had an X, Y, and Z component, resulting in three simultaneously displayed images referred to as the A, B, and C planes (Figure ). Following the first publication describing the STIC technique, numerous studies have been reported describing the use of this technique for evaluation of fetal cardiovascular structures and function …”

With the introduction of the electronic 4-dimensional and spatial-temporal image Correlation (e-STIC), it is now possible to obtain large volume datasets of the fetal heart that are virtually free of artifact. This allows the examiner to use a number of imaging modalities when recording the volumes that include two-dimensional real time, power and color Doppler, and B-flow images. Once the volumes are obtained, manipulation of the volume dataset allows the examiner to recreate views of the fetal heart that enable examination of cardiac anatomy. The value of this technology is that a volume of the fetal heart can be obtained, irrespective of the position of the fetus in utero, and manipulated to render images for interpretation and diagnosis. This article presents a summary of the various imaging techniques and provides clinical examples of its application used for prenatal diagnosis of congenital heart defects and abnormal cardiac function.
