“…The lack of familiarity with the stereoscopic system could also explain the longer time required to analyze the cases. A longer processing time was also revealed by the results of the examination of 3D echocardiography [ 7 ]. Even so, the aneurysms were diagnosed equally quickly on both imaging systems and the residents were able to identify both aneurysm cases faster using the stereoscopic system compared to the consultants.…”

“…Due to depth perception created by the projection of a slightly different image to each eye, stereoscopic displays allow a more accurate visualization compared to three-dimensional (3D) images on two-dimensional (2D) displays [ 6 ]. In this regard, Harake et al demonstrated that interactive stereoscopic visualization of three-dimensional echocardiography was preferred over conventional display by cardiologists, advanced cardiac trainees, and surgeons in viewing both simple and complex congenital cardiac lesions [ 7 ]. Surgical disciplines, like neurosurgery, orthopedics, or visceral surgery, are particularly interested in new ways to visualize complex anatomical relations during surgical planning [ 1 , 4 , 5 ].…”

Stereoscopic imaging has increasingly been used in anatomical teaching and neurosurgery. The aim of our study was to analyze the potential utility of stereoscopic imaging as a tool for memorizing neurosurgical patient cases compared to conventional monoscopic visualization. A total of 16 residents and 6 consultants from the Department of Neurosurgery at Charité – Universitätsmedizin Berlin were recruited for the study. They were divided into two equally experienced groups. A comparative analysis of both imaging modalities was conducted in which four different cases were assessed by the participants. Following the image assessment, two questionnaires, one analyzing the subjective judgment using the 5-point Likert Scale and the other assessing the memorization and anatomical accuracy, were completed by all participants. Both groups had the same median year of experience (5) and stereoacuity (≤ 75 s of arc). The analysis of the first questionnaire demonstrated significant subjective superiority of the monoscopic imaging in evaluation of the pathology (median: monoscopic: 4; stereoscopic: 3; p = 0.020) and in handling of the system (median: monoscopic: 5; stereoscopic: 2; p < 0.001). The second questionnaire showed that the anatomical characterization of the pathologies was comparable between both visualization methods. Most participants rated the stereoscopic visualization as worse compared to the monoscopic visualization, probably due to a lack of familiarity with the newer technique. Stereoscopic imaging, however, was not objectively inferior to traditional monoscopic imaging for anatomical comprehension. Further methodological developments and incorporation in routine clinical workflows will most likely enhance the usability and acceptance of stereoscopic visualization.

“…We randomly selected 10 sonographers (the average age is 35.6 ± 10.73 years) as the echocardiographer group, eight doctors (40 ± 8.9 years) who specialize in cardiac intervention or thoracotomy surgery as the cardiac surgeon group (no limitation on working years, including doctors who have worked for 1–25 years, the overall average age is 37.6 ± 9.7 years), six cardiologists specializing in CHD interventional techniques (unlimited years of experience, including worked for 1–30 years, mean age 32.5 ± 11.3 years), and 20 patients with CHD (or a parent of a child under 14 years) who underwent the novel 3D echocardiographic examinations to fill out a short questionnaire evaluating their experience, they were all provided score [using Likert score system ( Harake et al, 2020 )] the elements after viewing/manipulate the new series of 3D images/videos by comparing with the traditional 3D for 30 cases randomly selected from the database ( Table 1 ). None of the participants had prior experience with the TrueVue series of technologies.…”

Aims: This study explored the advantages and limitations of novel series of three-dimensional (3D) echocardiographic techniques and summarized their application methods for congenital heart diseases (CHDs).Method and result: Two-dimensional (2D), traditional 3D echocardiography, and TrueVue plus light and/or Glass novel 3D technologies were performed on 62 patients with CHD, and a clinical survey was designed to judge whether the novel 3D images were more helpful for understanding the cardiac condition and guide treatment than traditional 3D images. TrueVue increased the visual resolution and simulated the true texture of cardiac tissue, significantly improving the display ability of abnormal anatomical structures in CHDs. TrueVue Glass displayed the blood channel and the internal structure of cardiac cavity more intuitively, indicating a new observation aspect not shown by conventional echocardiography. The clinical survey results showed that the new 3D imaging methods effectively increased the diagnostic confidence of echocardiographers, enabled surgeons to better understand the details of lesions, promoted efficient communication, and improved the confidence of both doctors and patients in treatment.Conclusion: The combined application of TrueVue, TrueVue Light, and TrueVue Glass more closely simulated real anatomical features, showed more comprehensive and subtle blood flow in the lumen, not only increased the visual effect but also provided more useful diagnostic information, improved the accuracy of evaluation and treatment of CHD when compared to traditional imaging techniques, indicating that this combined application has significant clinical value.

“…However, owing to their two-dimensional display, these three-dimensional images cannot provide real depth perception. Equipment that overcomes this limitation includes three-dimensional printing, three-dimensional projectors/monitors, and virtual reality applications, which enhance real three-dimensional visualization with depth perception [ 6 , 7 , 8 , 9 , 10 , 11 ]. However, these new methodologies have limitations in terms of user-friendliness, cost performance, and clinical relevance, which prevent them from being widely applied in clinical practice.…”

Innovations in invasive cardiovascular diagnostics and therapeutics, not only limited to transcatheter approaches but also involving surgical approaches, are based on a precise appreciation of the three-dimensional living heart anatomy. Rapid advancements in three-dimensional cardiovascular imaging technologies in the 21st century have supported such innovations through the periprocedural assessment of the clinical anatomy of the living heart. However, even if high-resolution volume-rendered images are reconstructed, they cannot provide appropriate depth perception when displayed and shared on a two-dimensional display, which is widely used in clinical settings. Currently, images reconstructed from clinical datasets can visualize fine details of the cardiovascular anatomy. Therefore, this is an optimal time for cardiologists and cardiac surgeons to revisit the classic technology, stereopsis, and obtain bonus information from carefully reconstructed clinical images. Using anaglyphs or cross/uncross-fusion of paired images, striking depth perception can be readily obtained without the need for expensive equipment. This conventional technique, when applied to high-resolution volume-rendered images, may help in obtaining appropriate diagnostics, choosing optimal therapeutics, securing procedural success, and preventing complications. Furthermore, it can be used for anatomical education. In this review, we demonstrate multiple stereoscopic images reconstructed from cardiac computed tomographic datasets and discuss their clinical and educational implications.
