“…Therefore, a three-dimensional approach is essential [ 9 , 33 ] to share the complex anatomy and discuss the optimal therapeutic approach [ 10 , 11 , 34 ]. The more complicated the features of the involved heart, the more precise three-dimensional recognition is required, which provides a huge arena for stereograms in this field [ 16 ]. Cardiac magnetic resonance imaging is the gold standard for functional and morphological cardiac assessments [ 35 , 36 , 37 ].…”

“…To the best of our knowledge, this simple method to obtain real depth perception was applied to the field of cardiology in 1908 by DeWitt, who showed a model of the cardiac conduction system [ 13 ]. The usefulness of this conventional method in the field of cardiology has recently regained focus [ 4 , 14 , 15 , 16 ]. The convenience of this technique, without the use of expensive equipment, could vitalize the three-dimensional images currently demonstrated on a two-dimensional surface.…”

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.

Background: The authors had earlier studied the utility of stereoscopic projection of neuroanatomic three-dimensional models through AnaVu (a low resource stereoscopic projection system) on medical students. The tool was developed by collaboration between anatomy teachers, radiologists, and visualization experts. Although the preliminary results indicated advantages in learning, the perspective of the anatomy teachers, the end users of the tool, was not known and hence this study. Methodology: A cross-sectional study of the observational nature was conducted where Faculty of South Kerala was informed that they will be given an opportunity for a hands-on experience to use AnaVu. A 15-min session was given to each teacher. Their feedbacks were collected using a prevalidated questionnaire tool and open comments were also collected. Analysis was done using the software SPSS and RQDA. Results: Thirteen faculty members participated in the study. Quantitative analysis showed that teachers were able to teach (4 ± 0.57), likely to use it for teaching if made available (4 ± 0.71), found it easy to use (3.31 ± 0.48), and realistic to anatomy (3.62 ± 0.87). Qualitative analysis showed general appreciation and advantage in teaching spatial anatomy. Faculty also pointed limitations such as lack of interaction with students, eye strain, and need for training to use the tool. Conclusion: The study points to the utility of AnaVu, a low resource tool in teaching spatial anatomy. The study also dealt with the concerns that need to be addressed during the scaling of such a tool for utility in the Indian Anatomy education scenario.
