“…AR is assuming a fundamental and emerging role also for what concerns surgical training and medical education [79][80][81][82][83]. Its introduction results in providing students with a better anatomic conceptualization and allows surgical simulations to improve their performances [84].…”

Augmented reality (AR) is an innovative system that enhances the real world by superimposing virtual objects on reality. The aim of this study was to analyze the application of AR in medicine and which of its technical solutions are the most used. We carried out a scoping review of the articles published between 2019 and February 2022. The initial search yielded a total of 2649 articles. After applying filters, removing duplicates and screening, we included 34 articles in our analysis. The analysis of the articles highlighted that AR has been traditionally and mainly used in orthopedics in addition to maxillofacial surgery and oncology. Regarding the display application in AR, the Microsoft HoloLens Optical Viewer is the most used method. Moreover, for the tracking and registration phases, the marker-based method with a rigid registration remains the most used system. Overall, the results of this study suggested that AR is an innovative technology with numerous advantages, finding applications in several new surgery domains. Considering the available data, it is not possible to clearly identify all the fields of application and the best technologies regarding AR.

“…In order to overcome this possible problem, new technologies have emerged, where the virtual 3D model is projected the virtual and/or mixed reality space [38,39] and the spectator wearing special glasses can interact with them with/out haptic feedback [40][41][42] (Figure 1B). These developing techniques are in the process of maturation and in finding their niche in the clinical armamentarium [43][44][45][46]; however, the need for 3D-printed models remains, as they readily exist in the physical reality and they accurately demonstrate rather complex morphologies [47], which can be printed with the physical properties of native tissues [48].…”

“…As another direction, rapid development in holographic technology carries potentials for 3D modeling. Holograms offer quicker production time and low budget solution compared to 3D printing [45,46]. Applications allow free maneuverability, free magnification, the possibility of virtual tours inside the cardiac chambers and segments as a shared 3D team experience.…”

“…Superimposed holograms on intraoperative scenarios are currently introduced as surgical decision making and adjuvant tool in several surgical disciplines [71]. Provided that computational strength increases in future versions, higherresolution cardiac-cycle models could be imported into the virtual/mixed reality from dynamic imaging sources, e.g., 3D echocardiography, structure and function will conjoin [45]. The application will also solve the problem of the currently suboptimal representation of the cardiac valves [45].…”

Three-Dimensional Virtual and Printed Prototypes in Complex Congenital and Pediatric Cardiac Surgery—A Multidisciplinary Team-Learning Experience

Three-dimensional (3D) virtual modeling and printing advances individualized medicine and surgery. In congenital cardiac surgery, 3D virtual models and printed prototypes offer advantages of better understanding of complex anatomy, hands-on preoperative surgical planning and emulation, and improved communication within the multidisciplinary team and to patients. We report our single center team-learning experience about the realization and validation of possible clinical benefits of 3D-printed models in surgical planning of complex congenital cardiac surgery. CT-angiography raw data were segmented into 3D-virtual models of the heart-great vessels. Prototypes were 3D-printed as rigid “blood-volume” and flexible “hollow”. The accuracy of the models was evaluated intraoperatively. Production steps were realized in the framework of a clinical/research partnership. We produced 3D prototypes of the heart-great vessels for 15 case scenarios (nine males, median age: 11 months) undergoing complex intracardiac repairs. Parity between 3D models and intraoperative structures was within 1 mm range. Models refined diagnostics in 13/15, provided new anatomic information in 9/15. As a team-learning experience, all complex staged redo-operations (13/15; Aristotle-score mean: 10.64 ± 1.95) were rehearsed on the 3D models preoperatively. 3D-printed prototypes significantly contributed to an improved/alternative operative plan on the surgical approach, modification of intracardiac repair in 13/15. No operative morbidity/mortality occurred. Our clinical/research partnership provided coverage for the extra time/labor and material/machinery not financed by insurance. 3D-printed models provided a team-learning experience and contributed to the safety of complex congenital cardiac surgeries. A clinical/research partnership may open avenues for bioprinting of patient-specific implants.

“…Future work should replicate this study in other augmented and virtual reality environments. For instance, there is new and promising work in the use of holograms for teaching and learning across the lifespan (e.g., Moro, Phelps, Jones, & Stromberga, 2020). Otherwise, digital settings like Minecraft.edu are increasingly hosting live lessons in K12 and higher education (e.g., Callaghan, 2016), suggesting a new front to analyze.…”

Research has provided evidence of the value of producing multiple representations of content for learners (e.g., verbal, visual, etc.). However, much of the research has acknowledged changes in visual technologies while not recognizing or utilizing related audio innovations. For instance, teacher education students who were once taught through two-dimensional video are now being presented with interactive, three-dimensional content (e.g., simulations or 360 video). Users in old and new formats, however, still typically receive monophonic sound. A limited number of research studies exist that have examined the impact of combining three-dimensional sound to match three-dimensional video in learning environments. The purpose of this study was to respond to this gap by comparing the outcomes of watching 360 video with either monophonic or ambisonic audio. Results provided evidence that ambisonic audio increased perceived presence for those familiar with the content being taught, led to differentiation in what ambisonic viewers noticed compared to monophonic groups, and improved participant focus in watching the 360 video. Implications for the development and implementation into virtual worlds are discussed.
