Abstract

Funding Acknowledgements La Fondation Dassault Systèmes, British Heart Foundation Background Virtual reality (VR) provides a unique possibility to interact with three-dimensional objects. Still in its infancy, the integration of VR with advanced cardiovascular imaging technology allows users to handle patient-specific cardiac models. Purpose The purpose of this study was to evaluate the potential role of VR in teaching cardiac morphology of congenital heart diseases to healthcare professionals. Methods From October 2018 to April 2019, a VR application was developed in-house and incorporated within the Cardiac Morphology courses run monthly at our centre. The VR software included patient-specific 3D models which were reconstructed from 3D imaging datasets (micro-CT, CT, CMR or 3D echo data). The most important cardiac structures were labelled to allow easier identification of anatomical features (Figure 1). Each participant had the possibility to evaluate 6 different patient specific models including: a foetal normal heart, a foetal Transposition of the Great Arteries, a foetal Atrioventricular septal defect, a four-month-old Tetralogy of Fallot, a four-month-old Double Outlet Right Ventricle with uncommitted ventricular septal defect and a one-year-old Patent Ductus Arteriosus. All the attendees could evaluate the models individually for 5 to 15 minutes. A short survey with six questions was administered at the end of the session. The survey included sections asking for professional background information, prior VR experience and feedback on the VR experience which was assessed with a 5 points Likert-type scale (from 1 to 5). Results The VR session was attended by 20 delegates with mixed professional backgrounds including cardiac surgeons, cardiologists, cardiac anaesthesiologists, paediatricians, pathologists and medical students. Only 2 out of 20 had tried a virtual reality application before, although neither of those prior VR experiences had a medical focus. The VR application was considered ‘’extremely helpful’’ (5/5) in understanding the anatomy by 44% of participants, and ‘’very helpful’’(4/5) by another 44%. The methods of interaction (e.g. grabbing objects, using a cutting tool) were considered "extremely intuitive’’ (5/5) by 72% of attendees, and "very intuitive"(4/5) by 27%. In 94% of the cases, the attendees responded to be "very willing"(4/5) or "extremely willing"(5/5) to implement a VR setup at their own institutions for the purpose of evaluating cardiac anatomies. Conclusion The use of the VR station in cardiac morphology courses was very well received by the attendees, as it is frequently considered easy to use and very helpful in aiding the understanding of congenital heart diseases. The survey highlighted a great potential for implementing this tool in educational programmes. Abstract P369 Figure 1

Background: Virtual reality (VR) provides a unique possibility to interact with three-dimensional objects. Still in its infancy, the integration of
VR with advanced cardiovascular imaging technology allows users to handle patient-specific cardiac models.
Purpose: The purpose of this study was to evaluate the potential role of VR in teaching cardiac morphology of congenital heart diseases to
healthcare professionals.
Methods: From October 2018 to April 2019, a VR application was developed in-house and incorporated within the Cardiac Morphology cour-
ses run monthly at our centre. The VR software included patient-specific 3D models which were reconstructed from 3D imaging datasets
(micro-CT, CT, CMR or 3D echo data). The most important cardiac structures were labelled to allow easier identification of anatomical fea-
tures (Figure 1). Each participant had the possibility to evaluate 6 different patient specific models including: a foetal normal heart, a foetal
Transposition of the Great Arteries, a foetal Atrioventricular septal defect, a four-month-old Tetralogy of Fallot, a four-month-old Double Outlet
Right Ventricle with uncommitted ventricular septal defect and a one-year-old Patent Ductus Arteriosus. All the attendees could evaluate the
models individually for 5 to 15 minutes. A short survey with six questions was administered at the end of the session. The survey included
sections asking for professional background information, prior VR experience and feedback on the VR experience which was assessed with
a 5 points Likert-type scale (from 1 to 5).
Results: The VR session was attended by 20 delegates with mixed professional backgrounds including cardiac surgeons, cardiologists, car-
diac anaesthesiologists, paediatricians, pathologists and medical students. Only 2 out of 20 had tried a virtual reality application before, al-
though neither of those prior VR experiences had a medical focus. The VR application was considered ‘’extremely helpful’’ (5/5) in under-
standing the anatomy by 44% of participants, and ‘’very helpful’’(4/5) by another 44%. The methods of interaction (e.g. grabbing objects,
using a cutting tool) were considered "extremely intuitive’’ (5/5) by 72% of attendees, and "very intuitive"(4/5) by 27%. In 94% of the cases,
the attendees responded to be "very willing"(4/5) or "extremely willing"(5/5) to implement a VR setup at their own institutions for the purpose
of evaluating cardiac anatomies.
Conclusion: The use of the VR station in cardiac morphology courses was very well received by the attendees, as it is frequently consid-
ered easy to use and very helpful in aiding the understanding of congenital heart diseases. The survey highlighted a great potential for im-
plementing this tool in educational programmes.

Purpose of Review To provide an overview of the impact of virtual and augmented reality in contemporary cardiovascular medical practice. Recent Findings The utilization of virtual and augmented reality has emerged as an innovative technique in various cardiovascular subspecialties, including interventional adult, pediatric, and adult congenital as well as structural heart disease and heart failure. In particular, electrophysiology has proven valuable for both diagnostic and therapeutic procedures. The incorporation of 3D reconstruction modeling has significantly enhanced our understanding of patient anatomy and morphology, thereby improving diagnostic accuracy and patient outcomes. Summary The interactive modeling of cardiac structure and function within the virtual realm plays a pivotal role in comprehending complex congenital, structural, and coronary pathology. This, in turn, contributes to safer interventions and surgical procedures. Noteworthy applications include septal defect device closure, transcatheter valvular interventions, and left atrial occlusion device implantation. The implementation of virtual reality has been shown to yield cost savings in healthcare, reduce procedure time, minimize radiation exposure, lower intravenous contrast usage, and decrease the extent of anesthesia required. These benefits collectively result in a more efficient and effective approach to patient care.

Justification. Technological innovations have revolutionized medical practice, especially in the field of cardiac surgery, where the complex nature of interventions requires precision and foresight. The use of virtual (VR) and augmented reality (AR) in this field opens up huge prospects for improving preoperative planning, improving the quality of medical education and, ultimately, improving patient treatment outcomes. Aim. to analyze the literature on the role of VR/AR in modern cardiology, to discuss the current role and future directions in this field. Material and methods. As a result of the search, 3,858 publications were extracted from PubMed/MEDLINE, 69 publications from eLibrary and 1,115 publications found using Google Scholar. The search queries included the following keywords and their combinations: virtual reality, augmented reality, cardiology, cardiac surgery, virtual reality, augmented reality, cardiology, cardiac surgery. Search time interval: since the foundation of the corresponding database until May 2024. Results. Modern cardiological care includes increasingly complex procedures that require a high level of expertise. VR is becoming a powerful tool for both pre-procedural planning and educational events. VR opens up new opportunities for education and training of specialists in the field of cardiology. With its help, you can create realistic simulations of various situations that doctors may encounter in their work. This allows students to gain hands-on experience without risking real patients. Conclusion. The integration of VR into cardiology practice has great potential, but for full integration it is necessary to solve a number of problems. It is necessary to develop standards for the safety and effectiveness of using VR for medical purposes. Additional research is also needed to assess the long-term health effects of VR use on patients.

Virtual Reality (VR) has applications in Cardiology to create enhancement, thereby improving the quality of associated planning, treatment and surgery. The need is to study different applications of this technology in the field of cardiology. We have studied research papers on Virtual reality and its applications in cardiology through a detailed bibliometric analysis. The study identified five significant steps for proper implementation of this technology in cardiology. Some challenges are to be undertaken by using this technology, and they can provide some benefits; thus, authors contemplate extensive research & development. This study also identifies ten major VR technology applications in cardiology and provided a brief description. This innovative technology helps a heart surgeon to perform complex heart surgery effectively. Thus, VR applications have the potential for improving decision-making, which helps save human life. VR plays a significant role in the development of a surgical procedure. This technology undertakes 3D heart model information in full-colour, which helps analyse the overall heart vane, blockage and blood flow. With the help of this digital technology, a surgeon can improve the accuracy of heart surgery, and he can simulate the surgery. A surgeon can undertake surgery in a virtual environment on a virtual patient. The unique purpose of this technology is to practice preoperatively on the specific circumstance. A cardiologist can also check the proper status of inner and outer heart wall layer. Thus, by using this 3D information, the surgeon can now interact with heart data/information without any physical touch. This technology opens a new opportunity to improve heart surgery and development in cardiovascular treatment to improve patient outcome.
