Developing an accurate and detailed 3-dimensional (3D) mental model of cardiac anatomy is critical for electrophysiology (EP) trainees. Due to its immersive nature, virtual reality (VR) may provide a better learning environment than traditional teaching methods for assimilating 3D cardiac anatomy. The purpose of this pilot study was to evaluate the technical feasibility of an interactive, remote VR-based method for teaching cardiac anatomy to novice EP trainees. We created a shared, remote VR environment that allows the shared viewing of high-resolution 3D cardiac models. Eighteen trainees accepted for pediatric and adult EP fellowships were recruited. We performed a cohort study comparing the traditional teaching methods with the VR learning environment. Participants completed a demographic questionnaire and a satisfaction survey. The adult EP trainees were given a multiple-choice pre-and post-test exam to assess their anatomical knowledge. Both the adult and pediatric EP trainee cohorts rated the VR experience positively and preferred the VR environment to the more traditional teaching method. All the participants expressed interest in incorporating the VR learning environment into the EP fellowship curriculum. The usability of the system was relatively low, with approximately one-third of participants rating the system as hard to use. The impact of the VR session on exam performance was mixed among the adult cohort. We demonstrated the feasibility of gathering geographically dispersed EP fellows in training with a shared VR-based environment to teach cardiac anatomy. Although we were not able to demonstrate a learning benefit over the traditional lecture format in the adult cohort, the training environment was favorably received by all the participants.

Introduction Echocardiography is essential for diagnosing and assessing the severity of perioperative structural and functional heart disease. Yet, educational opportunities to better understand echocardiography‐based cardiac anatomy remain limited by the two‐dimensional display, lack of anatomic details, variability of heart models, and costs and global access of training. Methods We performed micro computed tomography of human heart specimens not suitable for orthotopic transplantation. We created high‐resolution computational 3D models of different human hearts, sliced them in the different recommended American Society of Echocardiography views, and 3D printed them using different materials. Results We scanned, 3D modeled, and 3D printed a variety of human hearts both healthy and diseased. We have made the models available in the cardiac operating rooms and routinely use them for teaching anesthesia residents and cardiothoracic anesthesia fellows about basic and advanced echocardiographic views, cardiopulmonary bypass cannulation strategies, and valvular pathology and planned interventions. Conclusion We have generated a library of 3D printed hearts to display the recommended echocardiographic views as a unique educational tool designed to safely accelerate the understanding of absolute and relative human cardiac anatomy and pathology, especially related to gaining advanced appreciation of clinically employed perioperative echocardiography.
