Introduction: Cardiac magnetic resonance imaging (CMR) is vital, but claustrophobia affects 10% of patients. The metaverse, an immersive virtual and augmented reality environment, has healthcare potential. We present a metaverse-based CMR simulation for claustrophobic patients. Methods: Three cardiomyopathy patients, initially CMR-refusing due to claustrophobia, received training via a virtual reality headset in a metaverse-based virtual hospital. Training efficacy was assessed through questionnaires and anxiety scales. Results: The patients successfully completed metaverse-based training, adapting to the CMR simulation. On CMR day, all entered the machine without issues and with reduced anxiety. Patients found the training useful, suggesting platform familiarization. Discussion: Our study demonstrates the metaverse's potential in alleviating CMR-related claustrophobia. The immersive nature enhances patient preparation, although usability improvements are needed. Further research should compare this approach with alternatives.

Cardiac magnetic resonance imaging (CMR) is a vital tool for diagnosing heart problems, but some patients cannot undergo it due to claustrophobia. To address this, researchers are exploring new methods like hypnosis and simulations. One emerging technology, the metaverse, a 3D virtual reality (VR) environment, is being tested in healthcare. This study created a metaverse-based simulation to help claustrophobic patients prepare for CMR. Three patients with heart issues were given VR headsets to access a virtual hospital in the metaverse. Inside, they were trained for CMR step by step, experiencing the process and sounds realistically. Training was done 1 week, 3 days, and 1 day before the real CMR. Anxiety levels were measured. All patients completed the virtual training without issues. During the first simulations, some could not complete entering the virtual CMR machine due to anxiety. However, by the final simulation, all succeeded. On CMR day, all completed the scan without problems, and their anxiety levels decreased significantly from the initial training. Patients found the training helpful, but the platform's usability needed improvement. The study demonstrates that metaverse-based simulations can help patients overcome claustrophobia to successfully undergo CMR. This technology holds promise for simulating medical situations, easing patient fears, and improving preparation. However, further work is needed to make it user-friendly and accessible without assistance. This study encourages more research to assess the usefulness of the metaverse for broader patient groups, comparing it with other methods like hypnosis or sedation.
