Computer-Based Simulation for Pediatric Cardiovascular Disease Management: A Policy Brief

Background

Cardiovascular diseases are significant global health concerns, particularly in children, and encompass a broad spectrum of conditions from congenital heart defects to acquired heart diseases.^1,2 Despite medical advancements, treating pediatric CVDs remains complex, often requiring intricate surgeries, medications, or catheter-based procedures. ³ CHDs affect a considerable number of infants annually and complicate surgical planning due to anatomical intricacies.^4-7 Accurate diagnosis and preoperative planning heavily rely on precise depictions of the heart’s anatomy and function, yet traditional imaging methods such as 2-dimensional echocardiography, have limitations in portraying the intricate 3-dimensional dynamics of the heart.^4,5,8

In recent years, computer-based simulation (CBS) technologies have emerged as promising tools in pediatric cardiovascular care, offering innovative solutions to longstanding challenges.^9-12 These technologies, including Virtual Reality (VR), Augmented Reality (AR), Mixed Reality (MR), and 3D modeling, hold immense potential to revolutionize medical education, surgical planning, and procedural training. ⁶ By providing realistic virtual models of the heart, CBS offers a platform for comprehensive analysis, enhancing the understanding of complex cardiac pathologies and interventions.^11,13-20

Recent advancements in Extended Reality (XR), particularly in VR headsets and graphics cards, have significantly enhanced user experience, making VR a prime candidate for surgical planning and diagnostics due to its immersive nature. ²¹ AR and MR are attractive for real-time procedural guidance as they allow surgeons to maintain real-world awareness.^21,22 However, there are several challenges including a limited visual field, resolution limitations, and the need for a regulatory approval. Clinical studies on XR’s impact on procedural outcomes in pediatric structural heart disease are scarce and varied due to the complexities of patient populations. However, their results suggest the positive outcomes of using the technology which includes improving operator confidence, reducing procedural times, and enhancing anatomical understanding.^21,22

Healthcare providers, policymakers, and medical instructors can simulate real-world scenarios and gain practical insights into how these technologies can revolutionize diagnostic accuracy, surgical planning, and medical training in this critical field.^23,24

Pediatric CVDs management presents unique challenges due to its complexity and the limitations of conventional imaging methods. Fortunately, CBS technologies, including VR, AR, and 3D modeling, are emerging as powerful tools to improve patient care in this critical area. This policy brief explores the potential of CBS in pediatric cardiology, highlighting its impact on diagnosis, surgical planning, procedures, and training. By understanding the benefits of CBS, policymakers can create an environment that fosters its widespread adoption and integration into pediatric cardiac care practices for better health outcomes.

Policy Background

The FDA highlights how AR and VR are transforming healthcare with innovative diagnostic and treatment methods. AR and VR enhance pediatric diagnostics, pain management, mental health treatment, neurological rehabilitation, and surgical planning. They also improve ophthalmic diagnostics and expand telemedicine, making healthcare more accessible. Despite their benefits, AR/VR technologies pose risks such as cyber-sickness, physical strain, cybersecurity issues, potential distractions during procedures, and unknown side effects, particularly in vulnerable populations like children. As a result, the FDA regulates AR/VR medical devices and provides a periodically updated list of approved devices, ensuring careful management to mitigate these risks. ²⁵

In another policy brief, the European Institute for Asian Studies spotlights the growing role of digital tools in enhancing clinical outcomes, with efforts focused on digital infrastructure and emerging technologies. The policy brief indicated that adopting computer-based simulations requires policy measures for standardized protocols, data interoperability, and specialized training. It also stresses the importance of secure integration to protect patient data. Prioritizing these technologies could improve decision-making and care quality for patient’s conditions while aligning with broader EU digital health strategies. ²⁶
