Rehabilitation is an essential component of comprehensive care for children with congenital heart defects (CHD), aiming to enhance cardiovascular health, physical fitness, and overall quality of life. Affecting approximately 1% of live births globally, CHD remains one of the most prevalent congenital anomalies. Advances in medical and surgical interventions have significantly improved survival rates; however, ongoing rehabilitation is critical for managing residual symptoms, optimizing functional outcomes, and addressing psychosocial needs. Methodology: This randomized controlled trial (RCT) employs a mixed-methods approach to evaluate the effectiveness of 3D glasses in pediatric cardiac rehabilitation, integrating quantitative data with qualitative insights from healthcare providers, parents, and children. A total of 98 participants, aged 5–18 years and diagnosed with congenital heart defects (CHD) under ICD codes Q20–28, were recruited from pediatric cardiology and rehabilitation centers and divided into experimental and control groups. Results: A total of 98 children with congenital heart defects participated in the study. The demographic distribution included 45.9% girls and 54.1% boys. The participants were divided into three age groups: 5-9 years, 10-14 years, and 15-18 years. The majority of children (69.4%) were in the 5-9 years age group, followed by 25.5% in the 10-14 years group, and 5.1% in the 15-18 years group. The mean values (m) for each category showed a relatively balanced distribution by gender, with boys and girls both having a mean of 5.0. Age distribution means were as follows: 4.6 for the 5-9 years group, 4.4 for the 10-14 years group, and 2.2 for the 15-18 years group. This demographic overview indicates a predominance of younger children (5-9 years) in the study, reflecting a potentially higher demand for innovative rehabilitation methods, such as 3D glasses, in this age group. In conclusion, integrating 3D glasses into rehabilitation for children with congenital heart defects offers a unique and engaging way to enhance both physical and psychological recovery. The immersive and interactive virtual experiences help increase motivation, reduce anxiety, and support cardiovascular health in a child-friendly manner. This innovative approach shows great potential for improving rehabilitation outcomes and overall well-being in pediatric cardiac patients.
