Reaching competency in congenital heart surgery (CHS) requires lengthy and rigorous training. Due to patient safety, time limitations, and procedural complexity, the intraoperative setting is not ideal for technical practice. Surgical simulation using synthetic, biological, or virtual models is an increasingly valuable educational tool for technical training and assessment. In particular, three-dimensional (3D) models are especially favorable in CHS education for its high-fidelity demonstration of congenital heart defects. In countries where there is a deficit of local cardiac surgical expertise, simple and inexpensive innovation, such as expanding hands-on technical training programs involving 3D-models and hybrid teaching, may partially address the lack of CHS training opportunities and the consequent unmet need for surgical management of pediatric heart disease.
