Congenital heart defects can be difficult to visualize and explain. Heartpedia, created by Cincinnati Children's Hospital, allows you to interact with 3D models of pediatric heart anomalies and defects. Healthcare providers may use these anatomically-correct models as visual learning tools to help educate patients and families on specific defects and repairs. Heartpedia may also be helpful to patients and families who want to learn more on their own or to share the details of a defect with concerned friends and family. Cincinnati Children’s believes that supplying the right information and tools ultimately results in the highest level of care and the best outcomes.
