This 3D model of a heart with truncus arteriosus provides a detailed and accurate representation of this rare congenital heart defect. It illustrates the single large blood vessel (truncus arteriosus) arising from the heart, supplying blood to both the lungs and the body, along with an associated ventricular septal defect (VSD).

The model effectively demonstrates the mixing of oxygen-rich and oxygen-poor blood, highlighting its impact on circulation and oxygen delivery. Designed for educational and clinical purposes, it serves as an invaluable tool for medical professionals, educators, and students to study cardiac anatomy, understand the hemodynamic challenges of truncus arteriosus, and visualize surgical repair techniques.

Its realistic design enhances comprehension of this complex condition, making it ideal for teaching, training, and patient education.
