Knowledge of the embryology of the normal heart is essential for understanding the development of congenital cardiopathies. However, learning embryology is not an easy matter because it requires understanding the intricacy and evolution of many complex structures and functions. Classically, this evolution is usually described in textbooks by means of drawings and sketches. With these techniques, however it is difficult to imagine the spatial and temporal links. Recent advances in computer graphics have brought about ways to illustrate these dimensions. We developed a 3-D animation of the full embryogenetic process of the normal heart.
