This 3d medical animation shows a heart attack resulting from atherosclerosis, which is inflammation of the artery. It was designed to be an immersive experience to hold the viewer’s interest in this complex, slow-developing process. Every shot was conceptualized as a visual effect to evoke the sensation of a journey within a dynamic and diverse environment. Beginning with the probable cause, which is damage to the endothelial wall, the story progresses in detail through the stages of atherosclerosis concluding with the resulting damage to the heart.
