Description: This 3D medical animation depicts a coronary angiography procedure. It begins by showing the buildup of plaque in an artery wall of the heart, blocking the flow of blood. Afterwards, the patient lies on a testing table while contrast dye is injected into the arteries of the heart, showing the location of the blockage. A guide wire is then moved through the lumen of the blocked blood vessel, followed by a balloon and stent mechanism. The balloon inflates, putting the metal stent in place, so that the lumen of the artery is open and the red blood cells can flow freely.
