医学动画：冠脉造影支架术
http://player.youku.com/player.php/sid/XMzYwNjQ1OTQw==.htmlThis 3D heart animation shows a coronary artery angioplasty surgery, also called a percutaneous coronary intervention, or PCI, to correct a blocked artery in the heart. 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 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.
