Heart stent procedure videos are available to watch online on various websites such as WebMD and Mayo Clinic. The Visual MD and the National Heart, Lung, and Blood Institute also show videos where a stent procedure is performed along with additional information regarding stents.
A stent is a small tube made from metal mesh or fabric, that is used to treat narrow or weak arteries, states the National Heart, Lung, and Blood Institute. Fabric stents, also known as stent grafts, are usually used for larger arteries. Drug-eluting stents help to prevent arteries from becoming blocked again by slowly and continuously releasing a medicine into the artery, according to the National Heart, Lung, and Blood Institute.
