Blocked arteries are often a result of coronary heart disease where plaque is suck in the arteries and clogs them, according to WebMD. When not properly treated, the person may experience a stroke or heart attack, which can often be lethal. The stents are inserted during a minimally invasive surgery that will open up the arteries. The surgery, though minimally invasive, does carry risks such as blood clots, as stated by the National Heart, Lung and Blood Institute.
