If a coronary artery is narrowed by a buildup of plaque, it can reduce blood flow to the heart muscle. A stent is a small wire mesh tube that is placed in an artery to help keep it open, lessening your risk of having a heart attack. To open a narrowed artery and implant a stent, a surgeon may perform an angioplasty or a percutaneous coronary intervention (PCI).
