Percutaneous Coronary Intervention- Coronary Angioplasty

Percutaneous Coronary Intervention, commonly known as coronary or balloon angioplasty, is a procedure to widen blocked arteries and restore blood flow to the heart muscle. PCI is used in cases where plaque buildup inside the arteries, known as athersclerosis or "hardening of the arteries," causes a risk factor for heart attack. Coronary angiography, which uses a special dye visible on live X-Ray, is performed to locate the blocked artery. A balloon catheter expands the artery at the blockage, allowing blood to flow through the artery. A stent is often used to keep the artery open. A drug-eluting stent releases medication over time that will keep the blockage from reforming inside the stent.
