Angioplasty is the commonly used term for coronary angioplasty. The more technical terms used for the same procedure are percutaneous coronary intervention (PCI) and percutaneous transluminal coronary angioplasty (PTCA). Angioplasty is a procedure to open blocked arteries in your heart by inserting and inflating a tiny balloon. Most patients who undergo angioplasty also get a ?stenting? done at the same time. Stents are coiled metal meshes that hold the arteries open and reduce the chances of re-narrowing (restenosis). Stents coated with drugs to decrease clotting or narrowing at the site are called drug eluting stents (DES). Uncoated stents are called bare metal stents.
