Coronary Angioplasty, also called Percutaneous Coronary Intervention, is a procedure used to open clogged arteries supplying the heart. These arteries are called the coronary arteries. Angioplasty involves temporarily inserting and inflating a tiny balloon where your artery is clogged, to help widen the artery.
Angioplasty is generally combined with the stable placement of a small wire mesh tube called a stent to help prop the artery open and reduce its chance of narrowing again. Some stents are coated with medication to help keep your artery open (drug-eluting stents), while others are not (bare-metal stents).
Angioplasty can improve symptoms caused by of blocked heart arteries, such as chest pain and shortness of breath. Angioplasty can also be used during a heart attack to quickly open a blocked artery and reduce the amount of damage to your heart.
