Definition
By Mayo Clinic staffCoronary angioplasty (AN-jee-o-plas-tee), also called percutaneous coronary intervention (PCI), is a procedure used to open clogged heart arteries. Angioplasty involves temporarily inserting and blowing up a tiny balloon where your artery is clogged to help widen the artery.
Angioplasty is often combined with the permanent placement of a small wire mesh tube called a stent to help prop the artery open and decrease the chance of it 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 some of the symptoms of blocked 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.
