Coronary angioplasty, also called a percutaneous coronary intervention, is a procedure used to open blocked or narrowed heart arteries. The procedure improves blood flow to the heart muscle.
It involves temporarily inserting and inflating a tiny balloon where your artery is clogged to help widen the artery.
Angioplasty is often combined with the placement of a small wire mesh tube called a stent to help prop the artery open and decrease its chance of narrowing again. Some stents are coated with medication to help keep your artery open, while others are not.
This operation can improve symptoms of blocked arteries, such as chest pain and shortness of breath.
