Coronary angioplasty is a procedure used to widen blocked or narrowed coronary arteries (the blood vessels supplying the heart).
The procedure includes temporarily inserting a tiny balloon where your artery is clogged to stretch open it and is often combined with the permanent replacement of a small wire mesh tube, called a stent. The stent is left in place permanently to restore the blood supply to the heart and decrease its chance of narrowing again.
When is it done?
Angioplasty is used to treat heart disease known as atherosclerosis (buildup of fatty plaques at in the arteries supplying the heart).
Your doctor might suggest angioplasty as a treatment options when the medication is ineffective to improve your heart health, if you have a worsening chest pain (angina pain), or if you have a heart attack.
