What Is an Angioplasty Procedure?
An angioplasty is a procedure that can be used to open blocked arteries in the heart (known as coronary arteries) and improve blood and oxygen flow to your heart without open heart surgery. It is common for an expandable device, called a stent, to be inserted into your blocked artery after angioplasty. Stents can help the artery remain open for a longer time.
