Angioplasty, also known as balloon angioplasty and percutaneous transluminal angioplasty (PTA), is a minimally invasive, endovascular procedure to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis.
Performing an angioplasty involves a doctor inflating a thin balloon in the artery to widen it at the blockage, leaving a stent in place to prop the blood vessel open. It can be lifesaving when performed within hours of a heart attack.
