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.
Your body isn't cut open except for a very small incision in the skin over a blood vessel in the leg, arm or wrist through which a small, thin tube (catheter) is threaded and the procedure performed. Angioplasty can take up to several hours, depending on the difficulty and number of blockages and whether any complications arise. Angioplasty is performed by a heart specialist (cardiologist) and a team of specialized cardiovascular nurses and technicians in a special operating room called a cardiac catheterization laboratory.
