Angioplasty (or Balloon angioplasty) is an endovascular procedure to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis. An empty, collapsed balloon, known as a balloon catheter, is passed over a wire into the narrowed locations and then inflated to a fixed size.
This is a room fitted with X-ray equipment to allow the doctor to monitor the procedure on a screen. A coronary angioplasty usually takes between 30 minutes and two hours, although it can take longer. You'll be asked to lie on your back on an X-ray table. You'll be linked up to a heart monitor and given a local anaesthetic to numb your skin.
