Angioplasty is a procedure where a tiny balloon is used to restore blood flow to the heart by
reopening arteries closed or narrowed down by 'plaques'.
During an angioplasty procedure, the cardiologist punctures a blood vessel, often in the groin, and inserts a small,
thin tube known as a catheter, which is then led to the heart.
Attached to the end of the catheter is a balloon, which is inflated to widen the artery.
A permanent stent is often put in place to keep the artery open before the balloon catheter is removed.
