(LifeWire) - Definition: Procedure using a tiny balloon to restore blood flow to the heart by reopening arteries closed or narrowed by atheroaclerosis, or plaque buildup.
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.
Angioplasty is not considered surgery and does not usually require the patient to be under complete anesthesia. The desired result is a reduction in chest pain and breathing difficulties.
Also Known As: percutaneous coronary intervention (PCI), balloon angioplasty
