Also known as:
Percutaneous coronary intervention, PCI
Angioplasty and related techniques are known as percutaneous coronary intervention (PCI). Angioplasty is a procedure in which a narrowed section of the coronary artery is widened. Angioplasty is less invasive and has a shorter recovery time than bypass surgery, which is also done to increase blood flow to the heart muscle but requires open-heart surgery. Most of the time stents are placed during angioplasty. An angioplasty is done using a thin, soft tube called a catheter. A doctor inserts the catheter into a blood vessel in the groin or wrist. The doctor carefully guides the catheter through blood vessels until it reaches the blocked portion of the coronary artery.
