Angioplasty is a procedure that is performed by cardiologists to restore blood flow through the arteries. Doctors perform angioplasty to reduce the chest pain caused by reduced blood flow to the heart and minimize the damage to heart muscle from a heart attack.
In this procedure, doctor threads a thin tube through a blood vessel in the arm or groin up to the involved site in the artery. The tube has a tiny balloon attached on the end. When the tube reaches the place, the doctor inflates the balloon to push the plaque outward against the wall of the artery. This widens the artery and restores the blood flow for the patient.
