Percutaneous coronary angioplasty is a therapeutic procedure to open a narrowed or blocked artery which supply blood to the heart. Percutaneous coronary angioplasty is used when the buildup of plaque which blocks the flow of blood in an artery wall of the heart has been confirmed through X-ray (cardiac CT angiography). Afterwards, the patient lies on a padded testing table while contrast dye is injected into the arteries of the heart to show the exact location of the blockage. Then, a guide wire is passed from the femoral artery in the groin (or, at times, from the radial artery or brachial artery in the arm) to beyond the area of the artery that is being treated. It is followed by a balloon catheter and stent mechanism. The balloon inflates, putting the metal stent in place, so that the lumen of the artery is open and the red blood cells can flow freely.
