Angioplasty is a mechanical procedure to open arteries or veins, which have become extremely narrowed or blocked as a result of atherosclerosis. To perform an angioplasty an deflated balloon on a guide wire, known as a balloon catheter, is passed into the narrowed locations and then inflated to a fixed size using water pressures some 75 to 500 times normal blood pressure (6 to 20 atmospheres). The balloon open up the blood vessel as it crushes the fat deposits for improved flow, and the balloon is then deflated and withdrawn.

Blockages in the arteries may be caused by hypertension, diabetes, sedentary lifestyle, smoking, high cholesterol levels, diets high in saturated fats, and cardiovascular disease. Removing blockages is done with angioplasty. Angioplasties are safer than bypass surgery and according to statistics less than 1% of people die from complications after this procedure.
