ANGIOPLASTY and STENTING
Cholesterol can accumulate on the interior lining of the coronary arteries and form deposits referred to as cholesterol plaques. As these deposits progressively increase in size they can narrow or even completely block the arteries lumen or opening.  Angioplasty is a interventional procedure wherein a special catheter is used to dilate or open narrowed or obstructed coronary artery. The angioplasty catheter is a narrow, hollow, flexible tube that has a balloon near the end of it.
