Coronary Atherectomy is a procedure that removes fatty material (plaque) from your coronary arteries so more blood can get to your heart. A smaller catheter with a drill or spinning knife on the tip is put inside the guide catheter. Once this catheter reaches the narrowed part of the artery, the doctor will use the drill or knife to shave or cut the plaque from your artery walls to allow a stronger flow of blood through the artery.
