Atherectomy is performed to open clogged arteries by removing plaque buildup.
During the procedure, a special catheter carrying a grinding device is inserted through an artery in the groin or arm and carefully positioned at the narrowed or blocked spot in the coronary artery. The grinding device then cuts away the plaque buildup and leaves a much smoother artery wall. As a result, the blood flow through the coronary artery is significantly improved.
