During the Procedure

  • A guide wire is inserted through the guiding catheter (a thin, flexible tube) and moved to the narrow spot in your artery. Your doctor tracks its movement on an angiogram, a special kind of x-ray.

  • Then, a special atherectomy catheter carrying a grinding device is positioned at the narrow spot in your coronary artery.

  • An abrasive burr near the tip of the catheter grinds the plaque into small particles that float harmlessly away in the bloodstream.

Call Your Doctor If:

  • You have angina (chest pain).

  • The insertion site has pain, swelling, redness, bleeding, or drainage.

  • You have severe pain, coldness, or a bluish color in the leg or arm that held the catheter.

  • You experience blood in your urine, black or tarry stools, or any other kind of bleeding.

  • You have a fever over 101.0°F.

After the Procedure

  • You'll need to remain lying down for 6-12 hours.

  • If the insertion site was in your groin, you may need to lie down with your leg still for several hours.

  • A nurse will check the insertion site and your blood pressure. Before going home, you may have a chest x-ray and other tests.

  • You usually remain in the hospital for several hours or overnight.
