Also known as: Directional Coronary Atherectomy (DCA)
Duration: About 1 to 2 hours
An atherectomy is a term for a group of procedures that use sharp blades to remove plaque (fat and calcium buildup) from clogged arteries.
A coronary atherectomy removes plaque from the coronary arteries. It is a minimally invasive procedure that follows the cardiac catheterization to improve blood flow to your heart muscle when severe calcium and/or fat builds up in the coronary arteries that an insertion and expansion of a stent is not possible.
- To treat severe coronary artery disease (CAD)
- To treat cases where a previously placed stent has become narrowed again
Preparing for the procedure:
How the procedure is performed:
- Firstly, a diagnostic cardiac catheterization is performed to check for any blocks in the coronary arteries. A catheter (a thin, long tube) is placed in either your arms, legs, or groin and is monitored by an x-ray camera until it reaches the coronaries.
- A contrast dye is then infused so that the arteries can be seen.
- If an artery is blocked, you may require a coronary atherectomy to remove plaque from the clogged arteries.
- Rotational Atherectomy – involves removing plaque by using a rotating catheter with a diamond-tipped blade
- Orbital Atherectomy – involves using the Diamondback 360° Orbital Atherectomy System to remove the plaque with orbital motion
- Laser Atherectomy – uses a laser-tipped catheter to treat complex blockages
- Once the atherectomy is completed, your cardiologist will determine if a balloon angioplasty with or without stent placement would be required.
