During atherectomy, what is done?

Atherectomy involves inserting a catheter into a coronary artery and using a device at the tip to physically remove or debulk plaque from the artery lumen. The catheter carries cutting, shaving, grinding, or laser tools that break up and often remove the plaque, helping to restore the vessel’s diameter. This is different from balloon angioplasty, where a balloon compresses plaque against the vessel wall; from stenting, where a scaffold keeps the artery open after dilation; and from bypass procedures, where a graft is used to reroute blood flow around a blocked segment. So the description of using a catheter and surgical tools to remove plaque best captures what atherectomy does.
