In the Effects of Debulking on Restenosis (EDRES) trial, 150 patients were randomized to stenting alone versus rotational atherectomy with stenting. First, it was capable of removing obstructive atherosclerotic lesions. Rotational atherectomy was first used in 1988 and uses high-speed (140,000–180,000 rpm) rotation to ablate inelastic plaque, resulting in debris with an average size of < 5 μm. directional versus rotational During a rotational atherectomy, a vascular specialist navigates a catheter fitted with a Rotablator™ device on the tip (looks similar to a football shape) to where the blockage is located.

Atherectomy is a minimally invasive technique for removing atherosclerosis from blood vessels within the body. Directional coronary atherectomy involves a specially made minimally invasive device with a tiny cutting tip that rotates at high speed to cut away plaque in the artery. When it comes to atherectomy, trust the Rotablator System for proven patient outcomes. In a rotational atherectomy, Mount Sinai Heart interventional cardiologists use a revolving instrument to break up calcified plaque that is clogging a coronary artery.
