Atherectomy
Atherectomy, commonly known as rotoblator, is an ideal treatment for bulky coronary lesions. Debulking via rotoblator allows for cutting and excision of plaque, a distinct advantage over plaque displacement.

Directional atherectomy uses a miniature rotating blade to cut out the fatty deposit and remove it from the body - a method that is beneficial in only about 1 percent of cases. Rotational atherectomy uses a diamond-studded drill bit to pulverize blockages. This is particularly useful for calcified ridge blockages that are present in about 5 percent of cases.
