Rotational atherectomy facilitates percutaneous coronary intervention for complex de novo lesions with severe calcification. A strategy of routine rotational atherectomy has not, however, conferred reduction in restenosis or major adverse cardiac events. As it is techically demanding, rotational atherectomy is also uncommon. At this 25-year anniversary since the introduction of rotational ...
