Rotational atherectomy (RA) facilitates percutaneous coronary intervention for complex de novo lesions with severe calcification. Some observational studies and a small randomized trial indicated that a strategy of routine RA did not conferred reduction in restenosis or MACE, but these studies are limited by missing follow-up, insufficient power to compare outcomes, and confounding factors in the RA group (long lesion length, etc.). With recent developments in medical therapy, advances in design and delivery of drug-eluting stents (DES), and advances in noninvasive and intravascular coronary imaging, the use of RA in current real-world practice remains to be well determined. We aimed to compile real-world clinical outcomes data for the RotablatorTM Rotational Atherectomy System in routine clinical practice in China.
