Rota China Registry

August 4, 2023 updated by: Shao-Ping Nie, Beijing Anzhen Hospital

A Post-Approval Study of the RotablatorTM Rotational Atherectomy System in China

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
