Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Major adverse cardiovascular event (MACE) (primary safety endpoint)

    The composite of any ischemia-driven target lesion revascularization (TLR), myocardial infarction (MI), or cardiac death. Periprocedural myocardial infarction, defined as in patients with normal baseline CK-MB, the peak CK-MB measured within 48 hours of the procedure rises to ≥ 10 x the local laboratory ULN, or to ≥ 5 x ULN with new pathologic Q-waves in ≥ 2 contiguous leads or new persistent LBBB (according to SCAI definition. J Am Coll Cardiol 2013;62:1563-70)

    30 days

  • Procedural success rate (primary efficacy endpoint)

    A mean lesion diameter stenosis \<30% in 2 near-orthogonal projections with TIMI 3 flow, as visually assessed by the physician, without the occurrence of in-hospital MI, target vessel revascularization (TVR), or cardiac death

    Peri-procedural

Secondary Outcomes (13)

  • TLR rate

    At 30 days and 12 months post-index procedure

  • Target lesion failure (TLF) rate

    At 30 days and 12 months post-index procedure

  • TVR rate

    At 30 days and 12 months post-index procedure

  • Target vessel failure (TVF) rate

    At 30 days and 12 months post-index procedure

  • MI rate

    At 30 days and 12 months post-index procedure

  • +8 more secondary outcomes

Other Outcomes (4)

  • Rate of arterial perforation (rotational atherectomy related or non-related)

    Peri-procedural

  • Rate of abrupt coronary occlusion (including dissection and thrombosis)

    Peri-procedural

  • Rate of significant coronary dissection (NHLBI types C-F)

    Peri-procedural

  • +1 more other outcomes

Rotational Atherectomy

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

This national, multi-center, prospective, observational study will enroll at least 1000 subjects in about 18 to 20 sites in China. All subjects who are candidates for PCI, signed the informed consent form and eligible to receive the treatment using RotablatorTM Rotational Atherectomy System will be evaluated for enrollment in this study.

You may qualify if:

  • Age ≥18 years old
  • Subject who is clinically indicated for PCI/stenting
  • Written informed consent
  • Subject is willing to comply with all protocol-required follow-up evaluation
  • Target lesion is moderately to severely calcified by visual estimate
  • Unsuccessful balloon dilatation of the target lesion
  • Unsuccessful passage of device(s) (microcatheter, balloon, or stent) across the target lesion

You may not qualify if:

  • Subject has clinical symptoms and/or electrocardiogram (ECG) changes consistent with acute MI within 2 weeks
  • Subject has any of the following angiographic findings:
  • Thrombus present in the target vessel (by visual estimate)
  • Significant dissection present in the target vessel (NHLBI types C-F)
  • Lesion angulation \> 60°(by visual estimate)
