What this trial studies

This observational multicenter cohort study aims to evaluate the safety and effectiveness of rotational atherectomy in patients with calcified coronary lesions undergoing percutaneous coronary intervention (PCI). Participants will provide informed consent for data collection, which will include demographics, clinical data, and follow-up results. The study will aggregate data from multiple centers across Asia to assess procedural outcomes and complications associated with this treatment approach. The findings will help to understand the representativeness of the data collected and the effectiveness of rotational atherectomy in this patient population.

Who should consider this trial

Good fit: Ideal candidates include patients with clinically indicated PCI and moderate to severe coronary calcification.

Not a fit: Patients who decline to give consent or do not meet the angiographic criteria for calcification will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve treatment outcomes for patients with severe coronary calcification requiring PCI.

How similar studies have performed: Previous studies have shown that rotational atherectomy can be a safe adjunctive procedure for treating heavily calcified lesions, indicating potential success for this approach.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Able to understand and sign an informed consent form
* Presence of clinical indication for percutaneous coronary intervention (PCI) and/or stent placement
* Subjects willing to comply with all research and follow-up requirements.
* Angiographic criteria (ONE of the following criteria MUST be met)

  1. Target lesions visually have at least moderate calcifications\*
  2. Target lesion balloon dilatation failure
  3. Inability of devices (microcatheters, balloons or stents) to pass through the target lesion.
* Procedural criteria

  1. All patients treated with RA with or without other forms of debulking therapy

     * Moderate calcification is defined as radio-opacities noted only during cardiac cycle prior to contrast injection whereas severe calcification is defined as radio-opacities seen without cardiac motion prior to contrast injection, usually affecting both sides of the arterial lumen.

Exclusion Criteria:

* Decline to give consent
