About this study
Official title: Evaluation of the Safety and Efficacy of Orbital Atherectomy (OA) for Calcified Lesions in Patients With Coronary Artery Disease: The Lower Silesian Orbital Atherectomy Registry (LOAR)
The Lower Silesian Orbital Atherectomy Registry (LOAR), is an observational registry collecting all consecutive cases of percutaneous coronary intervention (PCI) performed with the support of the Orbital Atherectomy Device due to the presence of calcified lesion in coronary arteries. Data will be collected in two cooperating cardiac centers (Department of Cardiology, The Copper Health Center, Lubin, Poland, and Department of Cardiology, Provincial Specialized Hospital in Legnica, Poland).
Read the detailed description
The study population consisted of all consecutive patients with severely calcified coronary lesions undergoing percutaneous coronary intervention (PCI) with the Orbital Atherectomy Device at two cooperating cardiac centers (Department of Cardiology, The Copper Health Center, Lubin, Poland, and Department of Cardiology, Provincial Specialized Hospital in Legnica, Poland). All study patients had a clinical indication for PCI based on current European Society of Cardiology (ESC) revascularization guidelines, with local heart team support where appropriate.
The decision to perform OA-assisted PCI was left to the discretion of the operator, based on clinical and angiographic features with a concomitant assessment of calcification. Only patients with moderate or severe calcification were enrolled. Calcification severity was defined either by angiographic assessment or by intravascular assessment using intravascular ultrasound (IVUS) and/or optical coherence tomography (OCT). All patients were thoroughly informed about all therapeutic options and PCI-related risks before giving written consent.

What participants receive. In a randomised study each person is assigned to one group by chance.
PCI Facilitated with Orbital Atherectomy DeviceProcedure or surgery
Percutaneous coronary intervention for coronary artery disease supported by the Orbital Atherectomy Device
| Study group | Role | What they receive |
|---|---|---|
| OA Intervention | All consecutive patients with moderate/ severely calcified coronary lesions who underwent PCI facilitated by the Orbital Atherectomy The decision to perform orbital atherectomy was left to the operator's dissertation after the detection of a moderate/severely calcified lesion. Angiographic calcification was classified as moderate when it involved between 30% and 50% of the reference lesion diameter, and severe when it occupied over 50% of the reference diameter. When the initial assessment was based on IVUS finding lesion had to reach at least 2 points in the IVUS calcium score. There were no angiographic exclusion criteria regarding lesion anatomy such as the length, tortuosity, severity, or location. All procedural features(use additional lesion preparation technique; stent implantation parameters, periprocedural pharmacological therapy, use of intravascular imaging along with the left ventricular support device) were left to the discretion of the operator. Receives: Procedure: PCI Facilitated with Orbital Atherectomy Device |
What is being measured
The primary outcome is the main question the study is designed to answer.
The rate of patients who achieved The Clinical Success
Clinical success was defined as effective stent deployment without significant stent under expansion and the presence of Thrombolysis in Myocardial Infarction (TIMI) 3 flow at the end of the procedure.
Measured: Evaluation at discharge (assessed up to day 10)
Incidence of Treatment-Emergent Adverse Events
The safety outcomes were defined as procedural complications(coronary perforation, slow- or no-reflow, new coronary thrombus, ventricular arrhythmias, vessel closure, and device failure).
Measured: Evaluation at discharge (assessed up to day 10)
Secondary outcomes (1)
Major adverse cardiac and cerebrovascular events (MACCE)
MACCE was defined as acute coronary syndrome, cerebrovascular events, major bleeding, need for repeated revascularization, or death.
Measured: Final assessment - 5 years after the initial hospitalization; followed by evaluation every 6 months from the end of the hospitalization until the final assessment (5 years)

Questions about this trial
What is this clinical trial studying?
An observational study of Safety Issues and Efficacy, Self, run by Miedziowe Centrum Zdrowia SA at 2 sites in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 21 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Piotr Rola, MD; PhD (+48767211446, piotr.rola@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The rate of patients who achieved The Clinical Success (time frame: Evaluation at discharge (assessed up to day 10)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06451146, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Aug 2024.
