  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patients with stable or unstable coronary artery disease due to atherosclerosis involving a major bifurcation site, who undergo diagnostic or interventional invasive percutaneous coronary procedures with the use of optical coherence tomography (OCT) based on operator's choice.

Who may be able to join

  • Patients with stable or unstable coronary artery disease;
  • TIMI 3 on both MV and SB;
  • MV visual diameter > 2.5 mm;
  • SB visual diameter > 2.0 mm;
  • Documentation of angiographically-critical (visually estimated percentage diameter stenosis ≥80% <100%) coronary lesion treated by PCI and underwent post-PCI OCT assessment or angiographically-intermediate (visually estimated percentage diameter stenosis ranging between 30-80%) lesion in the MV considered suitable for conservative management (myocardial revascularization not planned).

About this study

Official title: A Multicentre Prospective Study on the Role of Fluid Dynamics OCT-based REconstruction of Coronary Atherosclerosis in bifurcationS to Predict ouTcome

Investigator-initiated, international, multicentre, observational study with two cohorts.

The two study cohorts will be:

Read more

Cohort A: to understand if the local blood flow patterns (associated with low WSS), as evaluated by computational fluid dynamic tools from combined angiographic and OCT invasive images, may better predict the clinical outcome of patients with bifurcated coronary lesions treated by PCI.

Cohort B: to understand if the local blood flow patterns (associated with low WSS), as evaluated by computational fluid dynamic tools from combined angiographic and OCT invasive images, may better predict the clinical outcome of patients with sub-critical bifurcated lesions managed conservatively.

Coronary angiography and OCT images will be combined to obtain a three-dimensional model of the diseased coronary vessels that will be used to calculate the local blood flow patterns and the time-averaged WSS at the bifurcated lesion level by using computational fluid dynamics software.

Baseline (in patients both managed conservatively and treated by PCI) and post-PCI (in patients treated by PCI) images will be processed.

Being tested
Coronary angiography and optical coherence tomography

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Target bifurcation failure (TBF)

    • Target bifurcated lesion-related major adverse coronary event (MACE) defined as the composite of:
    • cardiac death
    • myocardial infarction (MI) not clearly related with another vessel
    • target vessel revascularization (TVR)

    Measured: 1,6,12,18,24 and 36 months

Secondary outcomes (2)
  1. Target vessel failure

    • In the absence of target bifurcated lesion-related MACE, target bifurcated lesion angiographic failure defined, in patients treated by PCI, as: > 50% restenosis on the main vessel (MV) or TIMI (Thrombolysis In Myocardial Infarction) flow < 3 on the side branch (SB) at angiography eventually performed during the clinical course.

    Measured: 1,6,12,18,24 and 36 months

  2. Bifurcated lesion angiographic failure

    • Cardiac death
    • MI
    • TVR
    • Definite or probable stent thrombosis

    Measured: 1,6,12,18,24 and 36 months

Questions about this trial

What is this clinical trial studying?

An observational study of Atherosclerosis, Coronary, run by Catholic University of the Sacred Heart at 1 site in Italy.

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 5 inclusion and 15 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: status not confirmed, as of the sponsor's last update on 2 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Francesco Burzotta, MD (+39 3494295290, francesco.burzotta@unicatt.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Target bifurcation failure (TBF) (time frame: 1,6,12,18,24 and 36 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 2 Jun 2017.
