About this study

Official title: Comparison of Non-Invasive Vessel Fractional Flow Reserve Calculated From Angiographic Images Versus Fractional Flow Reserve in Patients With Intermediate Coronary Artery Stenoses

This is a prospective, randomized, controlled, multicenter, open-label study designed to assess whether vFFR is non-inferior to FFR in assessment of intermediate coronary stenosis in terms of the occurrence of MACE during 12 months after randomization.

Read the detailed description

Coronary angiography is insensitive to assess the physiologic significance of a coronary stenosis. Therefore, clinical guidelines support the use of pressure-derived fractional flow reserve (FFR) to assess the hemodynamic significance of coronary stenosis. Nevertheless, the penetration of FFR in clinical routine continues to be limited by its requirement for pharmacological vasodilation, prolonged procedure time and adverse systemic effects from adenosine.

Vessel-FFR (vFFR) is a novel method for evaluating the functional significance of coronary stenosis by calculation of the pressure drop in the vessel based on computation of two angiographic projections. The vFFR values at each point along the vessel are color-coded and superimposed on the 3D epicardial model and cut-off values of ≤0.80 identical to standard invasive FFR apply.

These developments may translate towards more physiology guided intervention bearing the potential to improve clinical outcomes in patients with stable CAD. The ability to derive FFR values from routinely performed coronary angiograms, without the practical drawbacks that limit invasive techniques, could have an important impact on daily clinical practice.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Measurement of FFRDiagnostic test

    Invasive measurement of fractional flow reserve (FFR) using a pressure wire during maximal hyperemia (typically induced by adenosine) to guide revascularization decisions.

  • Measurement of vFFRDiagnostic test

    Computation of vessel fractional flow reserve (vFFR) from coronary angiograms using 3D quantitative coronary angiography (3D-QCA) software to guide revascularization decisions.

Study groups in NCT03497637
Study groupRoleWhat they receive
vFFR-guided PCIActive comparatorPatients undergo percutaneous coronary intervention (PCI) guided by vessel fractional flow reserve (vFFR). vFFR is computed using 3D angiographic reconstruction software to assess the hemodynamic significance of coronary stenoses without the use of an invasive pressure wire or hyperemic agents.
Receives: Diagnostic Test: Measurement of vFFR
FFR-guided PCIActive comparatorPatients undergo percutaneous coronary intervention (PCI) guided by standard invasive fractional flow reserve (FFR). FFR is measured using an intracoronary pressure wire under maximal hyperemia to assess the hemodynamic significance of coronary stenoses.
Receives: Diagnostic Test: Measurement of FFR

What is being measured

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

  1. Major Adverse Cardiac Event (MACE) rate

    composite of cardiac death, non-fatal myocardial infarction or unplanned revascularization

    Measured: 1 year

Secondary outcomes (6)
  1. MACE during long-term follow-up

    Measured: 2 and 5 years

  2. Each component of the primary endpoint assessed by structured telephone interview and verification by hospital reports

    Measured: 1, 2 and 5 years

  3. Repeat revascularization (PCI or CABG) assessed by structured telephone interview and verification by hospital reports in case of event

    Measured: 1, 2 and 5 years

  4. All-cause mortality

    Measured: 1, 2 and 5 years

  5. Cross-over rate from the one strategy to the other

    Measured: at intervention

  6. Number of analyzable lesions in both treatment arms

    Measured: at intervention

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Major Adverse Cardiac Event (MACE) rate (time frame: 1 year). 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 NCT03497637, which also lists 1 linked publication.

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 29 Oct 2026.
