Assessing the Accuracy of the OptoWire DeuxTM in a Wire to Wire Comparison

The goal of the ACCURACY study is to assess the differences, if any, in FFR measurements made by the OptoWire Deux FFR guidewire by comparison of simultaneous data of two different OptoWire DeuxTM guidewires (group 1). In addition, the investigators will compare (group 2) the FFR measurements obtained from an OptoWire Deux FFR guidewire and compare it to the FFR measurement by a VERRATA-TM guidewire to assess coronary stenosis in the routine clinical practice.

Key information

About this study

This is a single center, prospective, non-blinded clinical investigation enrolling consecutive patients with coronary lesion candidate for FFR assessment. The study aim to assess the differences, if any, in FFR measurements made by the OptoWire Deux FFR guidewire by comparison of simultaneous data of two different OptoWire DeuxTM guidewires (group 1, n=30). In addition, The investigators will compare (group 2, n=15) the FFR measurements obtained from an OptoWire Deux FFR guidewire and compare it to the FFR measurement by a VERRATA-TM guidewire to assess coronary stenosis in the routine clinical practice. The clinical investigation will be conducted in the Centre Hospitalier de l'Université de Montréal (CHUM). No clinical follow-up is requested after the end of the procedure.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Single de novo coronary lesion or in-stent restenosis lesion with an operator assessed reference diameter ≥2.0 mm requiring FFR measurement based on the operator's clinical judgment

Exclusion criteria

  • Patients with ST-segment-elevation myocardial infarction (STEMI), culprit lesion of non-ST-segment-elevation myocardial infarction (NSTEMI), New York Heart Association class IV heart failure, suspected or visible thrombus, dissection or excessive calcification or tortuosity in the target vessel, or a stenosis in a bypass graft will be excluded.

Treatment and study plan

Drift assessment of OptoWire Deux FFR wire (1)

Device

Simultaneous data of two different OptoWire DeuxTM guidewires (group 1) to assess a single coronary stenosis and detect any difference if any.

Drift assessment of OptoWire Deux FFR wire (2)

Device

Simultaneous data of one Optowire Deux TM guide wires and one VERRATA-TM FFR wire (group 2) to assess a single coronary stenosis and detect any difference if any.

Primary outcomes

  1. delta FFR

    Time frame: Day 1

    To assess the magnitude of reading delta from wire to wire in a percutaneous coronary intervention

Secondary outcomes

  1. Drift recording

    Time frame: Day 1

    The rate of significant drift, defined as Pd/Pa <0.97 or >1.03

  2. Delta from guidewire to guidewire

    Time frame: Day 1

    Assess the magnitude of reading delta from guidewire to guidewire prior to equalization.

  3. Stents

    Time frame: Day 1

    The number of stents used.

  4. Stents on FFR wire

    Time frame: Day 1

  5. Workhorse guidewire

    Time frame: Day 1

    Number of Workhorse guidewire used.
