NCT04861519

Brief Summary

Prospective (analysis of retrospective data), multi-center, observational, single-arm study. This structure was selected as the "worst case" due to the fact that it represents real life usage of invasive FFR measurement is performed mostly in "gray zone" cases, which are that their severity cannot be determined intuitively and based on the physician eyeball. By using real-world historical data of invasive FFR, the analysis of the obtained data can ensure that the study results are expected to include invasive FFR results that are in the grey zone, when invasive FFR is used in real life and represent the real expected use of the product. Furthermore, the analysis of the data obtained in the studies with these similar devices measuring FFR obtained from angiograms was actually performed in a retrospective manner. That is, although the angiographic images and pressure wire recordings were obtained in real-time, due to the need to mark the vessel in real-time and obtain specific projections during the procedure without which the FFR cannot be calculated, the primary endpoint (sensitivity and specificity) and accuracy were determined in all studies by a post-hoc review by a similar independent QCA core laboratory. The invasive FFR data, as well as the software generated FFR data were reviewed post-hoc by a core laboratory or even at the company.

Outcome Measures

Primary Outcomes (1)

  • Evaluate the sensitivity and specificity of AutoCathFFR

    Co-primary endpoints are the sensitivity and specificity of the dichotomously scored AutocathFFR per vessel compared to the gold standard, invasive FFR measurements, where an FFR ≤ 0.80 is scored "positive" and an FFR \> 0.80 is considered "negative".

    Up to 2 months

Secondary Outcomes (7)

  • To assess the accuracy

    Up to 2 months

  • To assess the corelation bwtween invasive FFR and AutoCathFFR

    Up to 2 months

  • To assess the sensitivity and specificity

    Up to 2 months

  • To assess device success rate

    Up to 2 months

  • To assess the Usability of the AutocathFFR

    Up to 2 months

  • +2 more secondary outcomes

Study Arms (1)

adult subjects who underwent a clinically indicated invasive coronary angiography

adult subjects with stable angina, unstable angina or NSTEM1 who underwent a clinically indicated invasive coronary angiography and on whom invasive FFR has been measured in vessels with coronary lesions.

Other: Collecting invasive FFR measurements.

Interventions

Invasive FFR measurements from the patient's hospital records will be collected.

Sampling MethodProbability Sample
Study Population

C-Arm images from adult subjects with stable angina, unstable angina or NSTEM1 who underwent a clinically indicated invasive coronary angiography and on whom invasive FFR has been measured in vessels with coronary lesions.

You may qualify if:

  • patient specific:
  • Age \> 18 years.
  • Subjects with stable angina pectoris, unstable angina pectoris or NSTEM1 and in whom invasive FFR was performed to assess a non-culprit stenosis in at least one coronary artery.
  • Angiographic:
  • Subject underwent a clinically indicated Invasive Coronary Angiogram (ICA).
  • Subject underwent invasive FFR with IV or intracoronary Adenosine, Adenosine Triphosphate (ATP) or Papaverine used as hyperemic stimulus.

You may not qualify if:

  • Patient Specific:
  • Angiogram not obtained on an FDA cleared C-Arm angiography system.
  • Invasive FFR not obtained on an FDA cleared FFR catheter tip pressure transducer (a.k.a. pressure wire).
  • Vessel size less than 2 mm.
  • Subject presents with an acute infarct (STEM1) OR has documented prior STEMI on same side (right/left).
  • CTO in target vessel.
  • Prior CABG, heart transplant or valve surgery, prior TAVI/TAVR or severe left sided valvular disease.
  • Known LVEF ≤45%.
  • Arteries supplying akinetic or severe hypokinetic territories if already known based on prior imaging.
  • TIMI Grade 2 or lower at baseline.
  • Target lesion involves Left Main (stenosis \>50%).
  • PCI with stent in target vessel in past 12 months, or target vessel involves in-stent restenosis.
  • Severe, diffuse disease defined as the presence of diffuse, serial gross luminal irregularities present in the majority of the coronary tree.
  • Target coronary vessel provides collaterals to a chronically occluded vessel.
  • Angiographic:
