NCT04569669

Brief Summary

The device involved in this trail is a diagnostic software with a Prospective, Multicenter, Self Controlled design. FFRCT diagnostic performance was calculated by CardioSimFFRct Analysis software, and the diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive performance of FFRCT for myocardial ischemia were calculated per-patient level and per-vessel level with invasive FFR value as gold standard.

Outcome Measures

Primary Outcomes (1)

  • Sensitivity and specificity (subject level) of FFRCT

    Sensitivity and specificity (subject level) for predicting the functional significance of coronary artery stenosis using CT-Derived Fractional Flow Reserve Score Analysis Software.

    Measurement at Procedure/Baseline Visit

Secondary Outcomes (5)

  • AUC between FFRCT vs. FFR

    Measurement at Procedure/Baseline Visit

  • Sensitivity and Specificity between FFRCT vs. FFR

    Measurement at Procedure/Baseline Visit

  • Accuracy (lesion level and subject level) between FFRCT vs. FFR

    Measurement at Procedure/Baseline Visit

  • Positive Predictive Value (PPV) between FFRCT vs. FFR

    Measurement at Procedure/Baseline Visit

  • Negative Predictive Value (NPV) between FFRCT vs. FFR

    Measurement at Procedure/Baseline Visit

Study Arms (1)

Patients diagnosed with Coronary Artery Disease(CAD)by CCTA

EXPERIMENTAL

Patients admitted to hospital with the diagnosed of CAD by CCTA and who accept to participate to the study will undergo the invasive coronary angiography, fractional flow reserve (FFR) will be measured during the invasive coronary angiography.Outcome measures were comparing FFRct to FFR.

Diagnostic Test: FFR and FFRCT

Interventions

FFR and FFRCTDIAGNOSTIC_TEST

All the patients will undergo computed coronary tomography angiography to analysis FFRCT . Then FFR will be measured during invasive cardiac catheterization.
