NCT06075173

Brief Summary

The goal of this observational study is to evaluate diagnostic performance of resting full-cycle rate (RFR) in side branch lesion. We aims to evaluate whether the diagnostic performance of RFR in the side branch lesion is non-inferior compared to that in the main vessel lesion RFR and FFR measurements will be performed to define functional significance in patients with side branch lesion with or without main vessel lesion

Outcome Measures

Primary Outcomes (1)

  • diagnostic sensitivity of RFR in side branch lesions

    diagnostic sensitivity of RFR to predict FFR \< 0.80

    during index coronary angiography

Secondary Outcomes (1)

  • Specificity, positive predictability, negative predictability, diagnostic accuracy, area under the curve (AUC) value in side branch

Study Population

Patients with side branch lesion, who need functional evaluation

You may qualify if:

  • Patients with side branch lesion, who need functional evaluation

You may not qualify if:

  • Severe LV systolic dysfunction (LVEF \<30%)
  • Culprit vessel in acute coronary syndrome
  • Donor vessel to supply chronic total occlusion lesion of non-target vessel
  • Symptomatic valvular heart disease or cardiomyopathy
  • Too much overlapping or severe tortuosity to disrupt quantitative coronary analysis
  • Previous bypass surgery
