Figure 2:

FFR_CT appropriateness and interpretation recommendation. * = Low risk: patients either without coronary disease or with maximum stenosis less than 30%. Intermediate risk: patients with one or more intermediate range stenosis (30%–69%). High risk: patients with left main, three-vessel disease or stenosis 70% or greater. Anatomic characteristics beyond stenosis severity, patient symptoms, and suitability of revascularization may influence decisions on management after coronary CT angiography (CTA). ** = Posttest risk stratification: Test results must always be evaluated in their clinical context, taking into account patient symptoms and preferences as well as high-risk anatomic features and likelihood of revascularization.
