Background We assessed optimal intravascular ultrasound (IVUS) criteria for predicting functional significance of intermediate coronary lesions.Methods The analysis included 175 intermediate coronary lesions (151 patients) located in vessel diameters ≥2.5 mm.IVUS and invasive physiological assessment were performed before intervention.Fractional flow reserve (FFR) was measured at maximal hyperemia.Positive FFR was considered present at ＜0.8.
