The correlation between fractional flow reserve (FFR) and intravascular ultrasound (IVUS) metrics including minimal lumen area (MLA), plaque burden and morphology remain a matter of debate.Between June 2008 and May 2013, 132 intermediate stenoses in 109 patients were assessed by FFR, IVUS and quantitative angiography. Receiver-operating characteristic (ROC) curve analyses were used to identify MLA/lesion length/plaque burden cut-off values predictive of FFR <0.80.FFR <0.80 was observed in 39 lesions. In the entire cohort, MLA value <2.70mm(2) had 79.5
