Diastolic Fractional Flow Reserve to Assess the Functional Severity of Moderate Coronary Artery Stenoses

Abstract

The close similarity of the sensitivity and specificity of FFR and d-FFR, around almost identical cutoff values (0.75 versus 0.76), confirms the physiological validity of FFR as a clinical standard. In clinical practice, FFR remains the index of choice for assessment of the functional severity of moderate coronary artery stenoses.
