The Functional Severity Assessment of Coronary Stenosis Using Coronary Computed Tomography Angiography-Based Myocardial Mass at Risk and Minimal Lumen Diameter

Figure 5

The areas under the receiver operating characteristic curve of myocardial mass at the risk-to-minimal lumen diameter ratio (MMAR/MLD) for FFR ≤ 0.8 in all culprit lesions (a) and in the culprit lesions in the right coronary (b), left anterior descending (c), and left circumflex arteries (d). In addition, the curves in the culprit lesions in the proximal (e) and nonproximal left anterior descending arteries (f). Each graph shows the optimum cut-off value (specificity, sensitivity). PPV: positive predictive value; NPV: negative predict value.
