Diagnostic accuracy of CTA-based quantitative hemodynamics for functional assessment in coarctation of aorta.

OBJECTIVE: ) in non-invasively estimating peak systolic pressure gradients (PG) for patients with suspected coarctation of the aorta (CoA) on a larger scale. MATERIALS AND Diagnostic accuracy, sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) were calculated to evaluate diagnostic performance, and intraclass correlation coefficient (ICC) and Bland-Altman analysis were used to evaluate the agreement. CONCLUSION: may serve as a reliable tool for hemodynamic functional assessment in patients with early suspected CoA to guide clinical considerations of invasive catheterization.
