Can a computational fluid dynamic model using IVUS 3D anatomical data accurately estimate FFR?
Answers are grounded in this paper and cite their sources.
Computational fluid dynamics applied to IVUS 3D anatomical data shows promise for estimating FFR, though further refinement is needed for routine clinical use.
IVUS measurements of luminal area have only modest correlations to FFR. This study used IVUS 3D anatomical data in a computational fluid dynamic model to estimate FFR with a reasonable degree of accuracy. Further studies are needed to refine the models to make them more accurate and practical for routine use.
