Key result
In vitro models, computational fluid dynamics, and 4D flow MRI provide insights into type B aortic dissection hemodynamics, though their accuracy and validity require further study for clinical use.
Why the study?
In vitro models and CFD simulations for TBAD hemodynamics are rarely used in clinical practice due to concerns about their accuracy and reliability.
This review highlights the importance of validating in vitro and computational hemodynamic models of Type B aortic dissection using 4D-MRI to improve their clinical applicability for TEVAR.

Validation of TBAD hemodynamic models with 4D flow MRI remains essential; leaves open their clinical adoption for TEVAR planning.
Type B aortic dissection (TBAD) is associated with high mortality. Multiple in vitro models and computational fluid dynamics (CFD) simulations have been used to mimic the hemodynamic characteristics of TBAD to inform more effective therapeutic strategies. However, the results of these experiments are rarely used in clinical practice due to concerns about their accuracy and reliability. The development of 4-dimensional magnetic resonance imaging (4D-MRI) allows to verify the accuracy of the results of in vitro models and CFD simulations. This review provides an overview of the strengths, limitations, and accuracy of in vitro models, CFD simulations, and in vivo 4D flow MRI for the study of TBAD hemodynamics.Clinical Impact1. Hemodynamic of TBAD is important to improve the long-term outcome of TEVAR.2. This review provides an overview of the in-vitro for the hemodynamic study of TBAD.3. The accuracy and validity of in-vitro TBAD experiments should be further studied.
