Fig 2 Geometric description of the aortic dissection models. Each subject has two pictures: right-anterior view of the reconstructed model (left) and transparent view (right). The primary tear can be seen clearly from the transparent views. AD, Aortic dissection.

Fig 3 Particle paths of blood flow in each aortic dissection model demonstrating accelerated flow through the tear and false lumen complex flow (right-anterior view [left] and left-posterior view [right]). Paths are color coded based on velocity; red is the highest velocity, blue is the lowest. AD, Aortic dissection.

Fig 7 Time-averaged wall shear stress (TAWSS) contours in the aortic dissection models (right-anterior view [left] and left-posterior view [right]). Highest TAWSS was found at the entry tear site where blood flow is accelerated and velocity is high.
