Four Stanford type-A aortic dissection digital models of different size and location of the tear (the size and location of the re-entry in the distal descending aorta are fixed). In model A11 and A21, the entry tears are located near the ascending aorta, and the RA are 1 and 2, respectively; In the model B11 and B21, the entry tears are located near proximal descending aorta and the RA are again assigned to 1 and 2, respectively
