(A) Preoperative magnetic resonance angiogram and four-dimensional magnetic resonance imaging image sequences of the thoracic aorta utilized for computational modelling. (B) Computational mesh derived from magnetic resonance angiogram/four-dimensional magnetic resonance imaging images. (C) Flow field calculated from computational fluid dynamics. The ascending thoracic aortic aneurysm (D) was divided into areas of interests: (E) outer curvature proximal, outer curvature middle and outer curvature distal, and (F) inner curvature. (G) Complete ring of resected aorta. (H) Squares were sampled for (I) bi-axial tensile testing and rectangles were sampled for (J) delamination testing.
