Abstract:Ascending thoracic aortic aneurysms (ATAA) are defined by a silent dilation of the ascending aorta (AA). Although maximal aortic diameter is currently used for surgery planning, a high proportion of patients with low diameters ending up with aortic dissection. Our purpose was to propose a fine and comprehensive quantitative evaluation of pressure-flow-wall interplay from 4D flow MRI data in the setting of aortic dilation.We studied 12 patients with ATAA (67±14 years, 7 male) and 12 healthy subjects (63±12 year… Show more
