15 صفحه اولAscending Aortic Wall Cohesion: Comparison of Bicuspid and Tricuspid Valves
Objectives. Bicuspid aortic valve (AV) represents the most common form of congenital AV malformation, which is frequently associated with pathologies of the ascending aorta. We compared the mechanical properties of the aortic wall between patients with bicuspid and tricuspid AV using a new custom-made device mimicking transversal aortic wall shear stress. Methods. Between 03/2010 and 07/2011, 1...
متن کاملVisualization of flow in the ascending aorta: bicuspid aortic valves compared to tricuspid aortic valves
Methods Our prospective matched-pair study included 18 patients (median age 25 years, range 8 44 years) with a native bicuspid aortic valve and normal diameters of the ascending aorta, without stenosis or insufficiency of the aortic valve and no coarctation of the aorta. All of the 18 patients were ageand sexmatched with 18 controls with a tricuspid aortic valve. All patients with BAV were othe...
