Calcification of bicuspid aortic valves.
Over the past decade, our concept of the pathogenesis of calcific aortic valve disease has undergone a major transformation. We now recognise that calcific valve disease is the end stage of an active disease process and is not caused by “wear and tear” of the valve tissue. Immunohistochemical studies of trileaflet aortic valves with varying degrees of valve stenosis have demonstrated the presen...
متن کاملAscending 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...
متن کاملRisk and outcomes of aortic valve endocarditis among patients with bicuspid and tricuspid aortic valves
OBJECTIVE Patients with structural abnormalities of cardiac valves, including bicuspid aortic valve (BAV), are said to be at higher risk of infective endocarditis (IE). We sought to determine the risk of IE of the BAV compared with the tricuspid aortic valve (TAV) and to determine the risk of aortic valve replacement and mortality after IE. METHODS From medical records of two US and one Itali...
متن کاملCARDIOVASCULAR MEDICINE T lymphocyte infiltration in non-rheumatic aortic stenosis: a comparative descriptive study between tricuspid and bicuspid aortic valves
Background: The two most common causes of aortic stenosis are primary “degenerative” calcification of tricuspid aortic valves and secondary calcification of congenital bicuspid valves. T lymphocyte infiltration occurs in stenotic tricuspid aortic valves, indicating an inflammatory component, but it has not been shown whether it also occurs in stenotic bicuspid valves. Objective: To compare non-...
