Visualization 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 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 کاملMinor congenital variations of cusp size in tricuspid aortic valves. Possible link with isolated aortic stenosis.
Clinically isolated aortic stenosis is most commonly caused by a congenitally malformed aortic valve. Many elderly patients with isolated aortic stenosis have a tricuspid aortic valve. It has been suggested in the past that inequalities in individual cusp size could be a factor leading to the development of the stenoses in these cases. In this study the width and height of individual aortic val...
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 کاملA new self-expanding aortic stent valve with annular fixation: in vitro haemodynamic assessment.
OBJECTIVE Balloon-expandable stent valves require flow reduction during implantation (rapid pacing). The present study was designed to compare a self-expanding stent valve with annular fixation versus a balloon-expandable stent valve. METHODS Implantation of a new self-expanding stent valve with annular fixation (Symetis, Lausanne, Switzerland) was assessed versus balloon-expandable stent val...
