Minor 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 کاملCusp height in aortic valves.
OBJECTIVES Successful aortic valve repair must normalize cusp and root dimensions. Limited information is available on the normal dimensions of human cusps, in particular the cusp height. METHODS The cusp height was measured intraoperatively in 621 patients during aortic valve repair procedures. A tricuspid anatomy was present in 329 patients and bicuspid in 286 patients. In addition, patient...
متن کاملFrequency by decades of unicuspid, bicuspid, and tricuspid aortic valves in adults having isolated aortic valve replacement for aortic stenosis, with or without associated aortic regurgitation.
BACKGROUND Aortic valve stenosis (with or without aortic regurgitation and without associated mitral stenosis) in adults in the Western world has been considered in recent years to most commonly be the result of degenerative or atherosclerotic disease. METHODS AND RESULTS We examined operatively excised, stenotic aortic valves from 932 patients aged 26 to 91 years (mean+/-SD, 70+/-12), and no...
متن کاملPathological Investigation of Congenital Bicuspid Aortic Valve Stenosis, Compared with Atherosclerotic Tricuspid Aortic Valve Stenosis and Congenital Bicuspid Aortic Valve Regurgitation
BACKGROUND Congenital bicuspid aortic valve (CBAV) is the main cause of aortic stenosis (AS) in young adults. However, the histopathological features of AS in patients with CBAV have not been fully investigated. METHODS AND RESULTS We examined specimens of aortic valve leaflets obtained from patients who had undergone aortic valve re/placement at our institution for severe AS with CBAV (n = 2...
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...
