Aortic annulus and root characteristics in severe aortic stenosis due to bicuspid aortic valve and tricuspid aortic valves: Implications for transcatheter aortic valve therapies

Abstract

Bicuspid aortic valves have a larger annulus size, sinus of Valsalva and ascending aorta dimensions. In addition, the BAV aortic annuli appear circular and most will fit currently available commercial valved stents.
