Marked disparity in mechanical wall properties between ascending and descending aorta in patients with tetralogy of Fallot

Abstract

Consistent with the known histopathological disparity between the media of the ascending and descending aortas, aortic stiffness is markedly increased in the proximal but not in the distal aorta of TOF. These results suggest that aortic wall stiffness is a potentially useful clinical marker of aortic dilation in patients with TOF.
