Aortic stiffness and aortic dilation in infants and children with tetralogy of Fallot before corrective surgery: evidence for intrinsically abnormal aortic mechanical property

Abstract

The present study highlighted the intrinsic abnormality of the mechanical property of the aortic wall as a feature of aortopathy in TOF. The study also indicated that aortic volume overload and, to a lesser extent, intrinsically high aortic stiffness correlated significantly with aortic dilation in TOF.
