ascending aorta has elongated considerably, and, thus, become curved, obliquity of theaxial planein respect to thecenterlineof the aorta will introduce a moderate discrepancy of several millimeters; the axial measurements will “overestimate” the diameter relative to the double oblique measurements. ...
Ascending aorta measurements as assessed by ECG-gated multi-detector computed tom- ography: a pilot study to establish normative values for transcatheter therapies. Eur Radiol 2009;19:664-669.Lu TC, Huber CH, Rizzo E, Dehmeshki J, von Segesser LK, Qanadli SD. Ascending aorta measurements as...
Perioperative stroke is a devastating complication after coronary artery bypass graft (CABG) surgery, with atherosclerosis of the ascending aorta as important risk factor. During surgical manipulation, detachment of plaques can lead to consecutive embolization into brain-supplying arteries. High-pitch comput...
L. Evaluation of blood flow velocity in the ascending aorta and main pulmonary artery of normal subjects by Doppler echocardiography. Am. Heart J. 107, 310–319 (1984). 38. Martin, L. J., Hinton, R. B., Zhang, X., Cripe, L. H. & Benson, D. W. Aorta measurements are heritable...
16 reported aortic dilatation and reduced aortic distensibility as a marker of an intrinsic aortopathy in TOF, compared with normal controls. Alterations in elastic properties were especially found in the proximal aorta,17 and were thought to precede aortic dilation and to increase LV afterload.18,...
22 Aortic size was measured in the parasternal long axis view at end diastole at 4 levels: (1) aortic annulus, (2) sinuses of Valsalva, (3) sinotubular junction, and (4) ascending aorta (2-3 cm above the sinotubular junction at the maximal visualized diameter). Aortic measurements, ...
resulting differences between Doppler and catheter measurements may be predicted from Doppler velocity, aortic valve area and size of the ascending aorta.doi... Helmut Baumgartner MD, FACC a,Thomas Stefenelli MD, FACC a,Julia Niederberger MD a,... - 《Journal of the American College of Cardiolo...
However, and despite its importance, methods to measure the stiffness of the ascending aorta are limited. Objective: To introduce a method for calculating local PWV in the human ascending aorta using non-invasive ultrasound measurements of its diameter (D) and flow velocity (U). Approach: Ten ...

This requires not only the geometry of the aorta but also the nonlinear anisotropic properties of the tissue. In this study, we presented a methodology to estimate the mechanical properties of the aorta from magnetic resonance imaging (MRI). As a theoretical framework, we used finite element ...
