The patient-specific biomechanical analysis of the aorta requires the quantification of the in
vivo mechanical properties of individual patients. Current inverse approaches have …

Objective To test whether aneurysm biomechanical ratio (ABR; a dimensionless ratio of wall
stress and wall strength) can predict aneurysm related events. Methods In a prospective …

Accurate identification of in vivo nonlinear, anisotropic mechanical properties of the aortic
wall of individual patients remains to be one of the critical challenges in the field of …

Volumetric meshes with hexahedral elements are generally best for stress analysis using
finite element (FE) methods. With recent interests in finite element analysis (FEA) for …

The analysis of mechanobiology of arterial tissues remains an important topic of research for
cardiovascular pathologies evaluation. In the current state of the art, the gold standard to …

This study described the regional distribution of layer-specific residual deformations in
fifteen human aortas collected during autopsy. Circumferentially and axially cut strips of …

Ascending aortic aneurysms (AsAA) often include the dilatation of sinotubular junction (STJ)
and extend proximally into the aortic root, which usually leads to aortic insufficiency. The …

Background Abdominal aortic aneurysm (AAA) is a permanent and irreversible dilation of
the lower region of the aorta. It is typically an asymptomatic condition that if left untreated can …

The establishment of in vivo, noninvasive patient-specific, and regionally resolved
techniques to quantify aortic properties is key to improving clinical risk assessment and …

The aim of the present work is to propose a robust computational framework combining
computational fluid dynamics (CFD) and 4D flow MRI to predict the progressive changes in …
