Hemodynamic factors, induced by pulsatile blood flow, play a crucial role in vascular health
and diseases, such as the initiation and progression of atherosclerosis. Computational fluid …

Background: Ascending thoracic aortic aneurysm is a chronic degenerative pathology
characterized by dilatation of this segment of the aorta. Clinical guidelines use aortic …

Aims Increasing aortic dilation increases the risk of aortic dissection. Nevertheless,
dissection occurs at dimensions below guideline-directed cut-offs for prophylactic surgery …

OBJECTIVES Rapid diameter growth is a criterion for ascending thoracic aortic aneurysm
repair; however, there are sparse data on aneurysm elongation rate. The purpose of this …

Diameter-based criterion have been widely adopted for preventive surgery of ascending
thoracic aortic aneurysm (ATAA). However, recent and growing evidence has shown that …

Background Patients with ascending thoracic aortic aneurysm are recommended to undergo
routine imaging surveillance. Although maximal diameter is the primary metric of disease …

We propose a new approach for constructing strain-based rupture criterion for ascending
thoracic aortic aneurysm. The rupture metric is formulated using an effective strain, which is …

Background In ascending thoracic aortic aneurysm risk stratification, aortic area/height ratio
is a reasonable alternative to maximum diameter. Biomechanically, aortic dissection may be …

Risk of aortic dissection in ascending thoracic aortic aneurysms is not sufficiently captured
by size-based metrics. From a biomechanical perspective, dissection may be initiated when …

Purpose Finite element analysis (FEA) has been used to predict wall stress in ascending
thoracic aortic aneurysm (ATAA) in order to evaluate risk of dissection or rupture. Patient …
