Aortic dilatation associates with flow displacement and increased circumferential wall shear stress in patients without aortic stenosis: A prospective clinical study

High prevelance of ascending aortic dilatation in a consecutive coronary CT angiography patient population

A smaller heart-aorta-angle associates with ascending aortic dilatation and increases wall shear stress

Pulmonary Artery Dilatation Is a Common Finding in a Coronary Artery CT Angiography Population

Excess of visceral adipose tissue with or without aortic elongation leads to a steeper  heart position

Wall Shear Stress Predicts Media Degeneration and Biomechanical Changes in Thoracic Aorta

Dilatation of the ascending aorta – Growth rate, risk factors and clinical outcomes in the long-term follow-up

Flow displacement and decreased wall shear stress might be associated with the growth rate of an ascending aortic dilatation
