Flow Displacement and Wall Shear Stress in Individuals with Mild-to-Moderate Aortic Dilation and Tricuspid Aortic Valves

Altered hemodynamics may play a role in the development of ascending aortic aneurysms. In this study, we sought to investigate wall shear stress and flow displacement in patients with tricuspid aortic valve and mild-to-moderate dilatation of the ascending aorta, and age-and sex- matched non-dilated controls. Dilated patients had lower average velocity and wall shear stress in the ascending aorta, and higher flow displacement. This study shows that individuals with dilatation have altered hemodynamics even in an early stage of the disease.
