Flow angle | The angle of deviation from the center of the aortic lumen |
Flow displacement | The distance of flow jet deviation from the center of the aortic lumen indexed to ascending aortic diameter |
Rotational flow | The blood flow circling within the aortic plane |
WSScircavg | Circumferentially averaged systolic wall shear stress - surrogate marker for the friction the blood flow exerts onto the aortic wall |
In-plane wall shear stress | (the ‘rotational’ component) exerted by the blood circling within the plane along the aortic wall |
Through-plane wall shear stress | Exerted by the blood flowing through the vessel. |
