Abstract
The aortic arch is the curved part of the aorta that follows the ascending aorta, which is connected to the left ventricle. The centerline of the thoracic part of the aorta, particularly of the arch, does not lie in a plane (non-planar), and is distorted in three dimensions (3D). Clinical magnetic resonance imaging (MRI) studies have shown that the flow in the aortic arch forms a single right-handed helix (Kilner 1993). This helical flow is thought to be responsible for the development of aneurysms, which are frequently found on the arch. The 3D configuration of the arch is thought to affect all of these phenomena.
