Multiaxial pulsatile dynamics of the thoracic aorta and impact of thoracic endovascular repair

•Altered motion of the thoracic aorta after thoracic endovascular aortic repair.•Geometric analysis with cardiac-gated computed tomography and computer modeling.•Decreased motion of the stented aorta and increased motion above the stented aorta.•Longitudinal curvature and diametric deformation affected by presence of endograft.
