Three-dimensional characterization of ascending aortic strain, motion and growth in patients undergoing thoracic endovascular aortic repair.

ABSTRACT:

Objective

We utilized vascular deformation mapping (VDM) to assess ascending aortic motion, regional stiffness and growth in patients who underwent zone 2/3 thoracic endovascular aortic repair (TEVAR) to quantify changes in ascending aorta biomechanics after endograft implantation.

Methods

Multi-planar, multi-directional aortic motion, aortic strain, and three-dimensional aortic growth was extracted by VDM from electrocardiography-gated computed tomography angiograms. Aortic displacement and strain were compared between patients who underwent TEVAR (both pre- and post-procedure) and in patients with dilated ascending aorta (>4.0 cm) and a non-dilated control group.

Results

One hundred twenty subjects were included for analysis. Between pre-TEVAR and post-TEVAR, total
