The study will evaluate three-dimensional (3D) imaging data, both at baseline and through follow-up. Baseline 3D anatomy will augment information on the precise anatomic configuration of patients presenting aortic arch pathology treatable with the device. Follow-up imaging will provide information on the effectiveness of the device with respect to endoleaks in patients with aneurysms, sealing of dissections, PAU and IMH, and stability of the device at the deployed position, response, endograft patency, and short-term device integrity.
