Brief Summary

Thoracic endovascular aortic repair (TEVAR) for disease involving the aortic arch remains complex and challenging due the angulation and tortuosity of the arch and its peculiar biomechanical environment. Currently, TEVAR planning is based on the analysis of anatomical features by means of static imaging protocols. Such an approach, however, disregards the impact of pulsatile forces that are transmitted as migration forces on the terminal fixation sites of the endograft, and may jeopardize the long-term clinical success of the procedure. Hence,the investigators aim to assess the migration forces acting on different proximal landing zones of the aortic arch by computational modeling, and develop in silico patient-specific simulations that can provide a quantitative evaluation of the stent-graft performance. Study's results are expected to provide valuable insights for proper proximal landing zone and stent-graft selection during TEVAR planning, and ultimately improve postoperative outcome.

patients scheduled for thoracic endovascular aortic repair

Diagnostic Test: TEVAR patients

Interventions

TEVAR patientsDIAGNOSTIC_TEST

Computed Tomography Angiography (CTA) will be performed using a 16-slice unit before and after intravenous administration of 100 mL of iodinated contrast material. Phase contrast-Magnetic Resonance (pc-MRI) will be performed using a 1.5-T unit with 40-mT/m gradient power and a four-channel cardio-thoracic coil. ECG-triggered, free-breathing through plane, and in-plane pc-MRI sequences will be performed for phase-velocity mapping of aortic and branches flow. Ad hoc processing of preoperative CTAs, based on 3D multiplanar reconstruction, will be performed with 3Mensio Vascular software 8.0® (3Mensio Medical Imaging B.V.), which provides specific functions for automatic measurements.
