Inclusion criteria

* Subject is ≥18 years old * Subject was treated in the last 7 days, or is intended to be treated, with the Valiant Navion Thoracic Stent Graft System for a dissection in the thoracic aorta * Subject is willing to comply with standard of care clinical follow-up * Subject or legal representative or consultee, as applicable has consented for study participation and signed the approved Informed Consent

Exclusion criteria

* Subject is participating in an investigational drug or device study which may bias or interfere with the endpoints and follow-up of this study. * Subject is pregnant (not an exclusion if allowed per local regulatory requirements, pregnancy test to be performed where required) * Subject has an active COVID-19 infection or relevant history of COVID-19. Relevant history of COVID-19 is defined as availability of a positive COVID-19 test with sequela or hospitalization for treatment of COVID-19. Subjects with a positive COVID-19 test who were asymptomatic or had mild symptoms should be excluded only if the positive test was less than 3 months prior to enrollment.

Design outcomes

Primary

MeasureTime frameDescription
Composite safety and effectiveness1-month post index procedureSafety: Major Adverse Events (MAEs) Defined as: all-cause mortality (ACM), retrograde type A dissection (RTAD), aortic rupture, permanent paraplegia and paraparesis, stent induced new entry tear, conversion to open repair, disabling stroke, and non-preexisting renal failure. Effectiveness: Technical success defined as ability to advance, deploy and position the Valiant Navion Thoracic Stent Graft at target site with successful coverage and sealing of the proximal entry tear and removal of the delivery system. The primary endpoint is a dichotomous study outcome and a composite endpoint. A subject who has technical success and no MAE reported within 1-month will be considered a success.

Secondary

MeasureTime frameDescription
Aortic remodeling1-month, 1, 2 and 3 yearsRate of aortic remodeling based on follow-up imaging.
Access related complicationsperi-operativeRate of access related complications as proportion of evaluable patients.
Stent induced entry tear1, 2 and 3 yearsRate of stent induced entry tear as proportion of evaluable patients.
Stent graft migration1, 2 and 3 yearsRate of stent graft migration (\>10mm) as proportion of evaluable patients.
Stent graft integrity1-month, 1, 2 and 3 yearsRate of each type of loss of stent graft integrity (kink, twist, fracture, occlusion, or stenosis) as a proportion of evaluable patients based on follow-up imaging.
Disease progression1,2 and 3 yearsExtension of dissection.
Transient Ischemic Attack (TIA)/minor strokes1-monthRate of TIA/minor stroke as a proportion of evaluable patients.
Transient spinal cord ischemia1-month, 1, 2 and 3 yearsRate of transient spinal cord ischemia as a proportion of evaluable patients.
Unplanned secondary procedures1, 2 and 3 yearsRate of unplanned secondary procedures.
False lumen perfusion1-month, 1, 2 and 3 yearsRate of each type of false lumen perfusion based on follow-up imaging.
Endoleaks1-month, 1, 2 and 3 yearsRate of each type of endoleak based on follow-up imaging.
Major adverse events1, 2 and 3 yearsMajor adverse events defined as: * All-cause mortality (ACM) * Retrograde type A dissection (RTAD) * Aortic rupture * Permanent paraplegia and paraparesis * Stent induced new entry tear * Conversation to open repair * Disabling stroke * Non-preexisting renal failure
