Primary Outcome Measures:
  • Disease-, procedure- or device-related mortality at 12 months post-procedure [ Time Frame: 12 months post-procedure ] [ Designated as safety issue: No ]
    Disease, device or procedure-related mortality at 12 months post-procedure, defined as any death related to the device, to the disease or to the surgical procedure occurring in the period of 365 days following the day of the implant procedure.


Secondary Outcome Measures:
  • Health Economics [ Time Frame: Up to 6 months post-procedure ] [ Designated as safety issue: No ]
    Hospital and staff resources associated with the procedure and treatment up to six months post-procedure.

  • Safety [ Time Frame: 30 days or at discharge, 3/6/12/24/36 months ] [ Designated as safety issue: Yes ]
    • All causes mortality
    • Disease-, procedure- or device-related mortality

  • Efficacy/Performance [ Time Frame: 30 days or at discharge, 3/6/12/24/36 months ] [ Designated as safety issue: Yes ]
    • Technical Success
    • Freedom of re-intervention
    • Freedom of disease-, stent- or procedure-related severe complications
    • Freedom of disease-, stent- or procedure-related major complications
    • Freedom of re-intervention and disease-, stent- or procedure-related severe complications
    • Clinical Success
    • Clinical Success and freedom of severe disease-, stent- or procedure-related complications
    • Clinical Success and freedom of disease-, stent- or procedure-related major complications

Groups/Cohorts
Descending thoracic aortic dissection
Patients diagnosed with a descending thoracic aortic dissection and who are amenable to stent-graft operation. The patient had an indication for treatment by either endovascular stent graft implantation for either an acute, sub-acute or chronic Type B dissection.

Detailed Description:

The patient device for use in this registry is the Medtronic VALIANT Thoracic Stent Graft System that received CE mark approval in March 2005.

The Medtronic VALIANT Thoracic Stent Graft with Xcelerant Delivery System is designed to treat diseases of the descending thoracic aorta including but not limited to aneurysms and dissections. The VALIANT Stent Graft is designed to exclude the aneurysm, the false lumen or site of rupture and restore the blood flow through the stent graft lumen. The device is intended for use either in patients who are candidates for conventional surgical repair, and in patients who are not candidates for conventional surgical repair due to pre-existing risk factors.

This registry is a prospective, non-randomized, single-arm, multi-center, European clinical registry with patients diagnosed with descending thoracic aortic dissection.

For this registry standard hospital procedures with respect to patient interventional care for thoracic aortic diseases will be followed.

This is a descriptive registry in which no specific hypotheses will be statistically tested.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Patients diagnosed with a descending thoracic aortic dissection and who are amenable to stent-graft operation will be enrolled in the registry.

Criteria

Inclusion Criteria:

  • Patient will be more than or equal to 18 years of age; or older if required by local regulations.
  • Patient has an indication for treatment by either endovascular stent graft implantation for either an acute, sub-acute or chronic Type B dissection.
  • Patient is amenable for stent-graft treatment (in accordance with the IFU).
  • The patient is willing and able to cooperate with registry procedures and required follow-up visits.
  • The patient or legal guardian has signed a patient informed consent form, including data privacy authorization (this criteria is not applicable for patients presenting in emergency with ruptured dissection and for whom legal representative is not available informed consent can be requested after surgical procedure).

Exclusion Criteria:

  • Patients with a thoracic dissection for which optimal treatment is observation and medical management.
  • Patient with current - non aortic - medical condition with a life expectancy less than one year.
  • The patient is participating in another device or drug study (patient must have completed the follow-up phase of any previous study at least 30 days prior to enrolment in this registry).
  • Time interval between medical indication for surgical intervention and endovascular procedure exceeds 4 months (122 days).
