NCT01114724
First received: April 26, 2010
Last updated: January 30, 2014
Last verified: January 2014
  Purpose

The purpose of this study is to determine if the Valiant stent graft is safe and effective in treating patients who have a thoracic dissection. A thoracic dissection is a tear in the wall of the aorta, that causes blood to flow between the layers of the aorta and force the layers apart(dissect). This condition is a medical emergency and can quickly lead to death. Since stent grafting has been an effective way to treat other aortic conditions such as aneurysms (bulge in aorta wall), it is believed that the device would be effective in treating dissections. Information will be collected on the performance of the device for 5 years.

Primary Outcome Measures:
  • All cause mortality. [ Time Frame: Up to 30 days after the stent graft implant. ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Successful delivery and deployment of the device. [ Time Frame: At time of implant. ] [ Designated as safety issue: Yes ]
  • Change in the aorta. [ Time Frame: At 6 and 12 months. ] [ Designated as safety issue: Yes ]
  • The device covers the tear in the aorta. [ Time Frame: At implant through 60 months. ] [ Designated as safety issue: Yes ]
  • Secondary aortic repair [ Time Frame: Up to 60 months after the implant. ] [ Designated as safety issue: Yes ]
  • Device, procedure and/or aortic related serious adverse events. [ Time Frame: Up to 60 months after the implant. ] [ Designated as safety issue: Yes ]

Criteria

Inclusion Criteria:

  • Subject has an acute, complicated Type B aortic dissection with evidence of at least one of the following:
  • Malperfusion (visceral, renal, spinal cord and/or lower limb ischemia).
  • Rupture.
  • Subject's anatomy must meet the anatomical criteria to receive that implanted device.

Exclusion Criteria:

  • Subject has a history of bleeding diathesis, coagulopathy, or refuses blood transfusion.
  • Subject has a history of Marfan Syndrome or other connective tissue disorder.
  • Subject has a known allergy or intolerance to the device components.
  • Subject has a known hypersensitivity or contraindication to anticoagulants or contrast media, which is not amenable to pre-treatment.
  • Subject has a co-morbidity causing expected survival to be less than 1 year.
