Primary Outcome Measures:
  • Patients With Major Adverse Events (MAE) [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]

    Major adverse event is defined as:

    All-cause death; Q-wave MI; cardiac event involving arrest, resuscitation, or balloon pump; ventilation > 72 hours or re-intubation; pulmonary event requiring tracheostomy or chest tube; renal failure requiring permanent dialysis, hemofiltration, or kidney transplant in a patient with a normal pre-procedure serum creatinine level; bowel resection; stroke; paralysis; amputation involving more than toes; aneurysm or vessel leak requiring re-operation; deep vein thrombosis requiring surgical or lytic therapy; pulmonary embolism involving hemodynamic instability or surgery; coagulopathy requiring surgery; or wound complication requiring return to the operating room.

  • Patients With Device Failures [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Device failure is defined as: Technical failure (inability to access or deploy the Zenith® TX2® Low Profile TAA Endovascular Graft or loss of patency at the time of deployment completion), or any of the following: type I or type III endoleaks requiring re-intervention, aneurysm rupture or conversion to open surgical repair, aneurysm enlargement greater than 0.5 cm.
