MeasureTime frameDescription
Patients With Major Adverse Events (MAE)30 daysMajor 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 Failures12 monthsDevice 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.
