• The most inclusive category of early death: In-hospital death regardless of the

length of hospital stay In-hospital death includes any

death after transfer to another hospital or long term acute care facility

30-day death, including those rare deaths after discharge to home

Operative Mortality

• A composite endpoint• Comprised of:

Operative mortality

Permanent stroke Permanent paraplegia Permanent paraparesis Permanent renal failure

Adverse Event

Permanent = present at time of hospital discharge or early death

30-day or in-hospital death, including death after transfer

• Discharge of early survivors with a complication that negatively impacts quality of life and longevity

• Discharge with unresolved: Paraplegia Paraparesis Stroke Renal failure necessitating

dialysis

Freedom from Repair Failure

• Contemporary TAAA repair yields good-to-excellent outcomes in experienced centers

• Results are generally better in younger patients Patients with Marfan syndrome Survivors of DeBakey I dissection Extent I and II

• Long-term survival reasonable Patients are usually > 65 years and generally achieve

near life expectancy• Repairs are reliable

Few late events or secondary reinterventions
