Objective To evaluate the benefits of surgical repair acute type A aortic dissection(ATAAD)on survival of octogenarians.Methods Patients who underwent surgery for acute ATAAD from the multicenter European Registry of Type A Aortic Dissection(ERTAAD)were the subjects of the present analysis.Results 326(8.4%)patients were aged≥80 years.Among 280 propensity score matched pairs,in-hospital mortality was 30.0%in patients aged≥80 years and 20.0%in younger patients(P=0.006),while 10-year mortality were 93.2%and 48.0%,respectively(P<0.001).The hazard of mortality was higher among octogenarians up to two years after surgery,but it became comparable to that of younger patients up to 5 years.Among patients who survived 3 months after surgery,10-year relative survival was 0.77 in patients aged<80 years,and 0.46 in patients aged≥80 years.Relative survival of octogenarians decreased markedly 5 years after surgery.Age≥85 years,glomerular filtration rate,preoperative invasive ventilation,preoperative mesenteric mal-perfusion and aortic root replacement were independent predictors of in-hospital mortality among octogenarians(AUC=0.792;E:O ratio=0.991;CITL=0.016;slope=1.096).An additive score was developed.A risk score≤1 was observed in 68.4%of patients,and their in-hospital mortality was 20.9%.Conclusions Provided a thoughtful patient selection,surgery may provide a survival benefit in patients aged≥80 years with ATAAD that,when compared to younger patients and the general population,may last up to 5 years after the procedure.These findings have significant epidemiologic and clinical relevance because of the increasing longevity of the population of the Western countries.
