Abstract

Background: Outcomes of early-onset acute type A aortic dissection (ATAAD) associated with Marfan syndrome (MFS) are known, but not with other etiologies. Methods and Results: ATAAD patients from 2 centers (n=1,001) were divided into 2 groups: age ≤45 years (n=93) and age >45 years (n=908). Although in-hospital death and 10-year survival were similar (12% vs. 7% and 62.6% vs. 67.3%), the 10-year aortic event-free survival differed (50.0% vs. 80.2%; P<0.01). ATAAD patients from 3 centers (n=132), all aged ≤45 years, were divided into 5 groups: lone hypertension (HTN, n=71), MFS (n=23), non-syndromic familial thoracic aortic aneurysm and dissection (NS-FTAAD, n=16), bicuspid aortic valve (BAV, n=11), and no known etiologic factor (n=11). The incidence of severe aortic insufficiency varied between groups (HTN: 11%, MFS: 39%, NS-FTAAD: 38%, BAV: 55%, no known factor: 46%; P<0.01), whereas in-hospital death did not (14%, 22%, 0%, 0%, and 9%; P=0.061). The 10-year survival was 52.2%, 64.7%, 83.6%, 100%, and 90.9%, respectively, and 10-year aortic event-free survival was 55.6%, 36.3%, 77.5%, 90.0%, and 30.0%. Median descending aorta growth (mm/year) was 1.1 (0.1-3.4), 2.3 (0.3-5.3), 1.9 (1.3-2.7), 0.9 (-0.1-2.0), and 1.0 (-0.2-2.9) (P=0.15), respectively.

Conclusions: Late aortic events are common in young ATAAD patients. Known etiologic factors, though not BAV, negatively influence late outcomes in these patients.
