Key result
Type A aortic dissection in-hospital mortality falls ~29% over 17 years, with type B unchanged.
Why the study?
Diagnosis, treatment, and outcomes of acute aortic dissection are changing, necessitating examination of trends in presentation, diagnosis, and hospital outcomes over time.

Over a 17-year period, in-hospital mortality for type A acute aortic dissection decreased significantly alongside increased surgical management, whereas type B mortality remained unchanged despite increased endovascular management.
Pape et al. (2015) conducted an observational in Acute Aortic Dissection (n=4,428). Later enrollment period (17-year trend) vs. Earlier enrollment period was evaluated on Type A in-hospital mortality (p=<0.001). Over a 17-year period, in-hospital mortality for type A acute aortic dissection decreased significantly from 31% to 22% (P<0.001), while type B mortality remained unchanged.
