Changes in operative strategy for patients enrolled in the International Registry of Acute Aortic Dissection interventional cohort program

There have been significant changes in operative strategy over time in the management of type A aortic dissection, with more frequent use of valve-sparing procedures, bioprosthetic aortic valve substitutes, antegrade cerebral perfusion strategies, and hypothermic circulatory arrest. Most importantly, a significant decrease of in-hospital mortality was observed during the 20-year timespan.
