Root Replacement Surgery Versus More Conservative Management During Type A Acute Aortic Dissection Repair

This study used data from the International Registry of Acute Aortic Dissection to explore the rates and outcomes of root replacement vs more conservative management in patients with acute type A dissections.  Root replacement patients were younger, had greater root diameter, were more often affected by Marfans, had a higher incidence of AI, and were more often affected by shock/hypotension/tamponade.  Root replacement had no detrimental affect on hospital mortality or 3-year survival.
