IRAD is evaluating the current management and outcomes of acute aortic dissection. It was established in 1996. The main purpose of IRAD is to assess the etiological factors, modes of presentation, clinical features, treatment, and hospital outcomes of patients with acute aortic dissection around the world. Creation of working groups to identify new breakthroughs in diagnosis and treatment have just been developed including groups targeting: the genetic basis of aortic dissection; use of acute and chronic biomarkers; best surgical approach; best medical approach; how patients should be followed; and what is the proper role for percutaneous stent graft therapy. The University of Michigan Health System is the Coordinating Center.
