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

In type A acute aortic dissection patients more-extensive RR interventions are not associated with increased hospital mortality. This supports such an approach in young patients and patients with connective tissue diseases and bicuspid aortic valves. Excellent midterm survival and freedom from root reintervention in both groups suggest stable behavior of the nonreplaced aortic sinuses at 3 years. Thus, pending studies with longer follow-up, the use of aggressive RR techniques can be determined by patient-specific and dissection-related factors.
