NON-SURGICAL MANAGEMENT OF TYPE A ACUTE AORTIC DISSECTION: INSIGHTS FROM THE INTERNATIONAL REGISTRY OF ACUTE AORTIC DISSECTION (IRAD)

Results: Reasons for NS management included: prohibitive comorbidities 151 (59.0%), advanced age 69 ( 27.0%, average age 81.0±7.0), patient preference 37 (14.5%) , and intramural hematoma of arch or descending aorta 26 (10.0%) and 12 (4.7%, respectively). In-hospital mortality was higher for NS (56.3% vs. 21.5%, p < 0.001). Data was separated into tertiles based on time of incident dissection. The % of NS patients and inhospital mortality of all TA-AAD patients decreased over this time span (Table).
