Delay from Diagnosis to Surgery in Transferred Type A Aortic Dissection

The purpose of this research is to analyze factors associated with delays to surgical management of Type A acute aortic dissection patients. Time from diagnosis to surgery and associated factors were evaluated in 1880 surgically managed Type A dissection patients enrolled in the International Registry of Acute Aortic Dissection. The majority of patients were transferred (75.7% vs 24.3%). Patients who were transferred had a median delay from diagnosis to surgery of 4.0 hours (interquartile range 2.5-7.2 hours), compared with 2.3 hours (interquartile range 1.1-4.2 hours; P
