N2 - OBJECTIVES: The Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) is a collaborative effort of Nordic cardiac surgery centers to study acute type A aortic dissection (ATAAD). Here, we outline the overall objectives and the design of NORCAAD.DESIGN: NORCAAD currently consists of eight centers in Denmark, Finland, Iceland and Sweden. Data was collected for patients undergoing surgery for ATAAD from 2005 to 2014. A total of 194 variables were retrospectively collected including demographics, past medical history, preoperative medications, symptoms at presentation, operative variables, complications, bleeding and blood transfusions, need for late reoperations, 30-day mortality and long-term survival.RESULTS: Information was gathered in the database for 1159 patients, of which 67.6% were male. The mean age was 61.5 ± 12.1 years. The mean follow-up was 3.1 ± 2.9 years with a total of 3535 patient years.CONCLUSIONS: NORCAAD provides a foundation for close collaboration between cardiac surgery centers in the Nordic countries. Substudies in progress include: short-term outcomes, long-term survival, time interval from diagnosis until operation, effects of surgical techniques, malperfusion syndrome, renal failure, bleeding and neurological complications on outcomes and the rate of late reoperations.
