Introduction: Data about proximal aortic reoperation after Type A dissection are mostly based on single center experience. We aimed to investigate the fate of proximal aorta after Type A dissection, utilizing a large international multicenter registry.

Methods: Data were extracted from an observational, multicenter, retrospective cohort study including 3902 patients who underwent surgery for TAAD at 18 tertiary hospitals. A total of 115 patients underwent a reoperation at the level if the proximal aorta. Freedom from reoperation was estimated with cumulative incidence survival and Fine-Gray competing risk regression model was used to identify independent risk factors for reoperation.

Results: Patients who had a proximal reoperation were younger (57 years vs 65 years, p<0.01), had higher incidence of Marfan syndrome (5.2% vs 1.8%, p 0.02). The median follow-up was 2.2 years (range, 0-17 years). Incidence of proximal reoperation at 5, 10 and 15 years was 2.9%, 4.4% and 6.5% respectively. Age, extension of the dissection in the left coronary were associated with proximal reoperation.

Conclusion: Type A aortic dissection repair was associated with a low proximal reoperation rate. Age and extension of the dissection were associated with reoperation.
