نبذة مختصرة : Background: There is no consensus regarding the strategies for repairing acute type A aortic dissection (ATAAD) in patients with bicuspid aortic valve (BAV). This meta-analysis aimed to compare the treatment strategies and outcomes of ATAAD repair between patients with BAV and those with tricuspid aortic valve (TAV). Methods: A systematic review of databases were performed from inception through March 2023. The primary outcome of interest was all-cause mortality, with a minimum follow-up of 1 year. The secondary outcomes of interest included ratios of performed procedures and rate of distal aortic reoperation. Data were extracted, and pooled analysis was performed using a random-effects model. Results: Eight observational studies including a total of 3701 patients (BAV, n = 349; TAV, n = 3352) were selected for a meta-analysis. Concerning proximal aortic procedures, BAV patients exhibited a higher incidence of necessary root replacement (odds ratio [OR], 6.53; 95% confidence interval [CI], 3.84 to 11.09; P
