Background:
The influence of sex on outcomes of surgery for acute type A aortic dissection remains incompletely characterized. We sought to evaluate post-procedural survival in the follow-up of females versus males.
Methods:
We carried out a systematic review with meta-analysis of Kaplan-Meier-derived time-to-event data from studies published by June 2023 in the following databases: PubMed/MEDLINE, EMBASE, Web of Science and CENTRAL/CCTR (Cochrane Controlled Trials Register).
Results:
Twelve studies met our eligibility criteria, including 11,696 patients (3753 females; 7943 males). The mean age ranged from 41.2 to 72.6 years with low prevalence of bicuspid aortic valve (ranging from 0.0% to 12.0%) and connective tissue disorders (ranging from 0.8% to 7.3%). We found a considerable prevalence of coronary artery disease (ranging from 12.1% to 21.1%) and malperfusion (ranging from 20.0% to 46.3%). At 10 years, females undergoing surgery had a significantly higher risk of all-cause mortality compared with males (HR 1.25, 95%CI 1.14-1.38, P < 0.001).
Conclusion:
In the follow-up of patients undergoing surgery for type A aortic dissection, females presented poorer overall survival in comparison with males.
