Disparities in outcomes for patients with cardiovascular disease and those undergoing cardiac or vascular operations are well-established. These disparities often span several dimensions and persist despite advancements in medical and surgical care; sex is among the most pervasive. Specifically, females sex has been implicated as a predictor of poor outcomes in both patients with acute type A aortic dissections (ATAADs) and type B aortic dissections (TBADs). For instance, one study, using the International Registry of Acute Aortic Dissection database, found that females with acute aortic dissection-including ATAAD and TBAD that were either medically or surgically managed-had 40% higher odds of in-hospital mortality than men. Notably, both types of acute aortic dissections affect men more commonly than females and can be life-threatening without prompt, appropriate treatment. The underlying mechanisms for these disparities are unclear but are thought to be multifactorial. The association of sex with patterns of disease and outcomes in patients with ATAAD or TBAD remains unclear, with conflicting reports from different studies. Thus, we sought to review the literature regarding sex disparities in patients with ATAAD and TBAD.
