Background: Acute type B aortic dissection (TBAD) is a severe condition associated with significant morbidity and mortality. The optimal classification and treatment strategy of TBAD remain controversial and inconsistent.
Methods: This analysis includes patients treated for acute TBAD at the Helsinki University Hospital, Finland between 2007 and 2019. The endpoints were early and late mortality, intervention of the aorta, and a composite of death and aortic intervention in uncomplicated patients and high-risk patients.
Results: This study included 162 consecutive TBAD patients (27.8% females), 114 in the high-risk group and 48 in the uncomplicated group, with a mean age of 67.6 ± 13.9 years. Intramural hematoma was reported in 63 cases (38.9%). The mean follow-up was 5.1 ± 3.9 years. In-hospital/30-day mortality (n = 4; 3.5%) occurred solely in the high-risk group (P = 0.32). Additionally, TBAD-related adverse events (n = 23; 20.2%) were observed only in the high-risk group (P < 0.001). The cumulative incidences of the composite TBAD outcome with non–TBAD-related death as a competing risk were 6.6% (95% CI, 1.7%–16.5%) in the uncomplicated group and 29.5% (95% CI, 21.1%–38.3%) in the high-risk group at 5 years and 6.6% (95% CI, 1.7%–16.5%) and 33.0% (95% CI, 23.7%–42.6%) at 10 years (P = 0.001, Gray test). Extracardiac arteriopathy (subdistribution hazard ratio [SHR], 2.61; 95% CI, 1.08–6.27) and coronary artery disease (SHR, 2.24; 95% CI, 1.07–4.71) were risk factors for adverse aortic-related events in univariable competing-risk regression analysis.
Conclusions: Recognition of risk factors underlying adverse events related to TBAD is essential because the disease progression impacts both early and late outcomes. Early aortic repair in high-risk TBAD may reduce long-term morbidity and mortality.
