OBJECTIVES: Type B aortic dissection (TBAD) is rare in patients aged ≤30 years, and data on this population remain limited. This study aimed to characterize the underlying aetiology, and outcomes of invasively treated young patients with TBAD, with a focus on the impact of heritable thoracic aortic disease (HTAD).
METHODS: A retrospective multicentre analysis was conducted across 19 international aortic centres, including 139 patients aged ≤30 years with TBAD. Patients with chronic TBAD (n = 42) were excluded for the final analysis. The cohort was classified as uncomplicated (n = 86) or complicated (n = 53) TBAD. Clinical, radiologic, intraoperative, and postoperative data were collected using standardized forms. Outcomes were compared between subgroups defined by TBAD complexity, HTAD status, and surgical strategy. Kaplan-Meier and Andersen-Gill analyses were used for survival and recurrent aortic intervention, respectively.
RESULTS: Mean follow-up time was 6.5 years. HTAD was identified in 57% of patients. Most presented with uncomplicated TBAD (62%), while high-risk uncomplicated cases were uncommon. Endovascular repair was predominant in complicated TBAD, while open repair was more frequent in uncomplicated cases. Early mortality was low (n = 3), and mid-term survival was excellent across all subgroups. HTAD was a significant predictor of recurrent aortic interventions (HR = 3.3, P = .004). No significant differences were observed in survival or reintervention rates between uncomplicated and complicated TBAD or between operative strategies.
CONCLUSIONS: In young patients, TBAD predominantly occurs in the context of HTAD. Both open and endovascular repair are associated with excellent early outcomes and mid-term survival. However, HTAD remains a significant predictor of recurrent aortic interventions.
