TL;DR: Encouragingly, a positive correlation was observed between degree of stenosis and mid-ascending size (p=0.016) and this could suggest that surgical approach may spare the root in most BAV patients, suggesting a post-stenotic causative mechanism.

TL;DR: In patients with BAV, the root phenotype may be a marker of more severe aortopathy, warranting closer surveillance and earlier treatment, and the more common ascending phenotype proved to be a more stable disease entity, generally with slower progression.

TL;DR: Although with still considerable early mortality, endovascular stent-graft implantation is an effective option for the treatment of complicated type B aortic dissection, even in patients with worse preoperative conditions.

TL;DR: When tested on a large population, three previously suggested phenotypic classifications of the BAV aorta proved to categorize patients into significantly different clusters, but only the classification system distinguishing between ascending phenotype and root phenotype showed a potential prognostic value.

TL;DR: The two most common BAV morphotypes are associated with aortic dilatation at two different tracts (RL at the root; RN at the tubular ascending tract) independently of valve function.
