Key result
R-N and R-L bicuspid aortic valves arise from distinct morphogenetic defects during outflow tract development.
Why the study?
It was uncertain whether bicuspid aortic valves with fused right and noncoronary leaflets and those with fused right and left leaflets have different etiologies or arise from a single diathesis.
No takes yet. Share an insight, caveat, or question.
Does not alter BAV management; leaves open whether subtype-specific etiologies warrant distinct human risk stratification.
Fernández et al. (2009) studied Bicuspid aortic valves. Bicuspid aortic valve subtypes (R-N vs R-L) was evaluated on Morphogenetic and etiological differences. R-N and R-L bicuspid aortic valves are distinct etiological entities resulting from different morphogenetic defects during cardiac outflow tract development.
