Annulo-aortic ectasia

Dr Yair Glick and Dr Azza Elgendy et al.

Annulo-aortic ectasia refers to a proximal dilatation of the aortic root at the level of the aortic annulus, it is also the same level as the sinus of Valsalva.


Annulo-aortic ectasia occurs with connective tissue diseases such as Marfan disease and Ehlers-Danlos syndrome. It is a cystic medial necrosis, which puts the patients at great risk for aortic dissection, which in turn may lead to rupture 1-3.
