annuloaortic ectasia
Pronunciation: an-YOU-low-ay-OR-tick ek-TAY-zee-ah
Combined dilatation of the aortic annulus and ascending aorta without discrete aneurysm formation.
Full Definition
Annuloaortic ectasia describes a pathological condition characterized by diffuse dilatation of both the aortic valve annulus and the ascending aorta, typically manifesting as a smooth, symmetric enlargement without discrete aneurysm formation. This condition commonly occurs in patients with connective tissue disorders such as Marfan syndrome or as part of degenerative aortic disease. The progressive nature of annuloaortic ectasia often leads to aortic regurgitation and may require complex surgical intervention involving both valve and ascending aortic replacement.
Usage
Usage note: Often associated with connective tissue disorders; distinguish from discrete aneurysm formation.
