Aortic Dilatation and Dissection in Turner Syndrome

Abstract

The risk for aortic dissection is greatly increased in young women with TS. Because of their small stature, ascending aortic diameters of < 5 cm may represent significant dilatation; thus, the use of aortic size index is preferred. Individuals with a dilated ascending aorta defined as aortic size index > 2.0 cm/m2 require close cardiovascular surveillance. Those with aortic size index > or = 2.5 cm/m2 are at highest risk for aortic dissection.
