Turner's syndrome
Pregnancy is possible in women with mosaic Turner syndrome or following assisted reproduction
techniques. Patients with Turner syndrome have an increased incidence of bicuspid aortic valve and
coarctation and the associated aortopathy. As women with Turner syndrome are of short stature, the
aortic size should be indexed to the body surface area. Patients with aortic dilatation >25 mm/m2 have
been found to have a 33% risk of aortic dissection in the absence of pregnancy [17], and they should be
considered for prophylactic aortic root replacement.
