Aortic surgery in pregnancy.

Pregnancy engenders changes in hemodynamics and the aortic wall that make a woman more susceptible to aortic dilatation and dissection. This is particularly true of women with aortic dilatation and an aortopathy, including the inherited fibrillinopathies, bicuspid aortic valve, and Turner syndrome. Women in these risk groups may be served best by undergoing elective aortic surgery before becoming pregnant. However, some women present during pregnancy with significant aortic dilatation, rapid expansion, or aortic dissection, and strategies to deal with these situations, while optimizing maternal and fetal outcomes, change as gestation progresses. This review summarizes the approaches to the management of aortic diseases and the conduct of aortic surgery in pregnancy.
