5.4 Recommendations Recommendations for the management of aortic disease Recommendations Classa Levelb All aortic diseases It is recommended that women with aortic disease have counselling about the risk of aortic dissection.19,178 I C Imaging of the entire aorta (CT/MRI) is recommended before pregnancy in patients with a genetically proven aortic syndrome or known aortic disease.53 I C In bicuspid aortic valve patients, imaging of the ascending aorta is recommended before pregnancy. I C When a woman with known aortic dilatation (history of) dissection or genetic predisposition for dissection becomes pregnant, strict blood pressure control is recommended.185 I C Repeated echocardiographic imaging every 4–12 weeks (depending on diagnosis and severity of dilatation) is recommended during pregnancy and 6 months post-partum in patients with ascending aorta dilatation.194 I C For imaging of pregnant women with dilatation of the distal ascending aorta, aortic arch, or descending aorta, MRI (without gadolinium) is recommended.53 I C It is recommended to deliver all women with aortic dilatation or (history of) aortic dissection in an experienced centre with a pregnancy heart team, where cardiothoracic surgery is available. I C In patients with an ascending aorta <40 mm, vaginal delivery is recommended.96 I C In patients with an ascending aorta >45 mm, caesarean delivery should be considered. IIa C In patients with (history of) aortic dissection, caesarean delivery should be considered. IIa C Prophylactic surgery should be considered during pregnancy if the aorta diameter is >45 mm and increasing rapidly. IIa C When the foetus is viable, delivery before necessary surgery should be considered.96 IIa C In patients with an aorta 40–45 mm, vaginal delivery with epidural anaesthesia and an expedited second stage should be considered. IIa C In patients with an aorta 40–45 mm, caesarean section may be considered. IIb C Pregnancy is not recommended in patients with (or history of) aortic dissection. III C When possible, the use of ergometrine is not recommended in women with aortic disease. III C Specific syndromes In patients with vascular Ehlers–Danlos syndrome, celiprolol is recommended.186 I C Beta-blocker therapy throughout pregnancy should be considered in women with Marfan syndrome and other heritable thoracic aortic diseases. IIa C Pregnancy is not recommended in patients with severe dilatation of the aorta (heritable thoracic aortic disease such as Marfan syndrome >45 mm, bicuspid aortic valve >50 mm or >27 mm/m2 BSA, or Turner syndrome ASI >25 mm/m2 BSA).19,20 III C Pregnancy is not recommended in patients with vascular Ehlers–Danlos syndrome.26 III C ASI = aortic size index; BSA = body surface area; CT = computed tomography; MRI = magnetic resonance imaging. aClass of recommendation. bLevel of evidence.
