In women with a dilated aorta, delivery should occur in a tertiary care center where experienced cardiothoracic surgical expertise is available. Valvular Heart Disease (see also Chapter 67) Aortic Stenosis (see also Chapter 68) Aortic stenosis in women of childbearing age is usually secondary to a bicuspid aortic valve. In low- income countries, aortic stenosis may be secondary to rheumatic heart disease. A detailed echocardiographic assessment of the valve function should be performed before pregnancy is contemplated. A stress test can be useful to assess functional capacity and blood pressure response to 2 exercise. Women with severe aortic stenosis (a valve area < 1 cm or a mean gradient > 40 mm Hg) need careful preconception risk stratification by a cardiologist with expertise in pregnancy and heart disease. Some women with severe aortic stenosis who have an excellent functional capacity and a normal blood pressure response to exercise will be able to tolerate pregnancy. In addition, a careful examination of the entire thoracic aorta is indicated to look for bicuspid valve associated aortopathy; even with a functionally normal valve, an aortic dilation or ascending aortic aneurysm may be present. Surgical repair prior to pregnancy should be considered if the aorta is larger than 5 cm. Mild and moderate aortic stenosis is usually well tolerated if the patient has a normal exercise capacity and no symptoms. Pregnancy in women with severe aortic stenosis is characterized by an increased incidence of heart failure, arrhythmias, premature labor, and shorter pregnancy duration. In one study of 96 pregnancies in women with at least moderate aortic stenosis, 21% of women were hospitalized for 34 cardiac reasons during pregnancy. Although maternal mortality rates are very low in contemporary series, death has been reported in this group of women. Labor and delivery can be particularly problematic in such patients because of the abrupt hemodynamic changes, including immediately postpartum when there is an abrupt fall in afterload as the baby is delivered. Epidural analgesia needs to be carefully and slowly administered, and spinal block should be avoided because of the potential for hypotension. Delivery may be facilitated by arterial lines or central venous pressure monitoring, which should be continued for at least 24 hours after delivery. Over the long term, women with moderate or severe aortic stenosis who have been pregnant are more likely to require cardiac 35 interventions when compared with women who have not been pregnant. Mitral Stenosis (see also Chapter 69) Mitral stenosis is almost always due to rheumatic heart disease, and cardiac complications during pregnancy are common. Syndromes

Thoracoabdominal aortic aneurysm (approximately 10%) refers to descending thoracic aneurysms that extend distally to involve the abdominal aorta. Many of the genetic disorders preferentially involve the aortic root and ascending aorta, but some may involve the arch and descending aorta. These changes lead to progressive weakening of the aortic wall and may result in dilation and aneurysm formation. Genetically Triggered Thoracic Aortic Aneurysm Disorders Many disorders of the thoracic aorta are related to a genetic or heritable disorder, some of which are associated with multisystem syndromic features and others with thoracic aortic disease and branch vessel 12 disease alone (nonsyndromic) (Table 63. The phenotype in certain conditions may be subtle, and 13 intrafamilial variability is common, highlighting the importance of a careful physical examination. Such disorders include Marfan syndrome, Loeys-Dietz syndrome, vascular Ehlers- Danlos syndrome, familial thoracic aortic aneurysm and dissection syndrome, bicuspid aortic valve disease, Turner syndrome, and the aortopathy associated with many congenital heart diseases. The timing of prophylactic surgery for aneurysm disease in patients with these conditions depends on the gene defect and other factors, including aortic diameter, rate of aortic growth, family history, age, sex, and patient and 12 physician preferences (Table 63. Age, body size, rapid growth, family history, risk of surgery, and patient and physician wishes may influence aortic size threshold. Other risk factors for aortic dissection include coarctation of the aorta, hypertension, and the root phenotype of bicuspid aortic valve. If pregnancy desired, consider prophylactic aortic surgery for aortic diameter of 4. Aortic surgery at smaller diameters may be recommended when there are severe craniofacial features, rapid growth, or a family history of aortic dissection. Surgery for aortic dilatation in patients with bicuspid aortic valves: a statement of clarification from the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines. However, in randomized trials, there was no significant difference in rate of aortic 14,15 dilation in Marfan patients treated with atenolol or losartan (eFig. In the Dutch Marfan trial comparing the addition of losartan to standard care (using beta blocker in >70%), losartan therapy did 1,16 reduce aortic growth rate. An upcoming meta-analysis will explore subsets of patients 14,15 who may benefit from a specific treatment. The dilation is most pronounced in the sinuses of Valsalva, and the aorta narrows above the sinotubular junction.
