Pregnancy in Takayasu Arteritis: A Case Report of Successful Pregnancy in a Large Aortic Aneurysm

A 29-year-old primigravida woman with a gestational age of 19 weeks visited in the cardio-obstetrics clinic for hypertension. Physical examination revealed auscultated systolic and diastolic murmurs in the second right intercostal space. Transthoracic echocardiography (TTE) showed severe left ventricle (LV) enlargement with mild systolic dysfunction. Severe aortic regurgitation (AR) and aneurysmal dilation of the proximal part of the ascending aorta were noted. Magnetic resonance imaging (MRI) without contrast showed a dilated aortic root and ascending aorta (64.4 mm at the right pulmonary artery level). Imaging and serologic findings were compatible with acute Takayasu arteritis. Despite the detailed discussion, the patient refused surgery. During the hospital admission, the patient remained stable with no change in the size of the ascending aorta. Cesarean section was done at 32 weeks of gestation. A boy with a body weight of 1360 g was born. 10 days after delivery, she underwent a bio-Bentall procedure. Follow-ups of the patient and her child were uneventful 12 months after delivery.
