Significant infrarenal aortic stenosis in pregnancy: a case report.

Background: Hypertension is common in pregnant women presenting with aortic coarctation or Takayasu's arteritis. Uncontrolled hypertension leads to increased adverse maternal and neonatal events.

Case Presentation: A 36-year-old gravida 2, para 1 Caucasian woman presented at 9 weeks of gestation with headaches but normal blood pressure. She had a past medical history of an in vitro fertilization pregnancy complicated by preeclampsia at 27 weeks of gestation (birth weight 1900 g) and infrarenal aortic stenosis. In the current pregnancy, she received aspirin and calcium as preeclampsia prophylaxis, remained normotensive throughout pregnancy, and was delivered by elective cesarean section at 37 weeks without complications.

Conclusions: This case demonstrates a significant chronic aortopathy in pregnancy with normal fetal growth and uterine blood flow through collateral supply from the internal mammary and epigastric arteries.
