Aortic stenosis is uncommon during pregnancy. Five cases are described in which clinical management was facilitated by the use of Doppler echocardiography to assess the severity of disease and pulmonary artery catheterization to manage maternal hemodynamics. Regional anesthesia was used without complication. In patients with severe stenosis, significant morbidity and mortality were experienced when aortic valve replacement was delayed beyond the postpartum period.
