title: Usefulness of serial brain natriuretic peptide measurements for managing aortic valve stenosis in pregnancy.
abstract: Among developed countries, valvular aortic stenosis (AS) in pregnant women is primarily due to a congenitally bicuspid aortic valve, which occurs in approximately 1% of the general adult population. Most asymptomatic patients and those with mild to moderate AS can be managed conservatively to full-term pregnancy. However, those with more severe AS with symptoms require more aggressive treatment. The medical management of severe symptomatic AS is not ideal; hence, these women are typically treated with percutaneous balloon valvuloplasty or surgical aortic valve replacement. However, both interventions are associated with inherent risks. In addition, symptoms such as dyspnea and decreased exercise tolerance are commonly exhibited in normal pregnant women, making it difficult to distinguish symptoms associated with normal pregnancy from those caused by AS. We report the first case of congenitally bicuspid severe AS in pregnancy that was successfully managed medically to full term by following consecutive brain natriuretic peptide levels.
