Key result
Balloon dilatation of the aortic valve was successfully performed in two pregnant women with severe aortic stenosis, resulting in the delivery of healthy infants and maternal well-being at one year.
Why the study?
Does balloon dilatation of the aortic valve improve maternal and fetal outcomes in pregnant patients with severe aortic stenosis?

Does balloon dilatation of the aortic valve improve maternal and fetal outcomes in pregnant patients with severe aortic stenosis?
Balloon dilatation of the aortic valve serves as a useful palliative procedure for pregnant women with severe aortic stenosis, avoiding the fetal risks associated with cardiopulmonary bypass.
May support palliative balloon valvuloplasty in pregnant severe AS; leaves open need for prospective data before wider adoption.
The outcome of unrelieved severe symptomatic aortic stenosis in pregnancy is poor. Though the valve lesion can be corrected surgically before delivery at a low risk to the mother, cardiopulmonary bypass during pregnancy carries a high risk to the fetus. Two patients in the second trimester of pregnancy were successfully managed with balloon dilatation of the aortic valve. Both delivered healthy infants and were well a year later. Balloon dilatation of the aortic valve is a useful palliative procedure in the management of pregnant women with severe aortic stenosis.

Banning et al. (1993) conducted a case report in Severe aortic stenosis in pregnancy (n=2). Balloon dilatation of the aortic valve was evaluated on Successful management, delivery of healthy infants, and maternal well-being at 1 year. Balloon dilatation of the aortic valve was successfully performed in two pregnant women with severe aortic stenosis, resulting in the delivery of healthy infants and maternal well-being at one year.
