AbstractSevere symptomatic aortic stenosis in pregnancy carries a poor prognosis. Although cardiopulmonary bypass and surgical repair has been reported to have a low maternal mortality, the fetal risk remains substantial. We report a case in which percutaneous balloon valvuloplasty was performed successfully at 19 weeks' gestation. The procedure restored physiologic left ventricular outflow and improved the aortic valve peak systolic pressure gradient. This allowed progression of the pregnancy to term and an uneventful delivery of a healthy infant, with no maternal complications. Although the long-term efficacy of percutaneous balloon aortic valvuloplasty has not been established, this case report has shown it to be useful as a palliative procedure.
