What is the role of balloon dilatation for severe aortic stenosis during pregnancy?

Abstract

The use of aortic balloon valvuloplasty in pregnancy is useful as a palliative procedure, allowing deferral of valve replacement until after birth. Echocardiographic features alone are not enough to decide on management, and symptoms play a vital role in determining risk. The use of transesophageal echocardiography during the procedure significantly reduces fluoroscopy time.
