Intervention for severe aortic stenosis in the fetus: Altering the progression of left sided heart disease

Abstract 

Identification of some forms of congenital heart disease prior to birth may allow for fetal intervention, thereby avoiding progression or development of a more severe anomaly. In this chapter, we discuss the current experience with identification of aortic stenosis in the fetus and the effort to avoid development of hypoplastic left heart syndrome by performance of an in-utero balloon valvuloplasty of the aortic valve.
