Fetal ventricular outflow tract obstruction (OTO) is congenital heart disease with significant potential for progression before birth as a consequence of the unique nature of the fetal circulation. The pattern of evolution depends upon the timing of development, severity of obstruction and the influence of the OTO on the fetal atrioventricular valve and myocardial function. Critical aortic (AS) or pulmonary (PS) valve stenosis, the two most common forms of fetal OTO, may be associated with progressive ventricular and great artery hypoplasia if presenting early in gestation or with normal ventricular and great artery growth if evolving later in gestation. In some affected fetuses, AS or PS may lead to the evolution of fetal heart failure. This article will review our current understanding of the natural history of fetal AS and PS, experience with fetal intervention and future directions of research.
