Freedom from reintervention to maintain adequate pulmonary blood flow was similar between infants undergoing modified Blalock-Taussig shunt or ductal stenting as an initial palliative procedure. However, a greater percentage of shunted patients experienced procedure-related complications and distal branch pulmonary artery stenosis. Palliative ductal stenting appears to be a safe and effective alternative to modified Blalock-Taussig in selected infants.

While post-BAV survival is excellent, long-term risks of AI and re-intervention are significant. Acute AI is a more strongly associated with AVR than residual AS. © 2016 Wiley Periodicals, Inc.
