Stenting of modified and classical Blalock-Taussig shunts--lessons learned from seven consecutive cases.

In neonates and infants with a shunt-dependent pulmonary circulation, stenosis of the shunt needs to be treated aggressively to prevent a fatal outcome. We report the technique and outcome in seven consecutive neonates and infants with Blalock-Taussig shunt stenosis, who were treated with intraluminal stents. Stenting of classical or modified Blalock-Taussig shunts is technically feasible and can be used as a rescue procedure. Neointimal dissection is less likely compared with balloon angioplasty of the shunt alone.
