Abstract

Recurrent or residual right ventricular outflow tract obstruction after early surgical repair of congenital heart disease is one of the most frequent indications for either surgical or transcatheter reintervention. Transcatheter stent implantation across the stenotic right ventricular outflow tract or conduit is a safe and effective alternative to surgical reintervention. However, chronic deleterious effects of pulmonary regurgitation can potentially counterbalance the early improvement in clinical and hemodynamic parameters, sometimes necessitating further intervention. While there are several studies documenting safe and effective palliation by transcatheter right ventricular outflow tract stenting in infants with tetralogy of Fallot, literature on isolated infundibular stent implantation sparing the normal pulmonary valve in postoperative infundibular restenosis is very scant. We report our experience of safety and feasibility of transcatheter right ventricular outflow tract stent implantation while preserving the native pulmonary valve function in two children with infundibular stenosis after surgical repair of congenital heart disease.
