Native Right Ventricular Outflow Tract Stenting in a Child with Tetralogy of Fallot and Absent Left Pulmonary Artery

Although percutaneous placement of intravascular stents in congenital heart disease is a common practice, there are few reports regarding native right ventricular outflow tract (RVOT) stenting in children[1]. Stenting of conduit stenoses are more commonly reported[2]. In the preoperative setting, palliation of significant cyanosis by balloon valvuloplasty or RVOT stenting has been advocated by some as a means for reducing symptomatic cyanosis in patients with severe annular hypoplasia. Improvement in antegrade flow is thought to simultaneously enhance pulmonary arterial growth by augmenting pulmonary blood flow. Most of transcatheter interventions for relieving RVOT were done for conduit stenosis. There are few reports about native RVOT stenting, and to the best of our knowledge there are very few reports on native RVOT stenting in tetralogy of fallot (TOF) with absent left pulmonary artery[3].
