Acute Interventions for Stenosed Right Ventricle-Pulmonary Artery Conduit Following the Right-Sided Modification of Norwood-Sano Procedure

Abstract

The RV-PA conduit stenosis is a life-threatening complication after the modified Norwood Stage I procedure. This may require urgent surgery to replace the conduit or to perform a cavo-pulmonary shunt but as an alternative, transcatheter stent placement can be used with equal effectiveness and with a low risk of complications. The catheter approach is less invasive and the results show that it is an excellent option to relieve the stenosis even in the right-sided RV-PA conduit.
