Trends and outcomes of pulmonary valve replacement in tetralogy of Fallot

Background Pulmonary valve replacement (PVR) is associated with improvement in symptoms and right ventricular remodeling in patients with tetralogy of Fallot (TOF). There are limited population-based data about outcomes after PVR. We therefore hypothesized a temporal increase in annual volume of PVR and decrease in in-hospital mortality after PVR in the United States. Methods We reviewed the National Inpatient Sample (NIS) for PVR performed in...
