Transcatheter Versus Surgical Pulmonary Valve Replacement in Repaired Tetralogy of Fallot

Abstract

Transcatheter pulmonary valve replacement (TC-PVR) is an alternative to surgical PVR (S-PVR) in repaired Tetralogy of Fallot (TOF). The purpose of this study is to compare in-hospital outcomes, hospital costs, and projected 5-year total costs of S-PVR to TC-PVR in patients with repaired TOF. We performed a multicenter, retrospective cohort study of children and adults with TOF ≥ 8 years of age who underwent PVR from January 1, 2010 to December 31, 2016 at 46 centers contributing to the Pediatric Health Information Systems database. Baseline characteristics, in-hospital outcomes, and costs were compared between the two groups. Projected 5-year costs were calculated by combining cost data with published reintervention rates. A total of 194 TC-PVR and 1,072 S-PVR were performed. The baseline characteristics of the TC-PVR and S-PVR groups were not significantly different with the exception of greater age in the TC-PVR group (median age of 17 years vs 15 years, p value <0.001). Discharge mortality, hospital charges and estimated cost, surgical complication rates, and acute kidney failure were not significantly different between the groups. Intensive care unit use, intensive care unit length of stay (LOS), mechanical ventilation use, extracorporeal membrane oxygenation use, and total LOS were lower with TC-PVR than S-PVR. Projected 5-year costs were greater with TC-PVR compared with S-PVR ($64,762 vs $56,536) due to the cost of the transcatheter pulmonary valve and higher reintervention rates. In conclusion, despite longer LOS and greater in-hospital resource utilization for patients with TOF who underwent S-PVR compared with TC-PVR, mortality, and in-hospital costs are the same, and projected 5-year costs are less.
