Abstract

Our aim was to evaluate postoperative morbidity and mortality following initial intervention, comparing primary repair versus palliative shunt in the setting of ductal-dependent tetralogy of Fallot. When neonatal surgical intervention is required, controversy and cross-center variability exists with regard to surgical strategy. The multicenter Pediatric Health Information System database was queried to identify patients with TOF and ductal-dependent physiology, excluding pulmonary atresia. Eight hundred forty-five patients were included-349 (41.3%) underwent primary complete repair, while 496 (58.7%) underwent initial palliation. Palliated patients had significantly higher comorbid diagnoses of genetic syndrome and coronary artery anomalies. Primary complete repair patients had significantly increased morbidity across a number of variables compared to shunt palliation, but mortality rate was equal (6%). Second-stage complete repair was analyzed for 285 of palliated patients, with median inter-stage duration of 231 days (175-322 days). In comparison to primary complete repairs, second-stage repairs had significantly decreased morbidity and mortality. However, cumulative morbidity was higher for the staged patients. Median adjusted billed charges were lower for primary complete repair ($363,554) compared to staged repair ($428,109). For ductal-dependent TOF, there is no difference in postoperative mortality following the initial surgery (6%) whether management involves primary repair or palliative shunt. Although delaying complete repair by performing a palliative shunt is associated with a shift of much of the morbidity burden to outside of the newborn period, there is greater total postoperative morbidity and resource utilization associated with the staged approach.
