Outcomes of Complete Surgical Repair Versus Palliative Intervention in
Neonates with Tetralogy of Fallot
Abstract
Background: Surgical management of symptomatic neonates with Tetralogy
of Fallot (TOF) is controversial. Either primary surgical repair (EPSR)
in neonates with TOF or a staged palliation with initial palliative
intervention (PI). Aim: Compare outcomes of neonates with TOF who had
EPSR and those who had PI. Materials and Methods: The study utilized the
US National Inpatient Sample dataset for the years 2000 to 2018.
Patients with EPSR and those with PI (aortic to pulmonary shunt or
cardiac catheter palliative intervention) identified. Results: A total
of 29,292 neonates with TOF were identified; of them 1726 neonates had
EPSR, 4363 had PI. Hospital mortality was similar in both groups (PI
7.4% vs EPSR 8.0%, p = 0.41). Patient in the PI group had more
comorbidities; chromosomal anomalies (PI 13.2% vs. ESPR 7.8%,
p < 0.001), prematurity (PI 15.1% vs. EPSR 10.4%,
p < 0.001), and low birth weight < 2500
grams (PI 15.4% vs. EPSR 10.3%, p < 0.001). Median
length of stay and median cost of hospitalization were significantly
higher in the EPSR (25 days vs. 19 days, and $312,405 vs. $191,863,
respectively, p < 0.001). Conclusion: EPSR had similar
mortality to PI but comes with a higher resource utilization and
complications. If we include the cumulative morbidity and resource
utilization associated with a two staged repair, EPSR could be proven as
a better strategy in symptomatic neonates with TOF. A prospective
superiority study on symptomatic neonates with TOF randomized to either
ESPR or PI is needed to further answer this question.
