Achieving adequate growth following stage 1 palliation (S1P) for single ventricle heart defects often requires supplemental nutrition through enteral tubes. The effect of specific feeding modalities on infant growth remains unclear.
The National Pediatric Cardiology Quality Improvement Collaborative registry, with data from 47 centers, was queried. Univariate analysis (ANOVA) was used to compare characteristics of patients by feeding modality. Multivariable linear regression was used to study the impact of feeding modality on change in weight for age z-score (WAZ) from S1P discharge to stage 2 palliation (S2P), adjusting for important patient characteristics and post-operative morbidities.
In this cohort of 465 patients, 62% were male and 65% had hypoplastic left heart syndrome. Patients with gastrostomy tubes were older at discharge from S1P and at S2P, and had a shorter interstage period (102 vs. 118 days, p=0.006). Patients in all 5 feeding categories demonstrated improved WAZ score from S1P discharge to S2P. In multivariable analysis, feeding modality was not associated with change in WAZ from S1P discharge to S2P (p=0.72).
Growth during the interstage period from S1P discharge to S2P is not associated with feeding modality. Growth velocity changes during the interstage period may require further investigation given the differences in age at discharge, S2P and interstage length between feeding modalities.

|Oral + nasogastric tube (113)||31 ± 16||146 ± 41||0.3 ± 0.9|
|Nasogastric tube only (63)||39 ± 32||149 ± 49||0.5 ± 1.5|
|Oral + gastrostomy tube (35)||71 ± 34*||172±57#||0.3 ± 0.8|
|Gastrostomy tube only (51)||67 ± 26*||170±57#||0.3 ± 1.1|
