BACKGROUND: Single-ventricle patients require a series of surgeries, with the final stage being the Fontan. This form of circulation results in several long-term complications, but the impact and consequences of nutrition status remain unclear. We sought to evaluate the incidence of malnutrition in Fontan patients and the impact on outcomes.
METHODS: This study was a retrospective cohort study of children who underwent Fontan surgery between 1997 and 2018. Clinical, demographic, and nutrition data were collected, including weight, height, body mass index (BMI), and their respective z scores (z score for weight-for-age [WAZ], z score for height-for-age [HAZ], and z score for BMI-for-age [BMIZ]) pre-Fontan, at discharge, 6 months, and 1, 5, and 10 years post-Fontan. Malnutrition status was categorized using the American Society for Parenteral and Enteral Nutrition guidelines and the Michigan MTool. Fontan failure was defined as listing for heart transplant or death.
RESULTS: Of the 69 patients, moderate-severe malnutrition occurred at any time point in 11% (n = 8) by WAZ, 16% (n = 11) by HAZ, and 6% (n = 4) by BMIZ. Moderate-severe malnutrition persisted in 6.5%-12.9% at 10 years post-Fontan. Compared with the pre-Fontan period, there was no change in these parameters over time. There was no statistically significant difference in Fontan failure between degrees of pre-Fontan malnutrition.
CONCLUSION: There is a 6%-16% incidence of moderate-severe malnutrition in Fontan patients. Malnutrition is a condition that remains present in follow-up. There was no association with anthropometric parameters and transplant-free survival. A prospective multi-institutional study is needed to understand the impact of malnutrition on long-term outcomes.
