Testing a specialized formula to help babies with single-ventricle heart disease grow better

This trial is testing whether Fortini, a specially formulated infant food that provides more calories in a smaller volume, helps babies with single-ventricle heart disease (a serious heart condition requiring surgery) grow better after their first operation. Babies with this condition often struggle to gain weight and have difficulty tolerating large feeding volumes. The study compares this medication to standard fortified infant formulas to see if it improves weight gain, feeding success, and reduces stress on families.

Babies with single-ventricle heart disease are at high risk during the period between their first and second heart surgeries, and poor weight gain during this time predicts serious complications. While this treatment is sometimes used in older children, no one has carefully studied whether it is safe and effective for very young babies with this condition, so this research aims to fill that gap.
