Impact of Early Fortini Initiation on Growth and Interstage Outcomes in Infants With Single Ventricle Physiology

Fortini, a commercially available formula providing 30 kcal/oz, is commonly used in older children with failure to thrive or feeding intolerance. It offers the theoretical benefit of providing higher caloric density in a lower volume, which may be advantageous in infants with single ventricle physiology, who often have limited volume tolerance and high metabolic demands.

Standard infant formulas (including hydrolyzed formulas) fortification to 24-30 kcal/oz
