Starting Fortini after the first heart surgery to help infants with single-ventricle defects grow better

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

Not applicable Interventional Driscoll Children's Hospital · NCT07087782

This trial will see if giving Fortini, a high-calorie low-osmolality formula, at hospital discharge helps infants with single-ventricle heart defects gain more weight before their next surgery.

What this trial studies

Infants who have undergone Stage 1 palliation for single-ventricle physiology will be randomly assigned at discharge to receive either Fortini (30 kcal/oz) or the current standard high-calorie formula. The study follows infants through the interstage period up to their Stage 2 surgery (about 4 months) and measures weight gain as the primary outcome. Secondary outcomes include feeding tolerance, intake volumes, hospital readmissions, and caregiver-reported feeding burden. About 100 infants will be enrolled at a single center (Driscoll Children's Hospital) to determine whether early Fortini initiation improves growth without increasing adverse effects.

Who should consider this trial

Good fit: Infants ≤6 months with single-ventricle physiology who are medically stable and ready for discharge after Stage 1 surgery and who feed orally or via NG/gastrostomy tube, with a parent or guardian able to consent.

Not a fit: Infants with gastrointestinal contraindications (e.g., NEC, short gut, malabsorption), proven cow's milk protein allergy, current enrollment in another interventional nutrition study, or those unable to complete outpatient follow-up are unlikely to receive benefit from this intervention.

Why it matters

Potential benefit: If successful, Fortini could help these infants gain weight more effectively between surgeries and potentially reduce complications or readmissions before the second operation.

How similar studies have performed: Retrospective reports and clinical experience suggest that increasing caloric density can improve weight gain, but Fortini has not been tested prospectively in infants under 6 months with single-ventricle physiology.
