Is this trial a fit for you?

Likely a good fit

Children aged 9 to 13 years with complex congenital heart disease and measurable executive function deficits (BRIEF score ≥ 60).

Probably not a fit

Children without executive function deficits or those unable to complete the program (e.g., due to severe neurological conditions) may not benefit.

What this trial studies

This study tests a personalized E-Fit program designed for children with complex congenital heart disease (cCHD) to improve everyday executive functions such as attention, planning, and self-control. The program combines digital cognitive training with individualized online coaching and analog games. Participants are 9 to 13 years old and may include those with certain genetic or syndromal conditions if IQ testing and self-reports can be completed. The study uses a randomized design to assess whether E-Fit leads to meaningful improvements in real-life executive function and daily functioning. The research is led by Bea Latal at University Children's Hospital Zurich.

Why it matters

Potential benefit: If successful, children may show better school performance and greater independence in daily activities thanks to improved executive functioning.

How similar studies have gone: Previous digital training approaches alone have shown limited or short-lived benefits; this study tests a more comprehensive, personalized approach with coaching and hands-on activities.
