Xeltis Bioabsorbable Pulmonary Valved Conduit Pivotal Study

This is a multi-center prospective, single-arm, non-randomized, pivotal study that will continue to access the feasibility of the Xeltis Bioabsorbable Pulmonary Valved Conduit in subjects requiring right ventricular outflow tract correction or reconstruction due to congenital heart malformations.

Executive Function Intervention for Children With Complex Congenital Heart Disease

Children with complex congenital heart disease (cCHD) nowadays survive thanks to medical advances into their teenage years and adulthood. However, many of them have difficulties with so-called executive functions. These include skills such as paying attention, planning, self-control, and flexible thinking, which are very important for school, daily life, and becoming independent. These difficulties are linked to changes in the brain and to a higher level of stress. Previous computer-based training programs on their own have either not been very effective, or the effects were lost soon after. In this study, the researchers are testing a newly developed, personalized training program called E-Fit. It combines digital cognitive training, individualized online strategy coaching and analog games. The goal is to find out whether this program can improve executive functions in everyday life for 9-to 13-year-old children with complex congenital heart disease. The study is planed as a randomized controlled trial at the University Children's Hospital Zurich. Children will be assigned either to the training group or to a control group. In addition, the results will be compared with those of a group of healthy children of the same age. The children will visit the University Children's Hospital Zurich three times throughout the whole duration of the study. The first visit will take place before the children start the intervention, the second visit right after the children finished the intervention and the last visit will be 3 months after finishing the intervention. During all these visits neuropsychological assessments, questionnaires, brains scans (MRI) and stress measurements will be collected. The results are intended to help develop effective support programs for these children, improve their well-being, and better prepare them for transition into adulthood.
