Summary

This study followed 179 children aged 4 to 16 who were born from twin pregnancies complicated by twin-to-twin transfusion syndrome (TTTS). Researchers checked their heart function, blood pressure, kidney health, and blood sugar control to see if the condition during pregnancy caused long-term health issues. The goal is to better understand these effects and improve future care for affected children.
