461: Fetal cardiac function in recipient fetuses of stage 4 twin-to-twin transfusion syndrome undergoing fetoscopic laser coagulation of placental anastomoses

Abstract

Cardiac dysfunction is common in the recipient fetus of twin-to-twin transfusion syndrome (TTTS). Information on fetal cardiac dysfunction in stage 4 TTTS (fetal hydrops) is lacking. In this study, we document severity of fetal cardiac dysfunction in stage 4 TTTS and assess evolution of cardiac function longitudinally after fetoscopic laser.
