Biventricular impact of mild to moderate fetal pulmonary valve stenosis

To define the pattern of fetal echocardiographic changes associated with isolated pulmonary valve stenosis (PS) and to correlate the echocardiographic findings with neonatal outcome and the need for postnatal pulmonary valvuloplasty within the first 12 months postpartum.

OP26.10: Assessment of fetal cardiac function and structure in monochorionic diamniotic twins with Twin-twin transfusion syndrome before and after fetal therapy

NT-proBNP/TP was elevated (3,475 vs. 518 ng/g, p=0.008), and ductus venosus pulsatility index (DV-PI) was high (1.34 vs. 0.75, p=0.020). Bilateral E/e’ in recipients decreased 4-7 days after FLP (p=0.007). As for donor twins, no significant change was seen in bilateral E/e’. Conclusions: The measurement of fetal E/e’ using DD method was convenient and stable. E/e’ is seemed a useful parameter of fetal cardiac dysfunction in recipient twins, related with amniotic fluid NT-proBNP and DV-PI. Interestingly, bilateral E/e’ of recipients indicated significant decrease within 7 days after FLP. These findings might imply FLP improves pathological condition of diastolic dysfunction in recipient twins.
