  • gt;0.800) for all timing parameters analysed. Multivariate analysis of FTF and ETF in relation to HR, GA and EFW identified HR as the only variable predicting FTF. In contrast, ETF was dependent on both HR and GA. While FTF increased with HR reduction, ETF showed the opposite behaviour, decreasing with HR (more markedly at lower GA) in low-risk fetuses. Most recipient twins with severe TTTS showed reduced FTF and preserved ETF. AoS was associated with decreased FTF and increased ETF in the LV with seemingly different patterns associated with a univentricular versus biventricular postnatal outcome. The majority of fetuses with CoA had FTF and ETF within the normal range in both ventricles. Conclusions: Measurement of FTF and ETF are feasible and reproducible in the fetus. Nomograms account for associations of FTF with HR and ETF with HR and GA. These time fractions are potentially useful for clinical monitoring of cardiac function in TTTS, aortic stenosis and other fetal conditions overloading the heart.
