Fetal circulation in left-sided congenital heart disease measured by cardiovascular magnetic resonance: a case–control study

The distribution of blood flow in fetuses with congenital heart disease (CHD) is likely to influence fetal growth, organ development, and postnatal outcome, but has previously been difficult to study. We present the first measurements of the distribution of the fetal circulation in left-sided CHD made using phase contrast cardiac magnetic resonance (CMR).Twenty-two fetuses with suspected left-sided CHD and twelve normal controls underwent fetal...
