This study shows that PLSVC detected in foetus with an otherwise structurally normal heart is associated with an increased risk of extracardiac and genetic abnormalities. Therefore, we would recommend a detailed anatomy scan by an FMU specialist in all cases. There is a notable incidence of genetic and chromosomal abnormalities, which suggests that genetic testing is warranted in this patient population.
