Congenital heart defects in monochorionic twins complicated by selective fetal growth restriction.

In our experience, in MC/DA twin pregnancies, sFGR tripled the prevalence of CHD; hence, women with such pregnancies should be referred to a tertiary care hospital for prenatal and postnatal cardiac evaluation, treatment, and long-term follow-up. In the larger twins, the only major CHD was RVOTA, while a broad spectrum of CHDs was involved in the smaller twins. The higher risk of CHD in MC/DA pregnancies appears to be due to the typical complications of the MC pregnancy rather than to the MC nature of the pregnancy itself.
