Women with type 1 DM are often referred for detailed fetal
echocardiography because of the recognised risk for fetal CHD [13,14].
Women with GDM are also often referred to our unit for assessment
of the fetal heart. Our initial hypothesis was that GDM was an
inappropriate referral reason and women with GDM do not have an
increased risk of CHD in their offspring. Therefore this observational
study was undertaken to assess the occurrence of fetal CHD in women
with reported gestational diabetes referred to our fetal cardiology unit
and to evaluate whether fetal echocardiography should continue to be
routinely offered to these women.
