Prenatal Diagnosis of Tetralogy of Fallot in a Fetus with Maternal Gestational Diabetes Mellitus, a Case Report

Gestational diabetes mellitus (GDM) is a teratogenic condition for the fetus. Congenitalmalformations among the newborns of diabetic mothers is 5-times greater than generalpopulation. Tetralogy of fallot is a common form of congenital heart defect. We would like toreport a diagnosed case of fetal tetralogy of fallot based on findings including a ventricular septaldefect (VSD), aortic valve overriding, bidirectional shunt via VSD in aortic long axis view, inaddition to anomalies on the three-vessel view with small pulmonic annulus in a high risk motherwith GDM with a gestational age of 19 weeks. It appears that although the risk of fetal cardiacmalformations may be highest in women with GDM, all pregnancies of pre-gestational diabetesand GDM are at increased risk, given this, regular fetal echocardiographies should be consider inwomen with GDM.
