Case report

A 32 year-old woman (G3P2) was referred to our office for routine anomaly scan. Fetal cardiac examination revealed the following findings:
  • Conal ventricular septal defect with protodiastolic right to left shunting.
  • Preserved obtuse angle between ascending aorta and ventricular septum with intimately attributed aortic valve to left ventricle, denoting lack of aortic overriding.
  • No other additional VSDs were found.

A male baby was born and chromosomal analysis revealed normal karyotype.  Medical treatment with close observation was started for probability of spontaneous closure before taking decision of surgical correction.

Images 1, 2 and videos 1, 2: 2D and color doppler images of the left outflow tract showing the conal ventricular septal defect with diastolic right to left shunting.
