Fetal atrioventricular septal defect
Fetal case of complete atrioventricular septal defect. The atrial and ventricular components with common atrioventricular orifice. There is balanced ventricles with no left or right-sided atrioventricular valvular regurgitation. No evidence of LVOT obstruction or antenatal suspicion of coarctation. Both atrioventricular valves are at the same level (in normal anatomy: tricuspid valve implanted lower than the mitral valve).
