    • Cardiomegaly with enlargement of right atrium, right ventricle and left ventricle
  • Vein of Galen Malformation
    • Cardiomegaly with right atrial, right and left ventricular dilation
    • Mild tricuspid and mitral regurgitation
  • Vein of Galen Malformation
    • Dilated superior vena cava and innominate vein
  • Vein of Galen Malformation
    • Dilated SVC and innominate vein
  • Vein of Galen Malformation
    • Flow reversal noted in the distal transverse arch and aortic isthmus which extends into the carotid arteries due to continuous flow from the vein of Galen AVM
  • Vein of Galen Malformation
    • A wave reversal noted in the ductus venosus consistent with an elevated right ventricular end diastolic pressure
  • Vein of Galen Malformation
    • Elevated middle cerebral artery peak systolic velocity with a decreased pulsatility index 
    • Increased diastolic flow secondary to steal from the aorta
  • Vein of Galen Malformation
    • Near fusion of tricuspid valve inflow with a dominant E wave and low A wave compatible with RV diastolic dysfunction and reduced filling of the RV during atrial systole
    • These findings are consistent with elevated right ventricular end diastolic pressure
