• Infracardiac total anomalous pulmonary venous return
    • Descending vertical vein seen draining into the portal circulation
  • Infracardiac total anomalous pulmonary venous return
    • Vertical vein drains inferiorly into the portal vein/ductus venosus
    • Turbulent flow noted at the insertion of the vertical vein into the portal vein/ductus venosus concerning for pulmonary venous obstruction

Echocardiographic Assessment: Subcostal IVC

  • Vertical vein anatomy and course 
    • Assess by 2D, color and spectral Doppler for evidence of turbulence/obstruction
      • most commonly as the vertical vein descends below the diaphram and enters the portal venous circulation
  • Inferior vena cava/portal vein/ductus venosus
    • Size and flow by 2D, color and spectral Doppler
    • Assess for connection to vertical vein
    • Assess for obstruction as vertical vein connects to portal venous circulation

  • Probe position in subxyphoid location
  • Rotate probe so notch at 12 o'clock
  • Tilt to patient's left
