- Echocardiographic Assessment: Subcostal Short Axis
- Assess for anomalous venous drainge into IVC (2D +C)
- Spectral Doppler of any abnormal structures entering IVC to assess Doppler waveform (venous pattern) and for evidence of stenosis (assess mean gradient by spectral Doppler)
- Transducer on abdomen just below xyphoid process
- Notch at 6 o'clock
- Probe tilted towards patient's right shoulder
