Figure 36. Selected video frames from suprasternal notch view in a neonate with the supra-diaphragmatic type of total anomalous pulmonary venous connection with pulsed Doppler recording form two different portions (A, B) of the vertical vein (VV); the Doppler velocities are low, suggesting that there is no obstruction. Reproduced from Ref.^[24]. PW: Pulse width; SV: sample volume; WF: width frequency.
