Figure 2 Tracing of the right pulmonary artery band Doppler (red) with measurement of the peak systolic velocity (green) and diastolic velocity (blue)
Figure 3 Left pulmonary artery band Doppler pre-atrial intervention showing low diastolic and notching in two patients (a,b) and a schematic (c). Left pulmonary artery band Doppler post-atrial intervention showing higher diastolic pressure and less prominent notching in the same two patients (d,e) and a schematic
