Figure 26. Selected video frame of continuous wave Doppler across the ventricular septal defect of the same patient as shown in [Figure 25]. Low velocity flow across the ventricular septal defect (VSD) suggests that the defect is non-obstructive. Reproduced from Ref.^[19]. Vmax: Maximum velocity; PG: peak gradient; RSVP: right ventricular systolic pressure.
