Fig 1 Changes in Doppler cerebral flow patterns. (A) Proximal callosomarginal and (B) right medial cerebral arteries after bilateral pulmonary artery banding (PAB). Data are expressed as mean ± standard deviation. Vs, Vd, and Vm represent the peak systolic, end-diastolic, and mean velocities, respectively.
