[Evaluation of pulmonary flow through the aortic and pulmonary valves of the fetus during normal pregnancy from 20 to 41 weeks of gestation with two dimensional doppler (2dd)].
Doppler data have been analysed in 49 cases for aortic valve and 35 cases for pulmonary valve. For both valves V max, V mean, Aortic Flow and Pulmonary Flow were measured and compared with gestational age.


RESULTS
V max A = 0.85 +/- 0.23 m/s, V max P = 0.72 +/- 0.14 m/s, (p < 0.01); V mean A = 0.28 +/- 0.08 m/s, V mean P = 0.24 +/- 0.06 m/s, (p < 0.02); A Flow = 699 +/- 285 ml/min, P Flow = 740 +/- 310 ml/min, and 275 +/- 100 ml/min/kg for aortic valve and 322 +/- 120 ml/min/kg for pulmonary valve (p > 0.05). There was statistical significant correlation between aortic and pulmonary flow and gestational age and there was no correlation between max velocity and gestational age for these valves.
