[Clinical study of fetal echocardiography].
92 fetuses from 52 women who were about to undergo midtrimester termination of pregnancy and 40 fetuses at high risk were studied by M-mode, 2D and pulsed Doppler echocardiography. One fetus of 24 weeks gestation was found to have a cardiac tumor. The pathological diagnosis was rhabdomyoma. The right ventricular tumor was located between the tricuspid and septum. It obstructed the tricuspid valve and caused tricuspid regurgitation and bradycardia. The measurement of atrial and ventricular dimensions by fetal echocardiography in 91 normal fetuses showed an average RV/LV ratio of 1.11. Doppler velocities of mitral and tricuspid valves showed a Peak A/peakE ratio of 1.
