1. Comportamento do fluxo venoso pulmonar durante o ciclo respiratório fetal
Introdução- Os movimentos respiratórios têm influência na circulação fetal. Sua presença indica um sistema nervoso intacto, não deprimido, refletindo o bem-estar do concepto. Acredita-se que, em apnéia, a pressão exercida pelos órgãos intratorácicos no coração fetal, em particular os pulmões não expandidos, limita a distensibilidade ventric

2. Fetal echocardiography in detecting anomalous pulmonary venous connection: four false positive cases.
Prenatal detection of congenital heart disease is possible from the 16th week of pregnancy, the ideal time being the mid-trimester, when most cardiac abnormalities can be detected. However, identification of anomalous pulmonary venous connection is difficult before birth and the sensitivity of fetal echocardiography in detecting this anomaly is low. Four cas

3. In utero right ventricular output in the fetal lamb: the effect of heart rate.
1. The effect of heart rate on right ventricular output was examined in six lambs during a period extending from 126 to 139 days of gestation. The fetuses had been surgically instrumented at least four days previously with a main pulmonary artery flow probe, right ventricular dimension transducers and left and right atrial pacing electrodes. 2. During sponta
