We measured maximal coronary artery conductance in near-term fetal sheep before and after chronic infusion with adenosine to determine whether an increase in coronary flow without hypoxemia results in increased coronary vascular growth. Adenosine was

The effects of right ventricular (RV) systolic pressure (RVSP) load on fetal myocyte size and maturation were studied. Pulmonary artery (PA) pressure was increased by PA occlusion from mean 47.4 ± 5.0 (±SD) to 71 ± 13.6 mmHg ( P < 0.0001) in eight

Chronic fetal anemia produces large compensatory increases in coronary blood flow in the near-term fetal lamb. To determine if increased coronary flow in anemic fetuses is associated with decreased coronary flow reserve or, alternatively, an increase

OBJECTIVE: Our purpose was to determine whether the increase in extravascular fluid in chronic fetal anemia occurs either because of heart failure or despite successful cardiac adaptation. STUDY DESIGN: Right ventricular function curves were obtained

BACKGROUND It has previously been shown that the fetal right ventricle (RV) is sensitive to changes in arterial pressure and that its stroke volume is significantly reduced with acute increases in pulmonary arterial pressure. However, the myocardial
