Role of the Pulmonary Circulation in the Distribution of Human Fetal Cardiac Output During the Second Half of Pregnancy

BACKGROUND: By using Doppler echocardiography, we determined the normal distribution of human fetal combined cardiac output (CCO) from the left and right ventricles. We also established weight-indexed pulmonary and systemic vascular resistances (Rpi and Rsi, respectively) and changes during the seco... View More
