Pulmonary artery blood flow patterns in fetuses with pulmonary outflow tract obstruction

ABSTRACT Objectives Fetuses with pulmonary outflow tract obstruction (POTO) have altered blood flow to the pulmonary vasculature. We sought to determine whether pulmonary vascular impedance, as assessed by the pulsatility index (PI), is different in fetuses with POTO compared with normal controls. M...
