Figure 5. Ejection fraction as a function of gestational age in the presence of increased placental vascular impedance to flow.

Figure 5

Ejection fraction (EF) in fetuses with an umbilical artery pulsatility index > 95th percentile (ABN) were compared to 184 normal fetuses (NL)40 (A: left ventricular EF; B: right ventricular EF). Mean ejection fraction (adjusted for gestational age) (%) was significantly higher for both the left ventricle (ABN: 82.4 vs. NL: 70.4; p < 0.0001) and right ventricle (ABN: 66.0 vs. NL: 60.8; p < 0.0001).
