Figure 3. Cardiac output adjusted by estimated fetal weight of the left and right ventricles in the presence of increased placental vascular impedance to flow.

Figure 3

Cardiac output adjusted for estimated fetal weight (EFW) in fetuses with an umbilical artery (UA) pulsatility index > 95th percentile (ABN) were compared to 184 normal fetuses (NL).40 For the left ventricle, the median CO adjusted for EFW (mL/min/kg) was significantly lower in the presence of increased placental vascular impedance to flow (ABN: 67.8, IQR: 44.7 – 84.1 vs. NL: 90.0, IQR: 56.0 – 127.5; p < 0.05). However, for the right ventricle, the median CO adjusted for EFW (mL/min/kg) was not significantly different between ABN and NL groups (ABN: 77.4, IQR: 66.1 – 123.8 vs. NL: 99.9, IQR: 72.2 – 126.0; p = NS).
