Figure 6

Ejection fraction (stroke volume / end diastolic volume x 100) for the left (A) and right (B) ventricles decreased with increasing gestational age. The regression line with the 5% and 95% CI’s is plotted with the regression equation, adjusted r2, and p value for each. Additionally, the left side was significantly greater than the right (Left: 72.2%, IQR: 64 – 78; Right: 62.4%, IQR: 56 – 69; p<0.001).
