Figure 5From: Reference values for fetal tissue velocity imaging and a new approach to evaluate fetal myocardial function AV-piston displacement. The displacement of the atrioventricular plane (AV-piston) increased with gestational age. The figure displays a linear regression analysis with 95% confidence interval for the stroke lengths of the left and right ventricle (p < 0,001). LV, Left ventricle; RV, Right ventricle.Back to article page
