Abstract

PURPOSE:

To examine the relationship between cardiac tissue Doppler and peripheral vascular Doppler measurements in fetal anemia.

MATERIALS AND METHODS:

We analyzed high frame rate cardiac Tissue Doppler Imaging (TDI) data files of 26 anemic fetuses. The peak systolic tissue velocity (PSV), peak systolic displacement (PD), and peak systolic strain (PS) were determined in the mid-segment of the ventricular walls (ROI 1 right ventricle (RV), ROI 2 left ventricle (LV)) and in the basal segment of the ventricular walls (ROI 3 tricuspid annulus, ROI 4 mitral annulus). TDI parameters were correlated with established fetal vascular Doppler parameters (peak systolic blood flow velocity (Vmax) in the middle cerebral artery (MCA), pulsatility index (PI) in the MCA, in the umbilical artery (UA), and in the venous duct (DV)).

RESULTS:

The PSV in the LV correlated significantly negatively with the PI in the MCA. Both the PSV and PD in the LV correlated significantly negatively with the PI in the UA. The PS in the RV correlated significantly negatively with the PI in the UA. The left ventricular PSV and PD correlated significantly positively with the PI in the DV. The Vmax in the MCA did not correlate with any systolic myocardial TDI parameter.

CONCLUSION:

In fetal anemia, peak systolic myocardial TDI parameters correlate with vascular Doppler parameters, confirming that TDI is a promising method to evaluate myocardial function in the anemic fetus. This suggests combining both techniques to quantify fetal myocardial function in anemia even more accurately, possibly allowing for the determination of the indication for intrauterine transfusion.
