“…We found no significant difference in mean Tei indices between the right and left ventricles in fetuses. Right ventricular TDITei index was larger than the PD-Tei index (mean difference = 0.02 ± 0.12), and left ventricular TDI-Tei index was smaller than the PD-Tei index (mean difference = -0.02 ± 0.48), which is not consistent with findings in adults and some studies in fetuses, in which the TDI-derived Tei index was significantly larger than the PD index for both ventricles (2,3,20).…”

“…Recently, pulsed Doppler (PD) and tissue Doppler imaging (TDI) methods to measure the Tei index have become easy means of evaluating global systolic and diastolic heart function in healthy and diseased neonates and fetuses. However, there are contradictory results regarding the correlation between Tei indices by PD and TDI in fetuses (2,3). Amoozgar H et al Int Cardiovasc Res J.…”

The result may be implicated in echocardiographic evaluation of neonates by prenatologist and pediatric cardiologist. Background:The myocardial performance index (MPI), also known as the Tei index, was introduced by Tei et al. to evaluate cardiac function in adults with dilated cardiomyopathy. This index is defined as the sum of isovolumic contraction time (ICT) and isovolumic relaxation time (IRT), divided by ejection time (ET). Objectives: To determine the correlation between pulsed Doppler (PD)-and tissue Doppler imaging (TDI)-derived Tei indices in fetuses.Patients and Methods: Right and left ventricle PD and TDI echocardiographic data were obtained from 59 fetuses (11 pregnant women who were positive for anti-SSA-Ro or anti-SSB-La antibodies, 18 women who were referred due to dysrhythmia, and 30 women who had normal clinical findings). Results: Mean fetal gestational age was 27 ± 6.4 weeks. Mean PD Tei index of the mitral and tricuspid valve was 0.58 ± 0.05 and 0.53 ± 0.08, respectively. Mean TDI indices for the mitral and tricuspid valve were 0.56 ± 0.09 and 0.55 ± 0.08, respectively. There were no significant differences between mitral and tricuspid PD-and TDI-derived Tei indices (P = 0.87, P= 0.21), but the Bland-Altman diagrams showed no fine agreement between the indices (the mean difference ± 1 standard deviation of the right ventricular PD-and TDI-derived Tei indices was 0.24 ± 0.02 and 0.29 ± 0.04 for the left ventricle). There were no significant differences in PD-and TDI-derived Tei indexes between groups of evaluated fetuses (Mitral valve: PD-Tei P=0.69, TDI-Tei P=0.49; Tricuspid valve: PD-Tei P=0.41, TDI-Tei P=0.36). Conclusions: Although the mean values of the two indices did not differ significantly, the TDI-derived and PD-derived Tei indices did not have fine agreement.

“…Acharya et al 27 retrospectively evaluated a diverse fetal population ranging from 18 to 41 weeks, included both normal fetuses and those with structural heart disease, and found poor agreement and precision between the two methods. This may have been due in part to the inclusion of both normal and disease fetuses in the same analysis, given that our results show that the tests behave differently in the two groups.…”

“…The peak annular velocities obtained are E' or Ea (early diastolic annular peak velocity), A' or Aa (late∗∗∗diastolic annular peak velocity) and s' or Sa (systolic annular peak velocity) during the ventricular systole. Spectral TDI also allows the calculation of time periods in order to measure the myocardial performance index (MPI‘) as: (ICT’ + IRT')/ET' 44 . TDI has been shown to be feasible in fetuses 45 and normal ranges have been published for both velocities and MPI' 25 .…”

Introduction: Fetal heart evaluation with US is feasible and reproducible, although challenging due to the smallness of the heart, the high heart rate and limited access to the fetus. However, some cardiac parameters have already shown a strong correlation with outcomes and may soon be incorporated into clinical practice. Materials and Methods: Cardiac function assessment has proven utility in the differential diagnosis of cardiomyopathies or prediction of perinatal mortality in congenital heart disease. In addition, some cardiac parameters with high sensitivity such as MPI or annular peak velocities have shown promising results in monitoring and predicting outcome in intrauterine growth restriction or congenital diaphragmatic hernia. Conclusion: Cardiac function can be adequately evaluated in most fetuses when appropriate expertise, equipment and time are available. Fetal cardiac function assessment is a promising tool that may soon be incorporated into clinical practice to diagnose, monitor or predict outcome in some fetal conditions. Thus, more research is warranted to further define specific protocols for each fetal condition that may affect cardiac function.
