Aim: To establish reference range values for peak myocardial tissue Doppler velocity (MTD) and myocardial performance index (MPI) of the left ventricle (LV), the right ventricle (RV), and the interventricular septum (IVS) at 20 to 36+6 weeks of gestation using spectral tissue Doppler.Material and methods: This cross-sectional study was conducted among 360 lowrisk singleton pregnancies. MTD during systole (S’), and early (E’) and late diastole (A’), and MPI’ were assessed by placing sample volume at the basal segment of the LV free wall, the RV free wall, and the IVS, respectively. Polynomial regression was used to obtain the best-fit curves for MTD and MPI’ measurements as a function of gestational age (GA), and adjustments were made using the determination coefficient (R2). Intra- and inter-observer reproducibility was evaluated using the concordance correlation coefficient (CCC).Results: All MTD velocities (cm/s) progressively increased with advancing GA (p<0.0001). Mean LV MTD values were 4.19 to 6.86 for S’, 3.52 to 7.22 for E’, and 6.85 to 9.19 for A’; mean RV MTD were 4.85 to 7.97 for S’, 4.49 to 8.66 for E’, and 8.44 to 11.20 for A’; and mean IVS MTD values were 3.75 to 5.78 for S’, 3.34 to 5.79 for E’, and 5.88 to 7.98 for A’. LV MPI’, RV MPI’, and IVS MPI’ did not significantly change with advancing GA. The CCC values for MTD were predominantly greater than 0.70, while those for MPI’ were <0.70.Conclusions: Reference values for the fetal MTD and MPI’ of RV, LV and IVS using tissue Doppler between 20 and 36+6 weeks of gestation were described.

A New Technique

Background: One of the consequences of IUGR is the development of cardiac diastolic dysfunction in fetuses. Tissue doppler in echocardiography is a new technique to detect myocardial tissue function and can act as a useful tool in the identification of this complication. Hence we decided to undertake this study to assess the utility of myocardial tissue doppler in detecting foetal cardiac dysfunction in IUGR. It was a prospective case control study in a tertiary care teaching hospital.Methods: Foetal cardiac function in the third trimester of pregnancy was evaluated with the help of myocardial tissue doppler and compared between IUGR and normal growth babies and correlated with vessel doppler findings and neonatal outcomes.Results: There were sixty two IUGR and fifty eight normal growth babies in the study. In babies with IUGR, particularly the ones with severe IUGR, abnormal vessel doppler and adverse neonatal outcomes, right ventricular MPI was found to be significantly lower. However, the variable had a poor sensitivity (40%) in detecting fetuses at risk for poor neonatal outcomes.Conclusions: Myocardial tissue doppler shows right sided cardiac dysfunction in IUGR babies in comparison to normal growth babies It is however not a sensitive indicator of adverse perinatal outcome in IUGR babies.
