Abstract Objective This study aims to compare completion rates and reproducibility of myocardial performance index (MPI) using conventional spectral Doppler versus tissue Doppler in an unselected high-risk third trimester population. Study Design This was a prospective cross-sectional study of high-risk pregnancies at ≥28 + 0 weeks’ gestation. Conventional spectral and tissue Doppler MPI of the left ventricle (LV) and right ventricle (RV) was attempted on all patients. Results Seventy-nine pregnancies were evaluated. LV tissue Doppler MPI was completed more frequently than LV conventional spectral Doppler MPI (63/79, 79.7% vs. 45/79, 55.7%), p-value <0.01. RV tissue Doppler MPI was completed more frequently than RV conventional spectral Doppler MPI (68/79, 86% vs. 42/79, 53.2%), p-value <0.01. In obese subjects (n = 50) LV tissue Doppler MPI was completed more frequently than LV conventional spectral Doppler MPI (37/50, 74% vs. 26/50, 52%), p-value <0.01. RV tissue Doppler MPI was completed more frequently than RV conventional spectral Doppler MPI (40/50, 80% vs. 25/50, 50%), p-value <0.01. intraclass correlation coefficient for all modalities ranged between 0.73 and 0.93, except for LV conventional spectral Doppler intraobserver variability which was 0.22. Conclusion Tissue Doppler had statistically higher completion rates than conventional spectral Doppler, including the obese subgroup, with evidence of strong reproducibility in the third trimester.

Background: Cardiomyopathy usually causes a cardiac dysfunction resistant to treatment due to anthracycline. This study aimed to evaluate the changes in Tei-Index (myocardial performance index) in patients with malignancies treated with anthracycline. Material and Methods: This case-control study was done on 15 children who were treated with low-dose anthracycline (1-199mg/kg) called group A and 15 children who were treated with high dose (>200mg/kg) anthracycline called group B after acquiring consent from their parents. Children with no abnormality in Echo-Doppler results were included in this study. The patients’ age range between 1- 17 years with a mean age of 6.57 years. Another group of healthy children were assigned to group C as a control group who had not received chemotherapy. The first echo was performed right before the treatment and the second one, two weeks after completing chemotherapy.  Data were analyzed by the SPSS statistical software. Results: Changes in mean Tei-index in group A were 0.36 ± 0.04 before treatment and 0.43 ± 0.11 after treatment. Changes in mean Tei-index in group B were 0.37 ± 0.04 before treatment and 0.45 ± 0.06 after treatment. There was no significant difference between the two groups using the independent T-test. (p-value= 0.57). No significant correlation between the changes in mean ejection fraction (EF) and treatment was found in the three groups (p-value=0.45). Conclusion: This study showed a change in the Tei-index (MPI) in patients receiving anthracycline; regardless of the dosage, they got in their regimen. Given the use of anthracycline, any abnormal cardiac finding can alert the physicians to the possibility of cardiomyopathy, hence scheduling routine follow-ups are necessary.

Abstract Introduction The myocardial performance index (MPI) has been proposed to evaluate cardiac dysfunction in newborns from diabetic mothers. Although MPI is routinely assessed in newborns, its role in the evaluation of fetuses from women with hyperglycemia in pregnancy (HIP) is still under evaluation. We aimed to evaluate the differences in third trimester fetal MPI in pregnant women with hyperglycemia compared to healthy controls. Materials and Methods Seven electronic databases were searched for all studies assessing women with HIP who underwent evaluation of fetal left MPI during pregnancy compared to a control group. The summary measures were reported as mean differences (MD) in the mean fetal left MPI between women with HIP and healthy controls, with a 95 % confidence interval (CI). A post hoc subgroup analysis based on the type of HIP – pregestational diabetes, GDM, or gestational impaired glucose tolerance (GIGT) – was performed as an additional analysis. Results 14 studies assessing 1326 fetuses (580 from women with HIP and 746 from controls) were included. Women with HIP had a significantly higher mean left fetal MPI compared to controls (MD 0.08; 95 %CI: 0.05 to 0.11; p < 0.00 001). Subgroup analysis according to the type of HIP concurred with the overall analysis for women with DM (MD 0.07; 95 %CI: 0.01 to 0.13; p = 0.02) and for women with GDM (MD 0.012; 95 %CI: 0.07 to 0.17; p < 0.00 001) but not for women with GIGT (MD –0.01, 95 % CI –0.28 to 0.27; p = 0.96). Conclusion Fetal left MPI is increased in pregnancies with HIP appearing as a potential marker of cardiac dysfunction.
