“…A physiologically high E/E' ratio is observed because myocardial maturation is insufficient in early pregnancy. In the following weeks of gestation, the E/E' ratio decreases progressively as the result of increased myocardial compliance 37 . The present study showed that mitral and tricuspid E/ E' ratios were higher in the EO‐FGR and LO‐FGR fetuses.…”

Objective To compare the fetal cardiac morphology and functions of early‐onset fetal growth restriction (EO‐FGR) and late‐onset fetal growth restriction (LO‐FGR) groups with gestational weeks‐matched controls. Methods A total of 164 pregnant women were included, 28 of whom were in the EO‐FGR group, 54 in the LO‐FGR group, and 82 in the control group. Fetal echocardiographic evaluation was performed with two‐dimensional, M‐mode, tissue Doppler imaging (TDI), and pulsed wave Doppler. Results Fetal cardiac morphologic measurements and diastolic and systolic functions changed in EO‐FGR and LO‐FGR fetuses compared with controls. The EO‐ and LO‐FGR fetuses had reduced right and left cardiac output, increased myocardial performance index, and significantly higher mitral and tricuspid E/E' ratios compared with controls. The EO‐FGR fetuses had lower mitral and tricuspid E and E' values. In LO‐FGR fetuses, mitral and tricuspid E' values were lower than in their controls (P = 0.001 and P < 0.001). On the other hand, the mitral and tricuspid E values were not significantly changed (P = 0.107 and P = 0.196). Conclusion We hypothesized that EO‐FGR and LO‐FGR fetuses had insufficient myocardial maturation. Especially in the LO‐FGR fetuses, TDI is the earliest and most sensitive technique to show subtle changes in fetal cardiac functions.

“…Myocardial performance index (MPI) was calculated (isovolumetric contraction time [IVCT] + isovolumetric relaxation time [IVRT]/ ET) from the obtained waveform 11 . The early diastole (E'), atrial contraction (A'), and systole (S') peak velocities were measured by placing the cursor on the lateral side of the mitral and tricuspid valve with an insonation angle of fewer than 30° without angle correction with TDI 12–17 . The three clearest waveforms and valve clicks were measured at which fetal heart rate was within the normal range (120–160 bpm), and the measured values were averaged.…”

Objective We aimed to evaluate and compare fetal cardiac morphology and functions of pregnant women with familial Mediterranean fever (FMF) and healthy pregnant women. Methods The study included 34 pregnant women with FMF and 68 healthy pregnant women matched with maternal age, gravidity, parity, gestational age, and pre‐pregnancy body mass index (BMI) in 34th–37th gestational weeks. Fetal echocardiographic evaluation was performed with two‐dimensional (2D) imaging, M‐mode imaging, pulsed wave (PW) Doppler, and tissue Doppler imaging (TDI). Results Fetal cardiac morphological measures, including cardiothoracic ratio, cardiac axis angle, right and left ventricular area, sphericity index, and ventricular septal thickness was similar in both groups. Compared with the control group, myocardial performance index (MPI), which indicates global myocardial performance, was significantly higher, and ejection time (ET) was significantly shortened in the FMF group. In addition, which shows the diastolic functional parameters such as, tricuspid E wave, E/A, E/E' ratio, and mitral E wave, E/A, E/E' ratio, were significantly higher; tricuspid A and mitral A waves were significantly lower. We found that mitral and tricuspid annular plane systolic excursion (MAPSE and TAPSE) were significantly lower in those with FMF duration over eight years than those with FMF duration less than 8 years. Conclusion There is no fetal cardiac morphological change in pregnant women with FMF. However, there may be changes in diastolic function. As the maternal FMF duration increases, systolic functions may also change.

“…TDI also allows measurement of MPI similar to pulsed Doppler. The E/E' ratio, the ratio of early tricuspid annular velocity (E') to early peak filling velocity of the tricuspid valve (E), is one of the echocardiographic parameters of diastolic function in the prenatal period 7 . Some studies have investigated fetal cardiac functional changes in fetuses with IUGR using the s-TDI technique 18,22 .…”

Aim:This study aims to investigate the effects of maternal asthma on fetal cardiac functions. Methods:The study was planned with 30 pregnant women who presented to a tertiary health center and were diagnosed with asthma and 60 healthy controls with similar gestational ages. The fetal echocardiographic assessment was assessed between 33 and 35 weeks of gestation with pulsed-wave Doppler (PW), M-mode, and tissue Doppler imaging (TDI). Fetal cardiac functions were compared between maternal asthma and control group. Cardiac functions were assessed according to the duration of maternal asthma diagnosis, as well. Results:Early diastolic function parameters, tricuspid E wave (p=0.001), and tricuspid E/A ratio (P=0.005) were significantly lower in the group with maternal asthma. TAPSE and MAPSE values were statistically lower in the study group than in the control group; p=0.010 and p=0.012, respectively. Parameters assessed with TDI (E’, A’, S’, E/E’, and MPI’ of tricuspid valves) and global cardiac function parameters assessed with pulsed-wave Doppler like myocardial performance index (MPI) and left cardiac output (LCO) were similar between groups (p> 0.05). Although, MPI did not change between groups, and the isovolumetric relaxation time (IVRT) value was prolonged in maternal asthma cases (p=0.025). Conclusion:We found that maternal asthma disease causes alteration in fetal diastolic and early systolic cardiac functions, but the global fetal cardiac function does not change. Diastolic heart function values also varied with the duration of maternal asthma. Prospective studies are needed to compare fetal cardiac functions with additional patient groups according to disease severity and type of medical treatment.
