“…In this study, we found the ventricular global longitudinal strain decreased significantly in the third trimester of pregnancy. This is similar to the previous studies, [13,14]. Although there are no significant changes in global radial and circular strain parameters during pregnancy, left ventricular rotation and twist values increase significantly in the 3rd trimester [13,14].…”

“…This is similar to the previous studies, [13,14]. Although there are no significant changes in global radial and circular strain parameters during pregnancy, left ventricular rotation and twist values increase significantly in the 3rd trimester [13,14]. In the evaluation made in terms of the rotation rate, reversed rotation rate increased in the early period of pregnancy and decreased to control values in the last trimester of pregnancy.…”

Objectives: The speckle-tracking technique calculates the regional rate, the strain and the strain rate from twodimensional gray-scale visualizations. The aim of this study was to evaluate with speckle-tracking echocardiography the effects of the first, second and third trimesters of pregnancy on cardiac functions. Methods: One hundred five voluntary pregnant and 35 healthy women of reproductive age were included in the study. For echocardiographic evaluations, the 111 highest-quality visualizations were chosen: 24 cases in the first trimester, 31 cases in the second trimester, 32 cases in the third trimester and 24 healthy women as a control group. Global longitudinal, radial, and circumferential strain, and left ventricular (LV) rotation and twist were evaluated by two-dimensional speckle tracking echocardiography. Results: During pregnancy, the diameter, and volume of the left atrium, LV stroke volume, and the heart rate significantly increased beginning in the first trimester (p < 0.0125). The parameters of pulse-Doppler E velocity and tissue Doppler Em velocity significantly increased in the first trimester (p < 0.0125), whereas in the second and third trimester they decreased to control levels. Global longitudinal strain was significantly decreased in the third trimester of the pregnancy (p < 0.0125). Basal and apical LV rotation and twist were significantly increased in the third trimester of pregnancy (p < 0.0125). LV apical and basal reverse rotation rate were significantly increased in the first trimester of pregnancy (p < 0.0125). Conclusions: In the third trimester global longitudinal strain decreased whereas LV rotation and twist increased. Speckle-tracking echocardiography may be used to evaluate the effects of pregnancy and that provide further data on cardiac functions.

“…First, normative values for strain during pregnancy have not been established, although some studies suggest that strain worsens during the third trimester. 12,13 Average strain rates in our control cohort are similar to those reported in the literature. We aimed to account for pregnancy-related changes in strain by matching on gestational age and other clinical factors, although it was not possible to match on all relevant factors.…”

Women with peripartum cardiomyopathy have normal ejection fraction, but abnormal systolic strain, during pregnancy

et al. 2021

We report a case series of six women with peripartum cardiomyopathy (PPCM) who incidentally underwent echocardiography prior to the clinical presentation of PPCM. For comparison, we identified controls, matched 2:1 on age, race, body mass index, gestational age, and hypertensive disorder. Among the six cases, all were diagnosed with PPCM during the post-partum period. Pre-PPCM echocardiograms were performed between 17.7 weeks of gestation and 13 days post-partum. Baseline left ventricular ejection fraction and size were normal and similar to the 12 matched controls (60% ± 6.6% vs. 61.4% ± 6.3%, P = 0.63) or left ventricular end-diastolic dimension (4.6 cm ± 0.2 cm vs. 4.5 cm ± 0.4 cm, P = 0.689). There was a trend towards a less negative (more abnormal) mean global longitudinal strain in cases compared with controls (À14% ± 4% vs. À18.3% ± 4.5%, P = 0.0658). Mean global circumferential strain was significantly less negative (more abnormal) in cases compared with controls (À21.5% ± 5% vs. À29.3% ± 7.6%, P = 0.0329). We conclude that women who develop PPCM have normal left ventricular ejection fraction during gestation preceding PPCM, indicating that the disease develops acutely in the peripartum period. Abnormal strain can be detected, however, suggesting that strain imaging could represent a screening method in populations at high risk for PPCM if confirmed in future studies.

Evaluation of myocardial viability in patients with acute myocardial infarction

Background:The value of layer-specific two-dimensional speckle tracking echocardiography (LS2D-STE) for evaluating viable myocardium (VM) in patients with acute myocardial infarction (AMI) was unclear, this study provides new insights into it and to make a comparison with dualisotope simultaneous acquisition single photon emission computed tomography ( DISA-SPECT).Methods:Forty hospitalized patients with AMI and left ventricular systolic dysfunction (left ventricular ejection fraction <50%) underwent LS2D-STE and DISA-SPECT before percutaneous coronary intervention (PCI). The longitudinal, circumferential, and radial peak systolic strains and the peak systolic strain rates of 3 myocardiallayers (endocardium, mid-myocardium, and epicardium), as well as the total wall thickness, were determined by LS2D-STE. Routine echocardiography was followedup at 1, 3, 6 months after PCI, with the improvement of the wall motion as the goldenstandard for evaluating VM.Results:The sensitivity, specificity and accuracy of DISA-SPECT for evaluating VM were 82.1%, 74.3%, and 79.3%, respectively. Among the layer-specific parameters, only endocardial (endo-) longitudinal strain (LS) and endo- longitudinal strain rate (LSr) were used as independent parameters for evaluating VM (P < .05), and the sensitivity, specificity and accuracy of endo-LS and endo-LSr in evaluation of VM were 77.1%, 65.4%, and 72.9% vs 72.9%, 65.4%, and 69.7%. Endo-LS and endo-LSr were superior to total wall thickness LS and LSr (AUC endo-LS 0.767 vs total-LS 0.669; endo-LSr 0.743 vs total-LSr 0.682). The parallel test and the serial test of combination of endo-LS and endo-LSr showed similar sensitivity, specificity and accuracy to DISA-SPECT (P > .05).Conclusion:The endo-LS and endo-LSr analysis of LS2D-STE can evaluate the VM well, and its sensitivity, specificity and accuracy in detection of VM are similar to those of DISA-SPECT, resulting in LS2D-STE being a good option for the assessment of VM.
