“…Left atrial strain and strain rate were measured by speckle-tracking echocardiography (STE). We manually traced three markers in the left atrial maximum volume view, acquired the curve of the strain rate and calculated the average value in both the two-chamber and fourchambe viewsr [14]. The images were recorded over three consecutive cardiac cycles with a stable echocardiographic appearance.…”

“…Since LBB is a wide network, implanting the lead to the sub-endoucardium of left septum could easily capture left conduction system [12]. And LBBP has been demonstrated its feasibility and efficacy in LBBB cases with heart failure due to this characteristics [13,14]. The purpose of this study was to use brain natriuretic peptide (BNP), echocardiography and speckle-tracking echocardiagraphy to compare the changes in cardiac function (especially left atrial function, and left ventricular diastolic function) within 7 days between LBBP and RVOP in pacemaker-dependent patients.…”

Background: The novel method of left bundle branch pacing (LBBP) has been reported to produce a narrower QRS duration and lower pacing threshold than right ventricular outflow tract septal pacing (RVOP). However, whether LBBP is superior to traditional RVOP in improving cardiac function still lacks sufficient evidence. Objective: The purpose of this study was to compare the changes in cardiac function (especially in brain natriuretic peptide (BNP)levels, left atrial function, and left ventricular diastolic function) within 7 days between LBBP and RVOP. Methods and results: A single-centre prospective controlled registered clinical study was conducted with 84 patients with bradycardia indications. Forty-two patients underwent RVOP, and 42 patients underwent LBBP. The pacemaker parameters were adjusted so that the ventricular ratio was over 90% and rate was 60-70 bpm. The changes in BNP levels and echocardiogram and speckle-tracking echocardiagraphy findings were compared between the two groups before and within 7 days after implantation: (1) BNP: there was no significant difference in BNP level between the two groups before and 1 day after implantation, while the LBBP group had significantly lower levels than the RVOP group on day 7 [(65.15 ± 56.96)pg/ml vs.(129.82 ± 101.92)pg/ml, P < 0.001].(2) Cardiac echocardiography: the e' value of the LBBP group was higher than that of the RVOP group 7 days after implantation[(6.39 ± 2.65) cm/s vs. (5.45 ± 1.35)cm/s, P = 0.049]. The E/e' and peak E-wave velocity in the LBBP group decreased significantly after 7 days [16.57 ± 6.55 vs. 12.75 ± 5.16 P = 0.043, (88.6 ± 24.37) cm/s vs. (75.68 ± 28.10)cm/s P = 0.030]; in contrast, there were no significant changes in the RVOP group [14.13 ± 3.85 vs.14.10 ± 4.85 P = 0.50, (77.33 ± 21.14)cm/s vs. (74.45 ± 23.03)cm/s P = 0.56). (3)Speckletracking echocardiagraphy: there was no significant difference in left atrial strain or the strain rate between the LBBP and RVOP groups，but the absolute values of left atrial strain and strain rate in the LBBP group increased, while those in the RVOP group decreased. Conclusion:This study demonstrates that compared to RVOP, LBBP can increase left ventricular early diastolic function, improve BNP levels, and has a tendency to increase left atrial myocardial elasticity and left atrial strain capacity in the short term in pacemaker-dependent patients.

“…LA makes a large contribution to LV filling and thus plays an important role in the pathophysiology and progression of cardiovascular disease [5]. Although some studies on maternal LA structure and performance during pregnancy, those reports just focused on the volumetric analysis [16,14] or the adaptive changes during the healthy pregnancy rather than PE pregnant course [14,15]. To the best of our knowledge, this study is the first to demonstrate the LA myocardial deformation and atrial compliance by STE in the patients suffering from PE.…”

“…However, there are few reports about the effects of PE on maternal LA mechanics though some studies described the STE-derived LA deformation parameters in normal pregnancy and the postpartum period [14,15]. In the previous studies, using a real-time three-dimensional echocardiography, we identified the dilated atrial chamber and reduced volumetric action of LA occurring during the course of PE [16].…”

Background: Pre-eclampsia (PE) is a severe obstetric complication associated with many cardiovascular disorders. Left atrial (LA) function and its relevance to the cardiovascular adaptation changes associated with PE have not been adequately addressed. The aim of this study was to quantify LA myocardial deformation characteristics in women with PE using speckle tracking echocardiography (STE). Methods: Using STE, LA global longitudinal strain (LAGLS), phasic LA strain values and LASr/(E/e'), which was the value of LA reservoir strain (LASr) divided by the quotient of early mitral flow velocity (E) and diastolic mitral ring velocity (e'), were compared among nonpregnant controls (n=39), normotensive pregnant women (n=40), and PE (n=43) patients. Results: LAGLS, LASr and LA conduit strain reduced in PE group in spite of no difference of LA contraction strain among the three groups. LASr/(E/e'), the surrogate of LA compliance, was decreased during PE pregnancy. The multivariate regression analyses showed LAGLS was independently correlated with LASr/(E/e'), left ventricular global longitudinal strain and LA maximum volume. Conclusion: PE cases undergo impaired LA myocardial function and decreased atrial compliance. STE-derived LA strain may be a powerful diagnostic parameter to evaluate diastolic function with the progression of PE pregnancy.

“…Because of the increased venous return, the dimension of the left atrium expands. Recently Tasar et al [7] showed that left atrial area and volume increase whereas left atrial strain decrease from the first trimester to the third trimester during pregnancy. LV diameters increased during pregnancy but did not reach significance.…”

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.
