Abstract
BACKGROUND Quantification of left atrial (LA) conduit function and its contribution to left ventricular (LV) filling is challenging because it requires simultaneous measurements of both LA and LV volumes. The functional relationship between LA conduit function and the severity of diastolic dysfunction remains controversial. We studied the role of LA conduit function in maintaining LV filling in advanced diastolic dysfunction. METHODS We performed volumetric and flow analyses of LA function across the spectrum of LV diastolic dysfunction, derived from a set of consecutive patients undergoing multiphasic cardiac computed tomography scanning (n=489). From LA and LV time-volume curves, we calculated 3 volumetric components: (1) early passive emptying volume; (2) late active (booster) volume; and (3) conduit volume. Results were prospectively validated on a group of patients with severe aortic stenosis (n=110). RESULTS The early passive filling progressively decreased with worsening diastolic function (P<0.001). The atrial booster contribution to stroke volume modestly increases with impaired relaxation (P=0.021) and declines with more advanced diastolic function (P<0.001), thus failing to compensate for the reduction in early filling. The conduit volume increased progressively (P<0.001), accounting for 75% of stroke volume (interquartile range, 63-81%) with a restrictive filling pattern, compensating for the reduction in both early and booster functions. Similar results were obtained in patients with severe aortic stenosis. The pulmonary artery systolic pressure increased in a near-linear fashion when the conduit contribution to stroke volume increased above 60%. Maximal conduit flow rate strongly correlated with mitral E-wave velocity (r=0.71; P<0.0001), indicating that the increase in mitral E wave in diastolic dysfunction represents the increased conduit flow. CONCLUSIONS An increase in conduit volume contribution to stroke volume represents a compensatory mechanism to maintain LV filling in advanced diastolic dysfunction. The increase in conduit volume despite increasing LV diastolic pressures is accomplished by an increase in pulmonary venous pressure.

Abstract
Diagnosis of heart failure with preserved ejection fraction (HFpEF) can be challenging and it could require different tests, some of which are affected by limited availability. Nowadays, considering that new therapies are available for HFpEF and related conditions, a prompt and correct diagnosis is relevant. However, the diagnostic role of biomarker level, imaging tools, score-based algorithms and invasive evaluation, should be based on the strengths and weaknesses of each test. The aim of this review is to help the clinician in diagnosing HFpEF, overcoming the diagnostic uncertainty and disentangling among the different underlying causes, in order to properly treat this kind of patient.

J Magn Reson Imaging 2023; 58:1125-1136. [PMID: 36733221 DOI: 10.1002/jmri.28604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 01/04/2023] [Accepted: 01/05/2023] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Mitral regurgitation may occur when hypertension causes left ventricular (LV) and left atrial (LA) remodeling. However, its role in LA function in hypertensive patients remains unclear. PURPOSE To explore how mitral regurgitation affects LA function in hypertension and to investigate atrioventricular interaction in hypertensive patients with mitral regurgitation. STUDY TYPE Retrospective. POPULATION A total of 193 hypertensive cases and 64 controls. FIELD STRENGTH/SEQUENCE A 3.0 T/balanced steady-state free precession. ASSESSMENT LA volume (LAV), LA strain (reservoir, conduit, and active), LA ejection fraction, and LV strain (global peak longitudinal [GLS], circumferential [GCS], and radial strain [GRS]) were evaluated and compared among groups. Regurgitant fraction (RF) was evaluated in regurgitation patients and used to subdivide patients into mild (RF: 0%-30%), moderate (RF: 30%-50%), and severe (RF: >50%) regurgitation categories. STATISTICAL TESTS One-way analysis of variance, Spearman and Pearson's correlation coefficients (r), and multivariable linear regression analysis. A P value <0.05 was considered statistically significant. RESULTS Hypertensive patients without mitral regurgitation showed significantly impaired LA reservoir and conduit functions and significantly decreased LV GLS but preserved pump function and LAV compared to controls (P = 0.193-1.0). Hypertensive cases with mild regurgitation (N = 22) had significantly enlarged LAV and further reduced LA reservoir function, while the group with moderate regurgitation (N = 20) showed significantly reduced LA pump function, further impaired conduit function, and significantly reduced LV strain. The severe regurgitation (N = 13) group demonstrated significantly more severely impaired LA and LV functions and LAV enlargement. Multivariable linear regression showed that regurgitation degree, GRS, GCS, and GLS were independently correlated with the LA reservoir, conduit, and active strain in hypertensive patients with mitral regurgitation. DATA CONCLUSION Mitral regurgitation may exacerbate LA and LV impairment in hypertension. Regurgitation degree, LV GRS, GCS, and GLS were independent determinants of the LA strain in hypertensive patients with mitral regurgitation, which demonstrated atrioventricular interaction. EVIDENCE LEVEL 4. TECHNICAL EFFICACY Stage 3.

Abstract
BACKGROUND AND AIM OF THE STUDY The response to the increase in heart rate (HR) could be characterized by failure in both left ventricular (LV) and left atrial (LA) functions. This study aimed to evaluate the relationship between the increase in paced HR and the changes in LV and LA functions, assessed by two-dimensional speckle tracking analysis. METHODS In a group of patients with an implantable cardioverter defibrillator (ICD) or pacemaker, the atrial paced rhythm was progressively increased from 60 to 70, from 70 to 80, and from 80 to 90 beats per minute (bpm). For each paced HR, using two-dimensional speckle tracking analysis, LA reservoir (LAr), LA conduit (LAc), LA contraction (LAct), and LV global longitudinal strain (LV-GLS) were evaluated every 10 bpm. RESULTS Of the 45 patients enrolled, a significant reduction in LAr was observed at higher HR. However, when the patients were dichotomized according to the HR-related response of LV-GLS, the worsening of LAr was observed in those with LV-GLS worsening and not in those without (maximum LAR absolute changes -2.7 ± 7.2% vs. +2.7 ± 7.2%, respectively, p .028). Moreover, the worsening of LA and LV strain measures was associated with an increase in the estimated filling pressures. CONCLUSIONS In patients with atrial paced rhythm, the increase in HR could be associated with worsening of LA and LV functions, as assessed by two-dimensional speckle tracking analyses. These results offer new data on HR-related atrioventricular function and could be useful for guiding the optimal HR responsiveness of the implanted devices.

Abstract
BACKGROUND Two-dimensional speckle tracking evaluation (2D-STE) is a useful tool to evaluate the complexity of atrial function by the analysis of the different phases of atrial deformation and by the combination with Doppler measurements of diastolic function. AIM OF THE STUDY To evaluate the role of the left atrial (LA) strain parameters to predict worsening chronic heart failure (CHF). METHODS We enrolled outpatients affected by CHF referred to our heart failure unit. Each patient underwent a medical visit, an electrocardiogram (ECG), and an echocardiographic examination. LA function was assessed by 2D-STE. The three phases of LA strain, that is, the reservoir (LAr), the conduit (LAcd), and the contraction (LAct)-were evaluated. Moreover, the ratio between E and LAr (E/LAr) and those between LAr and septal (LAr/Ees), lateral (LAr/Eel), and septal-lateral (LAr/Eem) E/e' were measured. During follow-up, the events related to worsening of heart failure were evaluated. RESULTS Two hundred eleven patients were enrolled. During a mean follow-up of 14 ± 7 months, 37 patients showed at least one event related to heart failure worsening. At univariate Cox regression analysis, LAr, LAcd, LAct, E/LAr, LAr/Ees, LAr/Eel, and LAr/Eem were all associated with events related to heart failure worsening, but at multivariate regression analyses, only LAr (Hazard Ratio, HR: .95; 95% Confidence Interval, CI: .92-.99; p: .031), LAct (HR: 1.06; 95% CI: 1.01-1.12; p: .027), E/LAr (HR: 1.10; 95%CI: 1.0-1.16; p < .001), LAr/Ees (HR: .57; 95% CI: .37-.87; p: .010), and LAr/Eem (HR: .71; 95% CI: .53-.96; p: .026) remained significantly associated with the events. Finally, in a predictive model including the other relevant echocardiographic parameters LAr < 18%, LAct > -10.0%, LAr/Ees < 1.28, and E/LAr > 3.70 were associated with a statistically significant overall net reclassification improvement. CONCLUSIONS In CHF patients, the measure of the LA reservoir and contraction by 2D-STE is independently associated with heart failure worsening, but the accuracy in predicting the events is even greater when the reservoir is combined with the Doppler measures of diastolic function.

The effects of combination treatment with LT4 and LT3 on diastolic functions and atrial conduction time in LT4-treated women with low T3: a short term follow-up study. Endocrine 2023:10.1007/s12020-023-03363-1. [PMID: 37074560 DOI: 10.1007/s12020-023-03363-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Accepted: 03/31/2023] [Indexed: 04/20/2023]
Abstract
PURPOSE To investigate the effects of combination treatment with levothyroxine (LT4) and l- triiodothyronine (LT3) on left atrial volume (LAV), diastolic functions, and atrial electro-mechanical delays in LT4-treated women with low triiodothyronine (T3) levels. METHODS This prospective study consisted of 47 female patients between 18 and 65 years old treated at an Endocrinology and Metabolism outpatient clinic between February and April 2022 due to primary hypothyroidism. The study included patients with persistently low T3 levels in at least three measurements, despite LT4 treatment (1.6-1.8 mcg/kg/m2) for 23.13 ± 6.28 months with normal thyrotropin (TSH) and free tetraiodothyronine (fT4) levels. The combination therapy dose was as follows: the fixed LT4 dose (25 mcg) was removed from patients' usual LT4 treatment [100 mcg (min-max, 75-150)], and a fixed LT3 dose (12.5 mcg) was added. Biochemical samples were taken, and an echocardiographic assessment was performed for patients upon their first admission, and after 195.5 ± 12.8 days of receiving LT3 (12.5 mcg) treatment. RESULTS There was a statistically significant reduction at left ventricle (LV) end-systolic diameter (27.69 ± 3.14, 27.13 ± 2.89, p = 0.035), left atrial (LA) maximum volume (14.73 ± 3.22, 13.94 ± 3.15, p = 0.009), LA minimum volume (7.84 ± 2.45, 6.84 ± 2.30, p < 0.001), LA vertical diameter (44.08 ± 6.92, 34.60 ± 4.31, <0.001), LA horizontal diameter (45.65 ± 6.88, 33.43 ± 4.51, p < 0.001), LAVI (50.73 ± 18.62, 41.0 ± 13.02, p < 0.001), total conduction time (103.69 ± 12.70, 79.82 ± 18.40, p < 0.001) after LT3 replacement (respectively pre-post- treatment and p value). CONCLUSION In conclusion, the findings of this study suggest that the addition of LT3 to LT4 treatment may lead to improvements in LAVI and atrial conduction times in patients with low T3. However, further research with larger patient groups and exploration of different LT4 + LT3 dose combinations is needed to better understand the effects of combined hypothyroidism treatment on cardiac functions.

Abstract
PURPOSE To evaluate left atrial (LA) function in patients with hypertrophic cardiomyopathy (HCM) by LA strain assessment using cardiac computed tomography (CT-derived LA strain). MATERIALS AND METHODS This was a retrospective study of 34 patients with HCM and 31 non-HCM patients who underwent cardiac computed tomography (CT) using retrospective electrocardiogram-gated mode. CT images were reconstructed every 5% (0-95%) of the RR intervals. CT-derived LA strain (reservoir [LASr], conduit [LASc], and booster pump strain [LASp]) were semi-automatically analyzed using a dedicated workstation. We also measured the left atrial volume index (LAVI) and left ventricular longitudinal strain (LVLS) for the left atrial and ventricular functional parameters to assess the relationship with CT-derived LA strain. RESULTS CT-derived LA strain significantly correlated with LAVI: r = - 0.69, p < 0.001 for LASr; r = - 0.70, p < 0.001 for LASp; and r = - 0.35, p = 0.004 for LASc. CT-derived LA strain also significantly correlated with LVLS: r = - 0.62, p < 0.001 for LASr; r = - 0.67, p < 0.001 for LASc; and r = - 0.42, p = 0.013 for LASp. CT-derived LA strain in patients with HCM was significantly lower than that in non-HCM patients: LASr (20.8 ± 7.6 vs. 31.7 ± 6.1%, p < 0.001); LASc (7.9 ± 3.4 vs. 14.2 ± 5.3%, p < 0.001); and LASp (12.8 ± 5.7 vs. 17.6 ± 4.3%, p < 0.001). Additionally, CT-derived LA strain showed high reproducibility; inter-observer correlation coefficients were 0.94, 0.90, and 0.89 for LASr, LASc, and LASp, respectively. CONCLUSION CT-derived LA strain is feasible for quantitative assessment of left atrial function in patients with HCM.

Role of Echocardiography in Diabetic Cardiomyopathy: From Mechanisms to Clinical Practice. J Cardiovasc Dev Dis 2023; 10:jcdd10020046.

Abstract
It has been well established that diabetes mellitus (DM) is considered as a core risk factor for the development of cardiovascular diseases. However, what is less appreciated is the fact that DM may affect cardiac function irrespective of cardiac pathologies to which it contributes, such as coronary artery disease and hypertension. Although echocardiography provides accurate and reproducible diagnostic and prognostic data in patients with DM, its use in these patients is still underappreciated, resulting in progression of DM-related heart failure in many patients. Hence, in the present review, we aimed to discuss the role of echocardiography in the contemporary management of diabetic cardiomyopathy (DCM), as well as the role of emerging echocardiographic techniques, which may contribute to earlier diagnosis and more appropriate management of this complication of DM. In order to improve outcomes, focus must be placed on early diagnosis of this condition using a combination of echocardiography and emerging biomarkers, but perhaps the more important thing is to change perspective when it comes to the clinical importance of DCM.

Abstract
Objective: Atrial fibrillation is a strong independent risk factor for cardioembolic stroke, with a significant impact on morbidity, mortality and healthcare costs. The aim of our study is to investigate left atrial mechanical function in healthy subjects and patients with atrial fibrillation paroxysms less than 48 hours with low risk of thromboembolic complications at 1 and 28 days after restoration of sinus rhythm.
Methods: Thirty-six healthy controls and patients with paroxysms of non-valvular atrial fibrillation less than 48 hours (n=25) with low-risk CHA2DS2VASc score were included in the study. The mechanical function of the left atrium (LA) was investigated by the 2D speckle tracking program. Transthoracic echocardiography was performed on the 1st and 28th days after restoration of sinus rhythm by pharmacological cardioversion.
Results: Despite the absence of differences in left ventricular systolic function and LA size between the groups, there was a significant decrease in LA deformation and strain rate on day 1 immediately after sinus rhythm recovery in the patients. In the pump phase, the decrease was about 3%, reservoir phase – 10%, and conduit phase – 7% compared to the control group. The strain rate also decreased in the patient group: -1.5 s-1 versus control: -2.14 s-1 (p<0.0001). On the 28th day after restoration of sinus rhythm, there were significant changes in reservoir and conduit functions in patients group in comparison with control group. Global longitudinal LA strain (reservoir phase) decreased to 7%, conduit phase decreased to 11% compared with the control group. In patients group we can see the dynamics during 28 days: pump phase and strain rate were significantly improved, however reservoir and conduit did not significantly change and were lower than in healthy.
Conclusion: Mechanical function of the LA in patients with non-valvular atrial fibrillation and low risk of thromboembolic complications, studied with speckle tracking on the first day was significantly impaired compared with the control group (reservoir phase and strain rate). By day 28, mechanical function improved compared to day 1, but reservoir phase remained significantly lower than normal.

Quantitative assessment of left atrial functions by speckle tracking echocardiography in hypertensive patients with and without retinopathy. JOURNAL OF CLINICAL ULTRASOUND : JCU 2022; 50:759-768.

Abstract
PURPOSE The association between hypertensive retinopathy and left atrial (LA) impairment is unknown. Accordingly, it was aimed to investigate the possible relationship between hypertensive retinopathy and LA phasic functions by means of two-dimensional speckle-tracking echocardiography (2D-STE). METHODS A total of 124 hypertensive patients and 27 control subjects were included in the study. LA reservoir strain (LAS-S ), LA conduit strain (LAS-E ), and LA booster strain (LAS-A ) parameters were used to evaluate LA myocardial functions. RESULTS Hypertensive patients (with and without retinopathy) displayed an obvious reduction in the LA reservoir strain (LAS-S ), and LA conduit strain (LAS-E ). Moreover, further impairment in LA reservoir and conduit strain was found in patients with hypertensive retinopathy than in the isolated hypertensive patients. There were no significant differences in LA booster strain (LAS-A ) among the three groups. Impaired LAS-S (OR: 0.764, CI: 0.657-0.888, and p < 0.001), LAS-E (OR: 0.754, CI: 0.634-0.897, and p = 0.001), and hypertension (HT) duration (OR: 2.345, CI: 1.568-3.507, and p < 0.001) were shown to be independent predictors of hypertensive retinopathy. CONCLUSION Impaired LA reservoir and conduit strain may be used to predict hypertensive patients at higher risk of developing hypertensive retinopathy, and to determine which patients should be followed more closely for hypertensive retinopathy.

Abstract
Hypertension is associated with the development of atrial fibrillation (AF). Evidence has shown that reverse dipping pattern, an abnormal increase of night-time blood pressure (BP) comparing to daytime BP, is associated with cardiovascular events. However, the relationship between diurnal changes in BP and AF has not been sufficiently explored. This paper aims to cross-sectionally explore the relationship between AF and ambulatory BP parameters, especially reverse dippers to the others, and further longitudinally analyze how BP patterns are associated to the risk of developing new-onset AF. Between February 2012 and March 2021, five out of 412 patients were identified of AF at baseline; four were reverse dippers (3.7%) and one was from the others (.3%). Cross-sectionally, the multivariate logistic regression analysis showed that reverse dippers were significantly more likely to have AF (odds ratio: 12.39, p = .030). After excluding patients with baseline AF, during the mean follow-up of 4.6 ± 3.0 years, seven patients developed AF. Longitudinally, the multivariate Cox regression analysis revealed that 24-h systolic BP (hazard ratio per 10 mmHg: 2.12, p = .015), night-time systolic BP (hazard ratio per 10 mmHg: 2.27, p = .002), and presentation of reverse dipping (hazard ratio: 5.25, p = .042) were independently associated with new-onset AF. None of the office BP measurements were associated with new-onset AF. While ambulatory BP measurements were better predictors for the incidence of AF, careful management is necessary for reverse dippers as they are at high risk of developing AF.

Abstract
Objective: The coexistence of type 2 diabetes (T2D) and heart failure (HF) has obvious consequences during cardiovascular diagnosis. This study evaluated the relationship between T2D and clinical and echocardiographic features of patients with HF. Methods & results: 121 patients with HF were clinically evaluated by echocardiography in this case-control study. They were divided into two groups based on the presence of T2D. Patients with diabetes were subdivided and compared via an HbA1c control. Significant differences between T2D and non-T2D groups were detected by comparing the left atrial diameter, E/E' and left ventricular end-diastolic diameter. When comparing patients with diabetes, differences in acute heart failure episodes, left ventricular ejection fraction, left atrial diameter and E/E' were evaluated. Conclusion: T2D was associated with important cardiac alterations and more severe HF. Poor control of diabetes resulted in worse cardiovascular outcomes.

Abstract
Background Evidence of diastolic dysfunction (DD) required for the diagnosis of heart failure with preserved ejection fraction (HFpEF) is elusive in atrial fibrillation (AF). Left ventricular (LV) and left atrial (LA) speckle-tracking echocardiography (STE) may provide rhythm independent indications of DD. We aimed to find common LV/LA myocardial mechanics parameters to demonstrate DD, using STE in patients with AF. Methods 176 echocardiographic assessments of patients were studied retrospectively by STE. 109 patients with history of AF were divided in three groups: sinus with normal diastolic function (n = 32, ND), sinus with DD (n = 35, DD) and patients with AF during echocardiography (n = 42). These assessments were compared to 67 normal controls. Demographic, clinical, echocardiographic and myocardial mechanic characteristics were obtained. Results The patients with DD in sinus rhythm and patients with AF were similar in age, mostly women, and had cardiovascular risk factors as well as higher dyspnea prevalence compared to either controls or patients with ND. In the AF group, LV ejection fraction (LVEF) (p = 0.008), global longitudinal strain and LA emptying were lower (p < 0.001), whereas LA volumes were larger (p < 0.001) compared to the other groups. In a multivariable analysis of patients in sinus rhythm, LA minimal volume indexed to body surface area (Vmin-I) was found to be the single significant factor associated with DD (AUC 83%). In all study patients, Vmin-I correlated with dyspnea (AUC 80%) and pulmonary hypertension (AUC 90%). Conclusions Vmin-I may be used to identify DD and assist in the diagnosis of HFpEF in patients with AF.

Abstract
BACKGROUND Cardiotoxicity has become a significant adverse effect of cancer therapy, with Anthracyclines (ANT) in particular. There is a crucial need for new imaging techniques for the early subclinical detection of cardiotoxic effect. We aimed to evaluate left atrial strain (LAS) changes during ANT therapy and to assess the correlation between LAS and the routine echocardiographic diastolic parameters. METHODS AND RESULTS Data were prospectively collected as part of the Israel Cardio-Oncology Registry (ICOR). All female patients with breast cancer, planned for ANT therapy were included. All patients underwent serial echocardiography exams including baseline LAS (before chemotherapy, T1) and shortly after the completion of ANT therapy (T3). LAS was assessed in 3 phases: Reservoir (LASr), Conduit (LASc) and Pump (LASp). Significant reduction in LASr was determined by either a relative reduction of >10% or an absolute value of <35%. From September 2016 to June 2019, 40 patients were evaluated with a mean Doxorubicin (type of ANT) dose of 237±13.24mg/m2. At T3, significant reduction in LASr was observed among 50% of the patients with a mean LASr reduction from 40.15 ± 6.83% to 36.04 ± 7.73% (p < 0.001). LASc showed significant reduction as well (p < 0.004) as opposed to LASp (p=0.076). Both LASr and LASc showed significant correlation to the routine diastolic parameters. CONCLUSIONS LASr and LASc reduction are frequent and occur early in the course of ANT therapy, showing significant correlation to the routine echocardiographic diastolic parameters, which may imply a role in the detection of early cardiotoxicity.

Abstract
Aim A predictive model using left atrial function indexes obtained by real‐time three‐dimensional echocardiography (RT‐3DE) and the blood B‐type natriuretic peptide (BNP) level was constructed, and its value in predicting recurrence in patients with early persistent atrial fibrillation (AF) after radiofrequency ablation was explored. Methods A total of 228 patients with early persistent AF who were scheduled to receive the first circular pulmonary vein ablation (CPVA) were enrolled. Clinical data of patients were collected: (1) The blood BNP level was measured before radiofrequency ablation; (2) RT‐3DE was used to obtain the left atrial (LA) time‐volume curve; (3) The clinical characteristics, BNP level and LA function parameters were compared, and logistic regression was used to construct a prediction model with combined parameters; (4) The receiver operating characteristic (ROC) curve was used to examine the diagnostic efficacy of the model. Results (1) 215 patients with early persistent AF completed CPVA and the follow‐up. After 3–6 months of follow‐up, the patients were divided into sinus rhythm group (160 cases) and recurrence group (55 cases); (2) The recurrence group showed higher minimum LA volume index, diastolic ejection index, and preoperative BNP (all p ≤ .001), while the sinus rhythm group exhibited higher expansion index (PI) and left atrial appendage peak emptying velocity (p ≤ .001); (3) In univariate analysis, BNP level had the best diagnostic performance in predicting the recurrence of AF(AUC = 0.703). We constructed a model based on LA function and BNP level to predict the recurrence of persistent AF after CPVA. This combined model was better than BNP alone in predicting the recurrence of persistent AF after CPVA (AUC: 0.814 vs. 0.703, z = 2.224, p = .026). Conclusion The combined model of LA function and blood BNP level has good predictive value for the recurrence of early persistent AF after CPVA.

Abstract
Fontan patients rely on atrial function for diastolic filling and to augment cardiac output. Emerging data suggests that diminished atrial function is predictive of poor outcomes in adults but studies evaluating the association between atrial mechanics in Fontan patients and outcomes are lacking. We sought to assess atrial function in Fontan patients using speckle tracking echocardiography to determine whether atrial function is associated with invasive hemodynamics and clinical outcomes. Single-center review of Fontan patients receiving both catheterization and echocardiogram from 2012-2017. Atrial reservoir, conduit and pump global longitudinal strain and strain rate were assessed by speckle tracking echocardiography. The primary outcome was a composite of all adverse clinical outcomes including cardiac hospitalizations, transplant and death. Eighty-three Fontan patients at a median age of 14.2 years (IQR 8.6, 21.7) at time of echocardiogram were included. Increased atrial reservoir strain (p = 0.04), atrial emptying fraction (p = 0.04) and atrial fractional area change (p = 0.04), were associated with higher cardiac index at baseline. There were no associations between atrial strain and systemic ventricular end diastolic pressure (EDP) at catheterization. Reservoir strain was inversely associated with the composite clinical outcome on multivariable Cox proportional hazard analysis (HR 0.96, p = 0.03). Reduced atrial function is associated with reduced cardiac index, but is not directly associated with ventricular EDP in Fontan patients. Reservoir strain is associated with an excess of adverse clinical outcomes in Fontan patients.

Abstract
OBJECTIVE Left ventricular diastolic dysfunction (LVDD) is very common among patients undergoing cardiac surgery and is associated with increased mortality and morbidity. The present study tested the hypothesis of whether left atrial strain (LAS) can be used as a single parameter to predict LVDD (per 2016 LVDD evaluation guidelines) and elevated left ventricular filling pressure (LVFP) (ie, LVDD grades II and III) in patients scheduled for off-pump coronary artery bypass grafting (OPCABG) surgery. DESIGN A prospective observational study. SETTINGS Tertiary-care level hospital. PARTICIPANTS The study comprised 60 patients undergoing elective OPCABG. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Transthoracic echocardiography was performed within 24 hours of surgery by an anesthesiologist. LVDD was graded per American Society of Echocardiography/European Association of Cardiovascular Imaging recommendations for 2016 LVDD guidelines. Left atrial (LA) function was evaluated using two-dimensional strain measurements obtained with the speckle-tracking echocardiography technique. Receiver operating characteristic curves were constructed, and the area under the curve was derived for the prediction of elevated LVFP by LAS. Fourteen (23.3%) patients had elevated LVFP. Global LA reservoir strain (LASr) reduced significantly as the LVDD grade worsened (28.9% ± 8.3%, 21.8% ± 7.2%, 15.6% ± 4.5% and 11.9% ± 1.3%, respectively, for normal LV diastolic function and grades I, II, and III LVDD; p < 0.0001). Similar trends were noted for other components of LAS; namely, global LA conduction, global LA contraction strain, and LAS rate. The ability to predict high LVFP with LASr was statistically significant, with an area under the receiver operating characteristic curve of 0.92 (confidence interval 0.82-0.97; p < 0.001), and a Youden's index for LASr of 19% was obtained with 85.71% sensitivity and 84.78% specificity. The ability of LAS and its components to predict increased LVFP in various subpopulations (normal v reduced ejection fraction) yielded statistically significant results. CONCLUSIONS In patients scheduled for OPCABG, cardiac anesthesiologists successfully could measure LAS with speckle-tracking echocardiography in the preoperative period. LAS as a single parameter was significantly associated with the grade of LVDD. LASr decreased significantly with worsening grade of LVDD. Furthermore, an LASr value <19% significantly predicted a high LVFP, and LASr predicted high LVFP in both preserved and reduced ejection fraction equally well.

The Influence of Atrial Strain on Functional Capacity in Patients with the Fontan Circulation. Pediatr Cardiol 2020; 41:1730-1738. [PMID: 32770389 DOI: 10.1007/s00246-020-02435-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2020] [Accepted: 08/04/2020] [Indexed: 12/22/2022]
Abstract
Speckle-tracking echocardiography has been used to assess atrial function. This analysis is feasible in univentricular hearts. The aim of this study was to characterize the relationship between atrial strain and functional capacity in the Fontan circulation. Apical four-chamber echocardiographic loops of 39 Fontan patients were reviewed. The dominant atrium was assessed for active (εact), conduit (εcon), and reservoir (εres) strain and εact/εres ratio. Cardiopulmonary exercise test was performed on the same day and oxygen uptake (VO2) at ventilatory threshold (VT) and peak VO2 were chosen as the dependent variables. Statistical analysis was performed using SPSS® version 23. Unpaired t test was used for binomial and continuous variable correlation; single and multivariable linear regression were used for continuous variable correlation. Statistical significance was defined as p value < 0.05. VO2 at VT as a percentage of predicted VO2 was 36.8% (SD 10.7). Peak VO2 was 64.7% (SD 18.9) of the predicted value. In univariate analysis, both were associated with age, atrioventricular regurgitation, ejection fraction, εres, εcon, and εact/εres. In multivariate regression, higher VO2 at VT and peak VO2 were associated with younger age (p = 0.003 and p = 0.001, respectively) and higher εcon (p = 0.026 and p = 0.020). Evaluation of heart function is difficult in the Fontan circulation, hindered by complex ventricular morphology and lack of normative data. VO2 provides a good surrogate. Atrial strain parameters are compromised in these patients and associated with VO2. Therefore, whenever possible, atrial strain should be measured as it may provide a new method of risk stratification.

Abstract
OBJECTIVE The purpose of this study was to evaluate the different components of left atrial (LA) dysfunction predictors in asymptomatic primary systemic hypertension patients with preserved left ventricular (LV) ejection fraction, particularly using LA 4-dimensional (4D) longitudinal and circumferential strain values. METHODS AND RESULTS Patients with no left ventricular hypertrophy (NLVH) and left ventricular hypertrophy (LVH) are all asymptomatic regarding primary blood hypertension. Thirty NLVH patients and 30 LVH patients according to LV mass index and 40 controls analyzed by 4D echocardiography were prospectively enrolled. LA volumes and longitudinal and circumferential strains were measured using 4D volume-strain echocardiography with a Vivid E95 Version 203 instrument. Correlation analysis indicated a significant relation between LV 4D mass index and LA 4D longitudinal/circumferential strain (r = -0.446 to 0.381, p = 0.000-0.042). LVH patients had a reduced LA emptying fraction compared with NLVH patients and control subjects (p < 0.01). NLVH patients had an impaired LA conduit function and increased contractile function compared with the control group (p < 0.01). LVH patients had increased LA volumes and significantly decreased reservoir, conduit and contractile functions compared with the controls (p < 0.01). LVH patients had increased LA volumes and decreased reservoir and contractile functions compared with NLVH patients (p < 0.01). The clinical utility of LA 4D volume-strain measurement was verified by receiver-operating characteristic curve analysis showing larger net benefits as evaluated with NLVH, LVH and control group comparisons. Interclass correlation coefficients of interobserver and intraobserver assessments in the LV and LA 4D value evaluations were >0.75 and >0.85, respectively. CONCLUSIONS LVH patients showed increased LA volumes and decreased LA emptying fractions. LA reservoir, conduit and contractile functions were significantly impaired in LVH patients. Decreased LA conduit function and increased contractile function were revealed in NLVH patients. LA volumetric and functional analyses with 4D volume-strain echocardiography may facilitate the recognition of subtle LA and LV dysfunctions in asymptomatic systemic hypertension patients.

Abstract
Background Data is limited on baseline left atrial (LA) myocardial mechanics between apical hypertrophic cardiomyopathy (ApHCM) patients who develop non-valvular atrial fibrillation (NVAF) during follow-up and those who do not. Methods This retrospective study investigated the clinical outcomes of consecutive patients newly diagnosed with ApHCM between August 2011 and July 2014 who were followed-up for at least 3 years. The patients underwent 12-lead surface electrocardiography and/or 24-hour Holter electrocardiography at least once a year. The patients were divided into two groups, namely those who did or did not exhibit NVAF during follow-up, respectively. The baseline clinical and echocardiographic data of the two groups were compared. Results Twenty patients were studied, five of whom were lost to follow-up. Of the remaining 15 ApHCM patients, seven developed NVAF. No differences were observed in the clinical characteristics of the two groups. However, for the echocardiographic data, the NVAF development group exhibited a larger LA volume and impaired LA reservoir, conduit and booster functions. The NVAF development group also showed lower peak LA strain and stiffer left atrium. The LA volume, function, global strain and stiffness were all statistically associated with NVAF development. Among these parameters, a LA conduit function of ≤ 24.9% was found to be the best parameter to discriminate NVAF development. Conclusions The baseline LA function was impaired in the ApHCM patients who subsequently developed NVAF during follow-up. A LA conduit function of ≤ 24.9% was strongly associated with NVAF development.

Abstract
BACKGROUND Left atrial (LA) strain is a novel parameter of LA function. However, its reference value has not been established, and the determining factors for LA strain remain elusive. We aimed to present LA strain with reservoir, conduit, and contractile components and associated parameters in a large-sized group of healthy individuals. METHODS The present study was from a prospective multicenter registry in South Korea. Subjects who had no history of cardiovascular disease with adequate images were eligible for inclusion. LA reservoir, conduit, and contractile strains (LASRES, LASCD and LASCT, respectively) were measured. Left ventricular global longitudinal strain (LV GLS) and early and late diastolic strain rates (DSRe and DSRa, respectively) were also evaluated. RESULTS Among a total of 324 subjects (mean age: 49 ± 16 years, 167 females), the mean LASRES, LASCD, and LASCT values were 35.9% ± 10.6%, 21.9% ± 9.3%, and 13.9% ± 3.6%, respectively. Mean LV GLS was -20.4% ± 2.2%, and mean DSRe and DSRa were 1.6 ± 0.4 s-1 and 0.8 ± 0.3 s-1, respectively. With aging, LASRES and LASCD showed significant decreases. Factors showing independent associations with LASRES were age (B = -0.425, p < 0.001), DSRe (B = 4.706, p = 0.001), and LV GLS (B = -1.081, p < 0.001). Age (B = -0.319, p < 0.001), DSRe (B = 4.140, p = 0.002), DSRa (B = -3.409, p = 0.018), and LV GLS (B = -0.783, p < 0.001) showed associations with LASCD. With LASCT, only DSRa showed a correlation (R = 0.277, p < 0.001). CONCLUSIONS We presented LA strain in a large-sized group of healthy subjects. Age is a significant determinant of LA function. Associations of LA strain with diastolic strain rates and LV GLS reflect cardiac mechanics.

Abstract
BACKGROUND This study was performed to determine whether strain can supplement the ability of left ventricular (LV) ejection fraction (LVEF) to predict postoperative ventricular dysfunction in patients undergoing mitral valve surgery for degenerative mitral regurgitation (DMR). METHODS From 2004 to 2017, 520 patients with an LVEF of 60% or more underwent mitral valve surgery (98% repair) for DMR. All patients had preoperative, predischarge, and follow-up (mean, 5.0 ± 3.6 years) echocardiograms. Speckle tracking was performed in 119 of 520 patients (22.9%) to determine LV strain, right ventricular free-wall strain, and left atrial longitudinal strain. Multivariate logistic and Cox regression models were used in this subgroup to evaluate associations with early postoperative LV dysfunction and medium-term overall survival, respectively. RESULTS Median preoperative LVEF of the entire cohort was 65%. Based on predischarge echocardiogram, 449 patients (86.3%) maintained postoperative LVEF of 50% or greater. Seventy-one patients (13.7%) had a predischarge LVEF of less than 50%, 49 (9.4%) had a predischarge LVEF of 40% to 49%, and 22 (4.2% overall) had a predischarge LVEF of less than 40%. Abnormal preoperative LV, right ventricular, and left atrial strain measurements were significantly associated with the development of postoperative LV dysfunction, but preoperative hemodynamic and non-strain echo parameters did not vary enough in absolute values to be clinically useful as predictors of postoperative LV dysfunction. CONCLUSIONS Preoperative strain measurements in DMR patients were significantly associated with superior capabilities of detecting underlying LV dysfunction despite preserved preoperative LVEF. Strain analysis may serve as another marker for optimal timing of surgical intervention in DMR patients.

Abstract
AIMS Heart failure (HF) with mid-range ejection fraction (HFmrEF) shares similar diagnostic criteria to HF with preserved ejection fraction (HFpEF). Whether left atrial (LA) function differs between HFmrEF and HFpEF is unknown. We, therefore, used 2D-speckle-tracking echocardiography (2D-STE) to assess LA phasic function in patients with HFpEF and HFmrEF. METHODS AND RESULTS Consecutive outpatients diagnosed with HF according to current European recommendations were prospectively enrolled. There were 110 HFpEF and 61 HFmrEF patients with sinus rhythm, and 37 controls matched by age. LA phasic function was analysed using 2D-STE. Peak-atrial longitudinal strain (PALS), peak-atrial contraction strain (PACS), and PALS-PACS were measured reflecting LA reservoir, pump, and conduit function, respectively. Among HF groups, most of left ventricular (LV) diastolic function measures, and LA volume were similar. Both HF groups had abnormal LA phasic function compared with controls. HFmrEF patients had worse LA phasic function than HFpEF patients even among patients with LA enlargement. Among patients with normal LA size, LA reservoir, and pump function remained worse in HFmrEF. Differences in LA phasic function between HF groups remained significant after adjustment for confounders. Global PALS and PACS were inversely correlated with brain natriuretic peptide, LA volume, E/A, E/e', pulmonary artery systolic pressure, and diastolic dysfunction grade in both HF groups. CONCLUSION LA phasic function was worse in HFmrEF patients compared with those with HFpEF regardless of LA size, and independent of potential confounders. These differences could be attributed to intrinsic LA myocardial dysfunction perhaps in relation to altered LV function.

Abstract
BACKGROUND Severe pulmonary arterial hypertension (sPAH) results in a dilated and dysfunctional right ventricle (RV) together with a small left ventricle (LV) with preserved systolic function. RV size and function parameters have an established association with poor prognosis in sPAH. We sought to determine the impact of RV geometry and function on LV mechanics and its relationship with mortality. METHODS We studied 114 patients (54 ± 13 years) with sPAH, normal LV ejection fraction (LVEF), and complete two-dimensional transthoracic echocardiograms (TTE) and compared them with 70 normal controls of similar age and gender distribution. TTE measurements of atrial sizes, ventricular volumes and function, tricuspid and mitral regurgitation (TR, MR), and LV diastolic function were performed. Speckle-tracking strain was measured in all four chambers, including LV global longitudinal strain (GLS). Cox proportional hazards regression with forward selection was performed to determine the associations between measured indices and mortality over a 20-month follow-up period. Kaplan-Meier curves were generated for variables most associated with death. RESULTS Compared with controls, sPAH patients had greater TR severity and right-chamber size with worse function. Of note, LVEF was normal in both groups. Left atrial peak strain and LV GLS were reduced in sPAH, with greater reductions in nonsurvivors. In multivariate analysis, right atrial volume index (hazard ratio [HR] = 1.02 [CI, 1.01-1.04], P < .01), RV free-wall strain (HR = 1.08; CI [1.01-1.15]; P = .03), and LV GLS (HR = 1.11 [CI, 1.01-1.22]; P = .04) were independently associated with mortality. CONCLUSIONS Although PAH is predominantly a right heart disease, in our cohort of sPAH with normal LVEF, LV GLS was independently associated with death in addition to RV and right atrial abnormalities. These findings indicate that the role of left heart dysfunction in sPAH may be underappreciated in clinical practice.

[PMID: 30729587 DOI: 10.1111/echo.14226] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2018] [Revised: 11/11/2018] [Accepted: 11/15/2018] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND Septal myectomy relieves left ventricular outflow obstruction (LVOTO) and is associated with excellent long-term outcomes. LVOTO is associated with diastolic dysfunction and increased left atrial (LA) size. We sought to investigate the changes in LA volumes and function postmyectomy and the association between these changes with clinical outcomes postmyectomy. METHODS Sixty-six hypertrophic cardiomyopathy patients undergoing myectomy were retrospectively studied. Preprocedural and 6- to 18-month postmyectomy follow-up transthoracic echocardiographic images were obtained. LA volumes and strain were assessed by two-dimensional speckle-tracking echocardiography. RESULTS Left atrial volumes, that is, indexed maximal, minimal, and pre-A volumes reduced postmyectomy, yet remained increased compared to controls (105.6 ± 34.5 mL vs 84.9 ± 26.7 mL, 45.2 ± 25.7 mL vs 35.4 ± 22.6 mL, 70.1 ± 31.4 mL vs 35.4 ± 22.6 mL, respectively, P < 0.05). The total emptying index did not improve postmyectomy and remained lower than controls (58.6 ± 12.4 vs 59.9 ± 12.8, P = NS) whereas atrial contraction improved, yet did not normalize (active emptying index 36.1 ± 14.9 vs 41.1 ± 16.2, P < 0.05). The conduit volume remained reduced postmyectomy (18.6 ± 13.3 mL vs 16.6 ± 15.1 mL, P = NS). LA strain also did not improve postmyectomy (26.8 ± 7.3 vs 28.5 ± 8.8, P = NS). A multivariable logistic regression identified preprocedural E/e' ratio and indexed maximal LA volume, as independent predictors for LA volume reduction ≥20% postmyectomy. During a mean follow-up of 4.9 ± 2.3 years postmyectomy, 24.2% of the patients developed atrial fibrillation and <5% of patients were severely symptomatic. We found no associations between LA volumes/function and atrial fibrillation or symptoms postmyectomy. CONCLUSION Postmyectomy LA volumes decreased, and the contractile function improved. There was no association between LA volumes/function and clinical outcomes postmyectomy. Notably, the LA remained enlarged (though to a lesser degree) with reduced strain and emptying fraction, suggesting possible atrial myopathy.

Abstract
INTRODUCTION Left atrial (LA) size and function are associated with outcome after myocardial infarction (MI). In this study we aimed to assess the impact of LA function as a predictor of exercise capacity through speckle tracking echocardiography. METHODS A total of 94 patients (mean age 54.8±11.0 years; 82% male) were enrolled one month after MI. Echocardiography was used to assess LA volumes and various indices of LA conduit, contraction and reservoir function. LA deformation was assessed by two-dimensional speckle tracking to calculate strain and strain rate at different phases of the cardiac cycle. Exercise capacity was assessed by oxygen uptake (VO2) on cardiopulmonary exercise testing. RESULTS Increased LA volumes, especially LA volume before atrial contraction, were correlated with reduced peak VO2 and reduced VO2 at anaerobic threshold. Decreased peak VO2 was associated with reduced LA conduit function (ρ=0.24; p=0.02), but not with LA booster function (ρ=-0.07; p=0.53). Lower peak atrial longitudinal strain was associated with worse exercise capacity (ρ=0.24; p=0.02). CONCLUSIONS After MI, increased LA volumes were markers of decreased functional capacity that was associated with decreased LA conduit function, but not with LA contractile function. In these patients, LA longitudinal strain analysis may be useful to predict reduced exercise capacity.

Abstract
Background Decreased left atrial (LA) reservoir function is reported to be associated with elevated left ventricular (LV) end diastolic pressure and LV diastolic dysfunction. Echocardiographic parameters that reflect LA reservoir function include LA total emptying fraction [(maximum LA volume - minimum LA volume) / maximum LA volume], peak LA longitudinal strain (PLALS) at systole, and LA stiffness index (E/E´/PLALS). We aimed to investigate the long-term outcomes of LV diastolic function in children with a history of Kawasaki disease (KD) (KDHx group) by assessing LA reservoir function. Methods Retrospectively, echocardiograms performed at a mean follow-up period of 5 years after the acute phase of KD in 24 children in the KDHx group were compared to those from 20 normal control subjects. LA total emptying fraction, PLALS, LA stiffness index, LV peak longitudinal systolic strain (ε), and strain rate (SR) were evaluated with conventional echocardiographic parameters. Results The mean age at long term follow-up echocardiography in children in the KDHx group was 6.8 years. Five children (20.8%) had coronary artery lesions (CALs) in the acute stage of KD. No children showed CALs at a mean follow-up period of 5 years after the acute phase of KD. There were no significant differences in the conventional echocardiographic parameters and in LA total emptying fraction, PLALS, LA stiffness index, LV peak longitudinal systolic ε, and SR, between the children in the KDHx and control group. Conclusion LV diastolic function assessed by LA reservoir function parameters at long-term follow-up in children in the KDHx group appears to be favorable.

Abstract
OBJECTIVE The aim of this study was to comprehensively investigate left atrial (LA) reservoir, conduit, and booster pump functions, as well as their predictors in patients with primary systemic arterial hypertension (HTN) and left ventricular (LV) hypertrophy. METHODS Thirty patients with HTN and LV hypertrophy, but no history of atrial arrhythmia or heart failure, were compared with 29 normotensive controls. Speckle-tracking echocardiography of the LA wall was used to measure systolic and diastolic strains and strain rates. Early diastolic velocity of transmitral flow/early diastolic mitral annular motion velocity (E/E')/peak systolic LA strain (S-LAs) was used as an index of LA stiffness. RESULTS HTN patients had higher LV mass index, impaired LV diastolic function, and higher LA volume index than controls. LA reservoir, conduit, and booster pump functions were significantly lower and LA stiffness was greater. Multiple regression analysis indicated that increased LV mass and LV filling pressures as well as reduced LV strain or E' were predictors for reduced atrial function. CONCLUSION HTN patients showed a significant impairment of the three components of LA function. These changes were correlated with LV hypertrophy and dysfunction, and presumably related to LA fibrotic changes, underlining the importance of LA-LV coupling. The prognostic value of these new speckle-tracking echocardiography-based LA strain indices needs to be evaluated by future studies.

Abstract
The fundoscopic examination of hypertensive patients, which is established hypertension-related target organ damage (TOD), tends to be underutilized in clinical practice. We sought to investigate the relationship between retinal alterations and left atrium (LA) volumes by means of real-time three-dimensional echocardiography (RT3DE). Our population consisted of 88 consecutive essential hypertensive patients (age 59.2 ± 1.2 years, 35 males). All subjects underwent a fundoscopy examination and were distributed into four groups according to the Keith-Wagener-Barker (KWB) classification. The four groups (KWB grades 0-3: including 26, 20, 26, and 16 patients, respectively) did not differ with regard to age, gender, or metabolic profile. There were no significant differences between groups with regard to parameters reflecting LV systolic function and diastolic dysfunction (DD) in two-dimensional echocardiography (2DE). Nevertheless, patients in the higher KWB category had higher values of LA volumes (LA maximal volume index, LA minimal volume index, preatrial contraction volume index, LA total stroke volume index, LA active stroke volume index, p < 0.001) regarding RT3DE. There is also a significant relationship between LA active stroke volume index (ASVI) and duration of hypertension (HT) (r: 0.68, p < 0.001). In the logistic regression analysis, ASVI was independent predictors of LV DD in patients with arterial hypertension (HT). Patients with arterial HT were found to have increased LA volumes and impaired diastolic functions. Assessment of the arterial HT patient by using RT3DE atrial volume analysis may facilitate early recognition of TOD, which is such a crucial determinant of cardiovascular mortality and morbidity.

Impact of Left Ventricular Diastolic Property on Left Atrial Function from Simultaneous Left Atrial and Ventricular Three-Dimensional Echocardiographic Volume Measurement. Am J Cardiol 2017; 119:1687-1693. [PMID: 28363352 DOI: 10.1016/j.amjcard.2017.02.002] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2016] [Revised: 02/06/2017] [Accepted: 02/06/2017] [Indexed: 12/28/2022]
Abstract
Simultaneous left atrial (LA) and left ventricular (LV) 3-dimensional (3D) echocardiographic volume measurements enable the quantifying of precise LA function, by virtue of their independence on any geometric assumption and capability of measurement for net LA conduit volume. We sought to elucidate the impact of conventional Doppler LV diastolic property on LA volume and function derived from this method. Our study subjects consisted of 381 patients who underwent 3D echocardiography. From LA time-volume curve, maximum and minimum volume index (VI) and VI before atrial contraction (LAVIpre-c) were determined; subsequently, active emptying volume was calculated as LAVIpre-c - minimum LAVI. From LA and LV volume measurement, conduit volume was calculated as LV stroke VI - (maximum LAVI - minimum LAVI). LA volume increased depending on the severity of diastolic dysfunction. Compared with patients with normal diastolic function, LA booster pump function, as the contribution of active emptying volume to LV filling, was higher in those with mild diastolic dysfunction. Additionally, it gradually decreased as diastolic dysfunction was advanced from mild to moderate and moderate to severe degree (23.2 ± 15.5%, 29.5 ± 15.1%, 25.1 ± 16.2%, 14.9 ± 14.1%, respectively; p <0.001). Contrarily, conduit contribution was significantly higher in patients with severe diastolic dysfunction than in those with mild diastolic dysfunction; furthermore, conduit function tended to increase, reciprocally to booster pump function, as diastolic dysfunction grade was advanced (39.1 ± 28.8%, 36.8 ± 26.2%, 42.7 ± 25.6%, 52.9 ± 26.2%, respectively; p = 0.034). In conclusion, simultaneous LA and LV volumetric analyses through 3D echocardiography clearly demonstrate the characteristic LA functional alterations following LA dilation caused by LV diastolic dysfunction.

Abstract
Background Chronic excessive alcohol intake has been reported as a possible cause of dilated cardiomyopathy. Two-dimensional speckle-tracking echocardiography (2D-STE) is a novel method for the angle-independent and objective quantification of myocardial deformation. This study sought to assess left atrial function changes among alcoholics related to the duration of heavy drinking by 2D-STE. Methods We classified 92 asymptomatic alcoholics into mild, moderate and severe groups. Thirty age-matched controls were also recruited. We measured left atrial (LA) phasic volumes (max, min and pre-atrial contraction volume) using Simpson's method in apical four-chamber view. Passive emptying (LAPEF) and active emptying (LAAEF) indices were calculated. Global longitudinal strain rate (SRs) during left ventricular (LV) ejection, early diastolic strain rate (SRe) during LV early diastole and peak negative strain rate (SRa) after the P-wave were also obtained by averaging all atrial segments. Results The alcoholics had larger LA volumes (max, min and pre-atrial contraction volume) since moderate stage (P < 0.01). LAPEF, SRs SRe, and E/A ratio showed progressive decrease according to the grades of alcoholism. The differences between the groups were significant, beginning from the moderate group (P < 0.01). During LAAEF, SRa values increased with the disease severity up to moderate alcoholics and then deteriorated significantly in severe alcoholics (P < 0.01). Conclusions These data suggest that 2D-STE may be considered a promising tool for the early detection of impairment of LA function in alcoholics.

Abstract
OBJECTIVES This study sought to observe the relationship between left atrial (LA) strain and left ventricular diastolic function and determine whether LA strain could be used to detect diastolic dysfunction (DD) and classify its degree when present. BACKGROUND The assessment of diastolic function is complex and multiparametric because most conventional parameters do not follow the progression of DD. Strain imaging is an emerging index of LA function, with recent data demonstrating that LA strain is diminished in diastolic heart failure. However, LA strain is not part of the standard assessment of diastolic function. We hypothesized that LA strain decreases with worsening DD in a stepwise fashion and could thus be useful in evaluating DD. METHODS We performed a retrospective derivation and validation cohort study to derive and test LA strain thresholds for DD grades (0 to 3) in patients with preserved left ventricular ejection fraction (N = 229). Two-dimensional speckle tracking was used to measure peak LA strain, which was applied as a single parameter to classify DD. American Society of Echocardiography guidelines were used as the reference standard. RESULTS In the derivation cohort (n = 90), peak LA strain was significantly different between DD groups, with gradual decreases seen with worsening DD. Receiver-operating characteristic analysis resulted in 3 distinct LA strain thresholds for categorization of DD grades, with good to excellent diagnostic utility (area under the curve: 0.86 to 0.91). In an independent validation group (n = 139) with a spectrum of diastolic function, 11 patients (8%) had indeterminate DD grades using standard criteria, whereas LA strain was measured in all patients and its cutoffs resulted in diagnostic accuracy up to 95%. CONCLUSIONS LA strain measurements are feasible and allow accurate categorization of DD, because unlike the traditional parameters, it changes progressively with severity of DD. LA strain may become a useful tool for diastolic assessment in future clinical practice.

Abstract
OBJECTIVE To evaluate additional role of left atrial two-dimensional speckle tracking echocardiography in patients with diabetes mellitus type 2, 218 patients with heart failure with preserved left ventricular ejection fraction divided according to the presence of diabetes mellitus (108 with and 110 without) were enrolled in the study. METHODS Traditional parameters using two-dimensional echocardiography and Doppler imaging were measured as expressions of left ventricular diastolic function as well as peak atrial longitudinal strain and peak atrial contraction strain were measured using two-dimensional speckle tracking echocardiography. RESULTS Global average peak atrial longitudinal strain and peak atrial contraction strain were significantly lower in patients with diabetes mellitus (p = 0.002 and p = 0.001, respectively) and its reduced values were significantly associated with higher prevalence of diabetes mellitus (p = 0.002 and p = 0.001, respectively), its greater severity (p = 0.002 and p = 0.016, respectively) and longer duration only for global average peak atrial longitudinal strain (p = 0.030). Multiple linear regression analysis demonstrated that the presence of diabetes mellitus appeared as independent predictor of reduced global peak atrial longitudinal strain [B = -2.173; 95% confidence interval: -3.870 to (-0.477); p = 0.012] as well of reduced global peak atrial contraction strain [B = -1.30; 95% confidence interval: -2.234 to (-0.366); p = 0.007]. CONCLUSION Two-dimensional speckle tracking echocardiography appeared as a useful additional tool for detection of left atrial dysfunction in patients with heart failure who have preserved left ventricular ejection fraction and diabetes mellitus who are especially prone to develop cardiovascular complications.

Abstract
BACKGROUND Standardized methods to evaluate atrial properties in single ventricles are lacking. OBJECTIVE To determine the feasibility of quantifying right atrial volumes and function in hypoplastic left heart using MRI. MATERIALS AND METHODS We studied 15 infants with hypoplastic left heart prior to Glenn surgery (mean age 4.2 months [standard deviation 0.3]) who underwent cardiac MRI with evaluation of atrial volumes and emptying fraction using monoplane two-chamber, monoplane four-chamber, and biplane methods, all of which were compared to the atrial short-axial oblique stack method. We compared atrial end-diastolic volume, end-systolic volume and emptying fraction among these methods. We analyzed reproducibility of the methods using Bland‒Altman plots. RESULTS Both four-chamber and biplane methods showed high correlations for atrial end-diastolic volume (r = 0.7 and r = 0.8, respectively; P < 0.01) and end-systolic volume (r = 0.8 and r = 0.9, respectively; P < 0.01) with small mean differences (-0.2 ± 2.9 standard deviation [SD] ml and -0.8 ± 1.6 ml, respectively, for atrial end-diastolic volume and -0.8 ± 1.5 ml and -0.9 ± 0.9 ml, respectively, for atrial end-systolic volume). The short-axial oblique method was the most reproducible, followed by the four-chamber method. CONCLUSION MRI assessment of atrial volume and function is feasible in hypoplastic left heart and might provide further insight into single-ventricle mechanics.

Abstract
Background After left atrial appendage (LAA) device closure, peri-device leakage into the LAA persists due to incomplete occlusion. We hypothesized that pre-procedural three-dimensional (3D) geometric analysis of the interatrial septum (IAS) and LAA orifice can predict this leakage. We investigated the predictive parameters of LAA device closure obtained from baseline cardiac computerized tomography (CT) using a novel 3D analysis system. Methods We conducted a retrospective study of 22 patients who underwent LAA device closure. We defined peri-device leakage as the presence of a Doppler signal inside the LAA after device deployment (group 2, n = 5) compared with patients without peri-device leakage (group 1, n = 17). Conventional parameters were measured by cardiac CT. Angles θ and φ were defined between the IAS plane and the line, linking the LAA orifice center and foramen ovale. Results Group 2 exhibited significantly better left atrial (LA) function than group 1 (p = 0.031). Pre-procedural θ was also larger in this group (41.9° vs. 52.3°, p = 0.019). The LAA cauliflower-type morphology was more common in group 2. Overall, the patients' LA reserve significantly decreased after the procedure (21.7 mm3 vs. 17.8 mm3, p = 0.035). However, we observed no significant interval changes in pre- and post-procedural values of θ and φ in either group (all p > 0.05). Conclusion Angles between the IAS and LAA orifice might be a novel anatomical parameter for predicting peri-device leakage after LAA device closure. In addition, 3D CT analysis of the LA and LAA orifice could be used to identify clinically favorable candidates for LAA device closure.

Abstract
Purpose To assess the impact of left ventricular (LV) diastolic dysfunction on left atrial (LA) phasic volume and function using dual-source CT (DSCT) and to find a viable alternative prognostic parameter of CT for LV diastolic dysfunction through quantitative evaluation of LA phasic volume and function in patients with LV diastolic dysfunction. Materials and Methods Seventy-seven patients were examined using DSCT and Doppler echocardiography on the same day. Reservoir, conduit, and contractile function of LA were evaluated by measuring LA volume (LAV) during different cardiac phases and all parameters were normalized to body surface area (BSA). Patients were divided into four groups (normal, impaired relaxation, pseudonormal, and restrictive LV diastolic filling) according to echocardiographic findings. The LA phasic volume and function in different stages of LV diastolic function was compared using one-way ANOVA analysis. The correlations between indexed volume of LA (LAVi) and diastolic function in different stages of LV were evaluated using Spearman correlation analysis. Results LA ejection fraction (LAEF), LA contraction, reservoir, and conduit function in patients in impaired relaxation group were not different from those in the normal group, but they were lower in patients in the pseudonormal and restrictive LV diastolic dysfunction groups (P < 0.05). For LA conduit function, there were no significant differences between the patients in the pseudonormal group and restrictive filling group (P = 0.195). There was a strong correlation between the indexed maximal left atrial volume (LAVmax, r = 0.85, P < 0.001), minimal left atrial volume (LAVmin, r = 0.91, P < 0.001), left atrial volume at the onset of P wave (LAVp, r = 0.84, P < 0.001), and different stages of LV diastolic function. The LAVi increased as the severity of LV diastolic dysfunction increased. Conclusions LA remodeling takes place in patients with LV diastolic dysfunction. At the same time, LA phasic volume and function parameters evaluated by DSCT indicated the severity of the LV diastolic dysfunction. Quantitative analysis of LA phasic volume and function parameters using DSCT could be a viable alternative prognostic parameter of LV diastolic function.

Abstract
PURPOSE OF REVIEW Evaluation of left atrial volume is important, as it is a biomarker of cardiovascular disease and outcomes and correlates with diastolic dysfunction severity. Left atrial volume measurements by different imaging modalities, including 2D and 3D echocardiography (2DE and 3DE), cardiac magnetic resonance (CMR) and computed tomography (CT), are reviewed in regard to recent advances, methodology, prognostic value and limitations. RECENT FINDINGS Left atrial volume assessments correlate well between the different imaging modalities; however, 2DE significantly underestimates left atrial measurements. Assessment of the left atrial minimum volume and left atrial phasic function derived volumetrically have reported superior predictive value for major adverse cardiovascular events and elevated left ventricular diastolic pressure compared with the left atrial maximum volume. SUMMARY The different imaging modalities used to assess left atrial volumes are not interchangeable, particularly for serial measurements. Although 2DE underestimates left atrial volumes, most normative as well as predictive data have been obtained using this modality. Standardization, with established normative data and classification criteria, needs to be established for other imaging modalities, additionally incorporating assessment of left atrial minimum and phasic volumes. Despite the limitations of the more simplistic 2DE, its measurements are well defined with significant prognostic value. The incremental prognostic value of the more complex imaging techniques needs to be further validated.

Abstract
The influence of type 2 diabetes mellitus on cardiac remodeling has been evaluated for decades; however, the majority of investigations were focused only on the left ventricle. The impact of diabetes on the left atrial (LA) function is less researched. LA enlargement has been shown as an independent predictor of cardiovascular morbidity and mortality in the general and diabetic population; however, LA dysfunction has been proven to be an independent predictor only in the general population. There are not much follow-up data about the influence of diabetes on LA function. New echocardiographic techniques, such as 2-dimensional speckle tracking imaging, provide more accurate, sensitive, and reliable information about LA function than traditional, volumetric methods. The aim of this review was to summarize the most recent reports about the influence of diabetes on LA function, as well as to discuss the possible mechanisms and potential clinical implications of the relationship between diabetes and LA remodeling.

Abstract
AIMS The aim of this multicentre study was to determine the normal range and the clinical relevance of the myocardial function of the left atrium (LA) analysed by 2D speckle-tracking echocardiography (2DSTE). METHODS AND RESULTS We analysed 329 healthy adult subjects prospectively included in 10 centres and a validation group of 377 patients with left ventricular diastolic dysfunction (LVDD). LA myocardial function was analysed by LA strain rate peak during LA contraction (LA-SRa) and LA strain peak during LA relaxation (LA-Strain). The range of values of LA myocardial function in healthy subjects was LA-SRa -2.11 ± 0.61 s(-1) and LA-Strain 45.5 ± 11.4%, and the lowest expected values of these LA analyses (calculated as -1.96 SD from the mean of healthy subjects) were LA-SRa -0.91 s(-1) and LA-Strain 23.1%. Concerning the clinical relevance of these LA myocardial analyses, LA-SRa and LA-Strain detected subtle LA dysfunction in patients with LVDD, even though LA volumetric measurements were normal. In addition, in these patients we found that the functional class (dyspnoea-NYHA classification) was inversely related to both LA-Strain and LA-SRa. CONCLUSION In the present multicentre study analysing a large cohort of healthy subjects and patients with LVDD, the normal range and the clinical relevance of the myocardial function of the LA using 2DSTE have been determined.

Abstract
Although often referred to as “the forgotten chamber”, compared with left ventricle (LV), especially in the past years, the left atrium (LA) plays a critical role in the clinical expression and prognosis of patients with heart and cerebrovascular disease, as demonstrated by several studies. Echocardiographers initially focused on early detection of atrial geometrical abnormalities through monodimensional atrial diameter quantification and then bidimensional (2D) areas and volume estimation. Now, together with conventional echocardiographic parameters, new echocardiographic techniques, such as strain Doppler, 2D speckle tracking and three-dimensional (3D) echocardiography, allow assessing early LA dysfunction and they all play a fundamental role to detect early functional remodelling before anatomical alterations occur. LA dysfunction and its important prognostic implications may be detected sooner by LA strain than by volumetric measurements.
