Natalino LA, Marsam RK, Dinarti LK, Mumpuni H, Anggrahini DW. The Role of Global Longitudinal Strain in Predicting Left Ventricular Reverse Remodeling After Mitral Valve Replacement Surgery in Patients With Primary Mitral Regurgitation. Echocardiography 2024; 41:e15950. [PMID: 39440905 DOI: 10.1111/echo.15950] [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: 03/31/2024] [Revised: 07/02/2024] [Accepted: 07/07/2024] [Indexed: 10/25/2024] Open
Abstract
OBJECTIVES This study aimed to identify the utility of global longitudinal strain (GLS) as a reliable parameter that can accurately forecast left ventricle reverse remodeling (LVRR) in patients undergoing valve replacement surgery for severe chronic primary mitral regurgitation (MR), thereby aiding in assessing mortality and morbidity risk. METHODS This retrospective observational study involved severe primary MR patients who underwent valve replacement surgery between 2018 and 2023. Pre- and postsurgery echocardiography data were collected, with GLS measurements utilized to assess left ventricular function. Various echocardiography parameters, including MR severity and LV dimensions, were analyzed. Bivariate and multivariate analyses were performed to explore relationships between GLS and LVRR. RESULTS This study enrolled 103 patients (54.4% male; mean age 45.4 ± 13.6 years). Statistical analyses revealed GLS to be an independent predictor of LVRR, with a threshold of -16.25% showing 89% sensitivity and 50% specificity. Each 1% increase in GLS corresponded to a 1.14-fold (odds ratio [OR]: 1.14; 95% confidence interval [CI]: 1.01-1.31; p < 0.05) increased likelihood of LVRR. CONCLUSION These findings highlight GLS's potential as a prognostic marker for postsurgical outcomes in severe MR patients.

BMC Vet Res 2024; 20:431. [PMID: 39342325 PMCID: PMC11438168 DOI: 10.1186/s12917-024-04266-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2024] [Accepted: 09/03/2024] [Indexed: 10/01/2024] Open
Abstract
BACKGROUND We aimed to investigate the association between selected inflammatory and immune variables and survival of dogs with myxomatous mitral valve disease (MMVD). We evaluated data of 62 client-owned dogs with MMVD, grouped into preclinical, stable congestive heart failure (CHF) and unstable CHF. Univariate Cox proportional hazards regression analysis was used to quantify the association of white blood cell count, concentrations and percentages of T lymphocytes and their subtypes (T helper lymphocytes, cytotoxic T lymphocytes, double positive T lymphocytes, double negative T lymphocytes) and B lymphocytes with survival. P values < 0.1 in individual groups and P values < 0.05 in the group of all patients were considered significant. Spearman correlation coefficients between significant covariates were calculated to assess the relationships among variables and with survival. RESULTS In the preclinical group, percentage of double positive T lymphocytes was negatively associated with survival (hazard ratio (HR) = 2.328; P = 0.051). In the unstable CHF, T lymphocyte (HR = 1.613; P = 0.085), cytotoxic T lymphocyte (HR = 1.562; P = 0.048), double positive (HR = 1.751; P = 0.042), and double negative T lymphocyte (HR = 1.613; P = 0.096) concentrations were negatively associated with survival, as well as cytotoxic T lymphocyte (HR = 1.502; P = 0.007) concentration in the group of all patients. The percentage of T helper lymphocytes was positively associated with survival in the unstable CHF (HR = 0.604; P = 0.053) and in the group of all patients (HR = 0.733; P = 0.044). The concentration of cytotoxic T lymphocytes positively correlated with left atrial to aortic ratio (LA/Ao) (rho = 0.259, P = 0.037), and peak velocity of early diastolic mitral flow (rho = 0.259, P = 0.039), whereas the percentage of T helper lymphocytes negatively correlated with left atrial to aortic ratio (LA/Ao) (rho = -0.212, P = 0.090) and early to late mitral flow ratio (rho = -0.232, P = 0.072). CONCLUSIONS Cytotoxic T lymphocytes, T helper lymphocytes, double positive and double negative T lymphocytes as well as biomarkers cardiac troponin I, N-terminal pro-B-type natriuretic peptide, C-reactive protein are implicated in the progression of MMVD.

Abstract
This paper delves into the significance of imaging in the diagnosis, aetiology and therapeutic guidance of heart failure, aiming to facilitate early referral and improve patient outcomes. Imaging plays a crucial role not only in assessing left ventricular ejection fraction, but also in characterising the underlying cardiac abnormalities and reaching a specific diagnosis. By providing valuable data on cardiac structure, function and haemodynamics, imaging helps diagnose the condition, evaluate haemodynamic status and, consequently, identify the underlying pathophysiological phenotype, as well as stratifying the risk for outcomes. In this article, we provide a comprehensive exploration of these aspects.

Abstract
The increasing prevalence of valvular heart diseases, specifically mitral regurgitation (MR), underscores the need for a careful and timely approach to intervention. Severe MR, whether primary or secondary, when left untreated leads to adverse outcomes, emphasizing the critical role of a timely surgical or transcatheter intervention. While left ventricular ejection fraction (LVEF) remains the guideline-recommended measure for assessing left ventricle damage, emerging evidence raises concerns regarding its reliability in MR due to its volume-dependent nature. This review summarizes the existing literature on the role of LVEF and deformation imaging techniques, emphasizing the latter's potential in providing a more accurate evaluation of intrinsic myocardial function. Moreover, it advocates the need for an integrated approach that combines traditional with emerging measures, aiming to optimize the management of patients with MR. It attempts to highlight the need for future research to validate the clinical application of deformation imaging techniques through large-scale studies.

Abstract
AIMS Myocardial work (MW) estimation by pressure-strain loops using speckle tracking echocardiography (STE) has shown to evaluate left ventricular (LV) contraction overcoming the load-dependency limit of LV global longitudinal strain (GLS). This has proved useful in hemodynamic variation settings e.g. heart failure and valvular heart disease. However, the variation of MW and strain parameters across different stages of primary mitral regurgitation (MR) and its impact on symptoms, which was the aim of our study, has never been investigated. METHODS AND RESULTS Consecutive patients with mild, moderate and severe MR were prospectively enrolled. Exclusion criteria were: chronic atrial fibrillation, valvular heart prosthesis, previous cardiac surgery. Clinical evaluation, blood sample tests, ECG and echocardiography with STE and MW measurement were performed. Patients were then divided into groups according to MR severity. Differences among the groups and predictors of symptoms (as NYHA class≥2) were explored as study endpoints. Overall, 180 patients were enrolled (60 mild,60 moderate,60 severe MR). LV GLS and global peak atrial longitudinal strain (PALS) reduced according to MR severity. Global constructive work (GCW) and global wasted work (GWW) significantly improved, while global work efficiency (GWE) reduced, in patients with moderate and severe MR. Among echocardiographic parameters, global PALS emerged as the best predictor of NYHA class (p < 0.001;area under curve,AUC = 0.7). CONCLUSIONS MW parameters accurately describe the pathophysiology of MR, with initial attempt of LV increased contractility to compensate volume overload parallel to the disease progress, although with low efficacy, while global PALS is the most associated with the burden of MR symptoms.

Abstract
Asymptomatic primary mitral regurgitation due to myxomatous degeneration of the mitral valve leaflets may remain so for long periods, even as left ventricular function progresses to a decompensated stage. During the early compensated stage, the ventricle's initial response to the volume overload is an asymmetric increase in the diastolic short axis dimension, accomplished by a diastolic shift of the interventricular septum into the right ventricular cavity, creating a more spherical left ventricular diastolic shape, increasing diastolic filling and stroke volume. Early valve repair is recommended to reduce postoperative left ventricular dysfunction. Early serial measurements of left ventricular sphericity index [LV-Si]. during the compensated stage of mitral regurgitation might identify subtle changes in left ventricular shape and assist in determining the optimal earliest timing for surgical intervention.

Abstract
BACKGROUND Primary mitral regurgitation (MR) is a heterogeneous clinical disease requiring integration of echocardiographic parameters using guideline-driven recommendations to identify severe disease. OBJECTIVES The purpose of this preliminary study was to explore novel data-driven approaches to delineate phenotypes of MR severity that benefit from surgery. METHODS The authors used unsupervised and supervised machine learning and explainable artificial intelligence (AI) to integrate 24 echocardiographic parameters in 400 primary MR subjects from France (n = 243; development cohort) and Canada (n = 157; validation cohort) followed up during a median time of 3.2 years (IQR: 1.3-5.3 years) and 6.8 (IQR: 4.0-8.5 years), respectively. The authors compared the phenogroups' incremental prognostic value over conventional MR profiles and for the primary endpoint of all-cause mortality incorporating time-to-mitral valve repair/replacement surgery as a covariate for survival analysis (time-dependent exposure). RESULTS High-severity (HS) phenogroups from the French cohort (HS: n = 117; low-severity [LS]: n = 126) and the Canadian cohort (HS: n = 87; LS: n = 70) showed improved event-free survival in surgical HS subjects over nonsurgical subjects (P = 0.047 and P = 0.020, respectively). A similar benefit of surgery was not seen in the LS phenogroup in both cohorts (P = 0.70 and P = 0.50, respectively). Phenogrouping showed incremental prognostic value in conventionally severe or moderate-severe MR subjects (Harrell C statistic improvement; P = 0.480; and categorical net reclassification improvement; P = 0.002). Explainable AI specified how each echocardiographic parameter contributed to phenogroup distribution. CONCLUSIONS Novel data-driven phenogrouping and explainable AI aided in improved integration of echocardiographic data to identify patients with primary MR and improved event-free survival after mitral valve repair/replacement surgery.

Abstract
BACKGROUND Left ventricular (LV) circumferential strain has received less attention than longitudinal deformation, which has recently become part of routine clinical practice. Among other reasons, this is because of the lack of established normal values. Accordingly, the aim of this study was to establish normative values for LV circumferential strain and determine sex-, age-, and race-related differences in a large cohort of healthy adults. METHODS Complete two-dimensional transthoracic echocardiograms were obtained in 1,572 healthy subjects (51% men), enrolled in the World Alliance Societies of Echocardiography Normal Values Study. Subjects were divided into three age groups (<35, 35-55, and >55 years) and stratified by sex and by race. Vendor-independent semiautomated speckle-tracking software was used to determine LV regional circumferential strain and global circumferential strain (GCS) values. Limits of normal for each measurement were defined as 95% of the corresponding sex and age group falling between the 2.5th and 97.5th percentiles. Intergroup differences were analyzed using unpaired t tests. RESULTS Circumferential strain showed a gradient, with lower magnitude at the mitral valve level, increasing progressively toward the apex. Compared with men, women had statistically higher magnitudes of regional and global strain. Older age was associated with a stepwise increase in GCS despite an unaffected ejection fraction, a decrease in LV volume, and relatively stable global longitudinal strain in men, with a small gradual decrease in women. Asian subjects demonstrated significantly higher GCS magnitudes than whites of both sexes and blacks among women only. In contrast, no significant differences in GCS were found between white and black subjects of either sex. Importantly, despite statistical significance of these differences across sex, age, and race, circumferential strain values were similar in all groups, with variations of the order of magnitude of 1% to 2%. Notably, no differences in GCS were found among brands of imaging equipment. CONCLUSION This study established normal values of LV regional circumferential strain and GCS and identified sex-, age-, and race-related differences when present.

Its clinical value in detecting subtle myocardial dysfunction, by helping diagnose disease and allowing prediction of disease progression and earlier pharmacological intervention, has been demonstrated. Strain imaging has been the most studied and clinically used technique in the field of cardio-oncology. A relative percent reduction in left ventricular (LV) global longitudinal strain > 15% from baseline is considered a marker of early subclinical LV dysfunction and may have the potential to guide early initiation of cardioprotective therapy. The role of strain imaging is expanding to other fields, such as cardiac amyloidosis, other cardiomyopathies, valvular heart diseases, pulmonary hypertension, and heart failure with preserved ejection fraction. It is also used for the evaluation of the right ventricle and atria. This review aims to provide a current understanding of the roles of strain imaging in the evaluation and management of patients with cardiovascular diseases in clinical practice.
