Medicine (Baltimore) 2024; 103:e38206. [PMID: 38788025 PMCID: PMC11124745 DOI: 10.1097/md.0000000000038206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Accepted: 04/19/2024] [Indexed: 05/26/2024] Open
Abstract
OBJECTIVE To evaluate left atrial volume and function in patients with paroxysmal atrial fibrillation (AF) combined with left atrial appendage thrombosis and patients with paroxysmal AF without left atrial appendage thrombosis by 3-dimensional speckle tracking imaging (3D-STI), and to explore the application value of this set of parameters in the evaluation of left atrial function in patients with paroxysmal AF. MATERIALS AND METHODS A total of 40 patients with paroxysmal AF admitted from December 2018 to December 2020 were selected as the observation group. All patients with paroxysmal AF in the observation group underwent transesophageal echocardiography. According to the presence of left atrial appendage thrombosis, the patients were divided into the AF without thrombosis group (24 cases) and the AF with thrombosis group (16 cases). Thirty normal people were selected as control group who were chosen as having no heart-related disease. The left atrial volume parameters (Left atrial maximum volume LAVmax, Left atrial minimum volume LAVmin, Left atrial volume before atrial contraction LAVpre-A, Left atrial stroke volume LAEV), left atrial ejection fraction (LAEF) and left atrial strain parameters (Left atrial reservoir longitudinal strain LASr, Left atrial conduit longitudinal strain LAScd, Left atrial contraction longitudinal strain LASct, Left atrial reservoir circumferential strain LASr-c, Left atrial conduit circumferential strain LAScd-c, Left atrial contraction circumferential strain LASct-c) of the 3 groups were measured by 3D-STI. RESULTS With the progression of paroxysmal AF, the left atrial volume increased, and the reservoir, conduit and contractile function were damaged. The left atrial volume continued to increase, and the reservoir, conduit and contractile function further decreased significantly in patients with AF combined with left atrial appendage thrombosis. LAEF was positively correlated with LASr and LASr_c. CONCLUSION Real-time 3-dimensional spot tracking imaging (3D-STI) can evaluate the changes in left atrial volume and function in patients with paroxysmal AF, and has a certain reference value for clinical judgment of disease progression and prognosis.

Novel Estimation of Left Ventricular Filling Pressure Using 3-D Speckle-Tracking Echocardiography: Assessment in a Decompensated Systolic Heart Failure Model. ULTRASOUND IN MEDICINE & BIOLOGY 2021; 47:1536-1547.

Abstract
E/e' allows for the non-invasive estimation of left ventricular (LV) filling pressure; however, Doppler malalignment can make the estimation unreliable, especially in dilated systolic failing hearts. The ratio of peak early diastolic filling rate to peak early diastolic global strain rate (FRe/SRe), which is a parameter derived from 3-D speckle-tracking echocardiography to estimate filling pressure, may be better applied in dilated systolic failing hearts because it can be obtained without the Doppler method. We investigated whether FRe/SRe could provide a better estimation of filling pressure than E/e' in 23 dogs with decompensated systolic heart failure induced by microembolization. FRe/SRe had better correlation coefficients with LV end-diastolic pressure (0.75-0.90) than did E/e' (0.40). The diagnostic accuracy of FRe/SRe in distinguishing elevated filling pressure was significantly higher than that of E/e'. This study indicates that FRe/SRe may provide a better estimation of LV filling pressure than E/e' in dilated systolic failing hearts.

Abstract
INTRODUCTION The present study was designed to define normal reference values of three-dimensional speckle-tracking echocardiography (3DSTE)-derived left atrial (LA) volumes, stroke volumes (SVs), and emptying fractions (EFs) with regard to the cardiac cycle. METHODS The present study involved 256 healthy adult subjects in sinus rhythm who underwent complete two-dimensional Doppler echocardiography and 3DSTE at the same time. However, due to inferior image quality, 87 subjects have been excluded. The remaining population sample comprised of 169 patients who gave informed consent to participate in the study. RESULTS While systolic maximum LA volume and early diastolic preatrial contraction LA volume did not change over age decades, late-diastolic minimum LA volume decreased and was lowest in subjects aged 40 to 49 years then increased after 50 years. Total atrial EF increased over age decades with a reduction after 50 years. Passive atrial EF showed a significant continuous increase over age decades. Active atrial EF did not change in younger ages and was the highest between ages 40 and 49 years with a significant impairment after 50 years. CONCLUSIONS This study shows the age- and gender-dependency of normal values of 3DSTE-derived LA volumes, stroke volumes, and emptying fractions with regard to the cardiac cycle in healthy adult subjects.

Abstract
Chronic functional mitral regurgitation (FMR) is a frequent finding of ischemic heart disease and dilated cardiomyopathy (DCM), associated with unfavourable prognosis. Several pathophysiologic mechanisms are involved in FMR, such as annular dilatation and dysfunction, left ventricle (LV) remodeling, dysfunction and dyssynchrony, papillary muscles displacement and dyssynchrony. The best therapeutic choice for FMR is still debated. When optimal medical treatment has already been set, a further option for cardiac resynchronization therapy (CRT) and/or surgical correction should be considered. CRT is able to contrast most of the pathophysiologic determinants of FMR by minimizing LV dyssynchrony through different mechanisms: Increasing closing forces, reducing tethering forces, reshaping annular geometry and function, correcting diastolic MR. Deformation imaging in terms of two-dimensional speckle tracking has been validated for LV dyssynchrony assessment. Radial speckle tracking and three-dimensional strain analysis appear to be the best methods to quantify intraventricular delay and to predict CRT-responders. Speckle-tracking echocardiography in patients with mitral valve regurgitation has been usually proposed for the assessment of LV and left atrial function. However it has also revealed a fundamental role of intraventricular dyssynchrony in determining FMR especially in DCM, rather than in ischemic cardiomyopathy in which MR severity seems to be more related to mitral valve deformation indexes. Furthermore speckle tracking allows the assessment of papillary muscle dyssynchrony. Therefore this technique can help to identify optimal candidates to CRT that will probably demonstrate a reduction in FMR degree and thus will experience a better outcome.

Abstract
Cardiac function analysis is the main focus of echocardiography. Left ventricular ejection fraction (LVEF) has been the clinical standard, however, LVEF is not enough to investigate myocardial function. For the last decade, speckle tracking echocardiography (STE) has been the novel clinical tool for regional and global myocardial function analysis. However, 2-dimensional imaging methods have limitations in assessing 3-dimensional (3D) cardiac motion. In contrast, 3D echocardiography also has been widely used, in particular, to measure LV volume measurements and assess valvular diseases. Joining the technology bandwagon, 3D-STE was introduced in 2008. Experimental studies and clinical investigations revealed the reliability and feasibility of 3D-STE-derived data. In addition, 3D-STE provides a novel deformation parameter, area change ratio, which have the potential for more accurate assessment of overall and regional myocardial function. In this review, we introduced the features of the methodology, validation, and clinical application of 3D-STE based on our experiences for 7 years.

Abstract
OBJECTIVE Noninvasive accurate assessment of left atrial (LA) size and function is an essential requirement in daily clinical practice. Real time three-dimensional (3D) echocardiography (RT3DE) with direct volumetric method has been found to be a highly accurate and reproducible noninvasive tool for the evaluation of LA dimensions and functional properties. Three-dimensional speckle tracking echocardiography (3DSTE) has just been introduced for volumetric assessments, which uses different, as called "block-matching" algorithm by strain analysis. This study was designed to compare two-dimensional (2D) echocardiography with 3DSTE for calculation of LA volumes and assessment of LA functional properties in healthy subjects. METHODS This study comprised of randomly selected 35 healthy subjects (40.9 ± 10.9 years, 20 men) in sinus rhythm, they all had undergone standard transthoracic 2D echocardiographic Doppler study extended with 3DSTE. RESULTS Two-dimensional echocardiography- and 3DSTE-derived minimum (Vmin ) and maximum (Vmax ) LA volumes and LA volume before atrial contraction (Vpre A ) did not differ significantly. Calculated functional LA properties were also compared. Good correlations were found between both techniques for Vmax (r = 0.93, P < 0.0001), Vmin (r = 0.62, P < 0.0001), and Vpre A (r = 0.74, P < 0.0001). CONCLUSIONS It may be stated that 3DSTE seems to be feasible in detection of cyclic changes in LA volumes and calculation of its functional properties is comparable to 2D echocardiography.

Abstract
BACKGROUND The aim of this study was to investigate the value of three-dimensional speckle-tracking echocardiography for the detection of subclinical left ventricular dysfunction in patients with aortic valvular disease (AVD). METHODS Fifty-nine patients with AVD in New York Heart Association functional class I or II as well as 48 controls were recruited. Patients with AVD were divided further into those with aortic stenosis (AS; n = 34) and those with aortic regurgitation (AR; n = 25). All patients underwent conventional echocardiography and three-dimensional speckle-tracking echocardiography. RESULTS Analysis of variance showed global longitudinal strain to be compromised in the AR group (-16.9% vs -19.3%, P = .015) and more dramatically decreased in the AS group (-14.3% vs -19.3%, P < .001) compared with healthy controls. Impairment of global circumferential strain was observed in patients with AR (-15.9% vs -18.5%, P = .009) but not in those with AS (-18.2% vs -18.5%, P = .768). Global area strain and global radial strain were decreased in patients with AS and those with AR compared with controls, but the difference between the two subgroups was not significant. CONCLUSIONS Strains measured by three-dimensional speckle-tracking echocardiography are useful indices of early-stage heart dysfunction caused by AVD. Longitudinal strain is more vulnerable to pressure overload caused by AS, whereas circumferential strain is more sensitive to volume overload due to AR.

Abstract
OBJECTIVE Three-dimensional (3D) speckle tracking echocardiography (3DSTE) is a novel imaging modality for assessing cardiac function. We aimed to analyze left atrial (LA) function using 3DSTE in patients with atrial fibrillation (AF). METHODS 3DSTE was performed in 20 patients prior to their pulmonary vein isolation for AF. Every patient underwent a complete two-dimensional echocardiographic study at the same time. 3DSTE-derived circumferential (CS), longitudinal (LS), radial (RS), 3D (3DS), and area strain (AS) values were measured in the basal (b), mid (m), and superior (s) regions of the LA. 3DSTE-defined maximal (LAmax ) and minimal LA volumes (LAmin ) and LA total emptying fraction were calculated automatically. Eleven randomly selected age- and gender-matched healthy volunteers served as controls. RESULTS Patients with AF had significantly larger LAmax and LAmin and reduced LS, RS and CS.3DS and AS were significantly lower throughout the LA in cases with AF (3DS-b, -m, -s [AF patients vs. controls]: -18 ± 8% vs. -29 ± 8%, P = 0.001; -14 ± 6% vs. -22 ± 7%, P = 0.002; -10 ± 7% vs. -20 ± 9%, P = 0.002; AS-b, -m, -s [AF patients vs. controls]: 35 ± 15% vs. 52 ± 13%, P = 0.004; 50 ± 21% vs. 72 ± 19%, P = 0.009; 31 ± 21% vs. 65 ± 27%, P < 0.0001, respectively). CONCLUSIONS 3DSTE-derived "uni-dimensional" LS, RS, CS, as well as novel strain parameters (3DS, AS) are significantly reduced in patients with AF compared to matched controls. 3DS and AS might be new strain parameters providing further insights into the alterations of LA function in patients developing AF.

Abstract
Heart failure is a major health problem in developed countries and a growing one in developing countries. Cardiac remodeling in heart failure affects myocardial mechanics, which requires comprehensive evaluation in three dimensions. The novel technique of 3D wall motion tracking applies speckle tracking technology to full volume, 3D echocardiographic datasets. Quantification of conventional and novel left ventricular (LV) parameters including volumes, ejection fraction, global and regional 3D strain, endocardial area strain, twist, and dyssynchrony, and identification of the site of latest mechanical activation are feasible on the basis of a single acquisition of a full-volume dataset. Clinical applications of 3D wall motion tracking include the assessment of global and regional LV performance in ischemic and nonischemic heart diseases, evaluation of mechanics in cardiomyopathies and congenital heart disease, potential selection of patients for cardiac resynchronization therapy and prediction of their response, and detection of subclinical cardiac dysfunction in diseases with likelihood of progression to heart failure. Technological advances with improvement in spatial and temporal resolution of this novel imaging modality are expected. Although 3D wall motion tracking is still in its infancy, this method has begun to provide new insights into LV mechanics and has already found clinical applications. Future developments in 3D assessment of right ventricular and myocardial layer-specific mechanics are awaited.

Abstract
In an era of rapidly expanding and evolving 3-dimensional echocardiographic (3DE) technology, 1 of the issues facing the 3DE quantification of chamber volumes and function is that different software vendors use different methodologies and algorithms. The aim of this study was to evaluate the comparability and reproducibility of 3DE direct volumetric and speckle-tracking methods for left ventricular (LV) and left atrial (LA) chamber quantification. A total of 120 subjects (mean age 53 ± 17 years, 65% men), including 88 unselected patients and 32 healthy volunteers, underwent 3DE acquisitions and analysis using direct volumetric and speckle-tracking methods successively. Measurements of LV and LA volumes and LV function were compared between the 2 3DE methods. Additionally, intraobserver and interobserver reproducibility was assessed in 40 randomly selected patients. Measurements of LV end-diastolic volume, end-systolic volume, and ejection fraction by 3DE direct volumetric and 3DE speckle-tracking methods were comparable, with good correlations (r = 0.98, r = 0.98, and r = 0.87, respectively), small biases, and narrow limits of agreement (-1 ± 8 ml, -1 ± 8 ml, and 0 ± 6%, respectively). For measurements of LA end-systolic volume and end-diastolic volume, similar correlations (r = 0.96 for both), small biases, and narrow limits of agreement (-2 ± 6 and -1 ± 5 ml, respectively) were found between the 2 methods. Intraobserver and interobserver reproducibility for LV and LA quantification were comparable for the 2 methods. In conclusion, 3DE direct volumetric and speckle-tracking methods give comparable and reproducible quantification of LV and LA volumes and function, making interchangeable application a viable option in daily clinical practice.
