Global left ventricular strains and left atrial volumes are not associated in healthy adults - Detailed analysis from the three-dimensional speckle-tracking echocardiographic MAGYAR-Healthy Study. IJC HEART & VASCULATURE 2024; 52:101411. [PMID: 38779327 PMCID: PMC11109869 DOI: 10.1016/j.ijcha.2024.101411] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 04/08/2024] [Accepted: 04/16/2024] [Indexed: 05/25/2024]
Abstract
Introduction During the heart cycle, left ventricular (LV) contractility is characterized by complex deformation and rotational mechanics, resulting in LV ejection. The present study seeks to expand our knowledge by examining dependence of LV strains representing LV deformation on left atrial (LA) volumes in healthy circumstances. Therefore, the aim of this study was to evaluate the associations between LA volumes and LV strains as assessed simultaneously by three-dimensional speckle-tracking echocardiography (3DSTE) in normal healthy adults. Methods The present study consisted of 302 healthy adults, but according to exclusion criteria, 137 subjects were excluded due to inferior image quality. The final population comprised 165 individuals (mean age: 33.1 ± 12.3 years, 75 males) who were voluntarily recruited for screening. Two-dimensional echocardiography extended with 3DSTE was performed in all subjects for detailed LV/LA analysis. Results Overall feasibility for simultaneous assessment of LV strains and LA volumes proved to be 55 % with excellent intra- and interobserver correlations. All global LV strains were similar, regardless of the LA volumes examined. All LA volumes and volume-based functional properties respecting the cardiac cycle were similar, regardless the global LV strains examined. Conclusions LV strains and LA volumes can be simultaneously assessed by 3DSTE. Global LV strains and LA volumes are not associated in healthy adults.

Autonomic function and specific right atrial functions - Is there a relationship? Correlations from the three-dimensional speckle-tracking echocardiographic MAGYAR-Healthy Study. JOURNAL OF CLINICAL ULTRASOUND : JCU 2024. [PMID: 38581157 DOI: 10.1002/jcu.23672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 02/29/2024] [Accepted: 03/07/2024] [Indexed: 04/08/2024]
Abstract
INTRODUCTION Similarly to the ventricles, the atria are under sympathetic/parasympathetic neural regulation. Accordingly, correlations were investigated between Ewing's standard cardiovascular reflex tests (SCRTs) and three-dimensional speckle-tracking echocardiography (3DSTE)-derived right atrial (RA) volumes and strains in healthy subjects. MATERIALS AND METHODS The study comprised 45 healthy adults, but 5 subjects were excluded due to inferior image quality for 3DSTE-derived RA assessments. The remaining 40 individuals being in sinus rhythm had a mean age of 35.1 ± 3.5 years (20 men). Two-dimensional, Doppler, 3DSTE and SCRTs were performed in all cases. RESULTS RA maximum volume and total and passive RA stroke volumes correlated with the Valsalva ratio. Active RA stroke volume and emptying fraction showed correlations with 30/15 ratio. Peak global and mean segmental RA circumferential (CS) and longitudinal strains (LS) showed correlation with the Valsalva ratio. At atrial contraction, global RA-LS and mean segmental RA-CS showed correlations with the Valsalva ratio. Moreover, mean segmental RA-CS correlated with 30/15 ratio and mean segmental RA radial strain showed correlations with systolic blood pressure in response to standing. Autonomic neuropathy score correlated with peak global RA-LS. CONCLUSIONS Autonomic function parameters have significant associations with specific RA functions in healthy adults, making the latter possible indicators of autonomic dysregulation.

Correlations between vegetative autonomic function and specific left atrial functions in healthy adults: Insights from the three-dimensional speckle-tracking echocardiographic MAGYAR-Healthy Study. JOURNAL OF CLINICAL ULTRASOUND : JCU 2024; 52:178-185. [PMID: 37997020 DOI: 10.1002/jcu.23603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 10/17/2023] [Accepted: 10/20/2023] [Indexed: 11/25/2023]
Abstract
INTRODUCTION The functioning of the left atrium (LA) is partly controlled by the neural system. It was purposed to evaluate correlations between the result of Ewing's 5 standard cardiovascular reflex tests (SCRTs) characterizing autonomic function and LA volumetric and functional features as assessed by three-dimensional speckle-tracking echocardiography (3DSTE) in healthy individuals. MATERIALS AND METHODS The current study comprised 18 healthy volunteers being in sinus rhythm (mean age: 35 ± 12 years, 10 men). Measurement of blood pressure, ECG, 5 SCRTs, two-dimensional Doppler echocardiography and 3DSTE were performed. These parameters were in normal ranges in all cases. RESULTS From LA volumetric parameters, only systolic total atrial emptying fraction (r = 0.559, p = 0.037) and early diastolic passive atrial emptying fraction (r = 0.539, p = 0.047) correlated with systolic blood pressure response to standing representing sympathetic autonomic function. From LA strains, peak mean segmental LA radial strain (RS) (r = -0.532, p = 0.050), global and mean segmental LA circumferential strain (CS) (r = 0.662, p = 0.010 and r = 0.635, p = 0.015, respectively) representing systolic LA function correlated with Valsalva ratio representing parasympathetic autonomic function. Global LA-RS (r = -0.713, p = 0.040) and LA-CS (r = 0.657, p = 0.011) and mean segmental LA-CS (r = 0.723, p = 0.003) at atrial contraction representing end-diastolic atrial contraction showed correlations with Valsalva ratio, as well. Peak global and mean segmental LA-CS (r = 0.532, p = 0.050 and r = 0.530, p = 0.050) and the same strains at atrial contraction (r = 0.704, p = 0.005 and r = 0.690, p = 0.006) representing systolic function and end-diastolic atrial contraction correlated with systolic blood pressure response to standing representing both parasympathetic and sympathetic autonomic functions. CONCLUSIONS Significant correlations between features of vegetative autonomic function represented by Ewing's 5 SCRTs and specific LA functions represented by 3DSTE-derived LA volume-based functional properties and strains could be demonstrated in healthy adults.

Similarities and Differences between Three-Dimensional Speckle-Tracking Echocardiography-Derived Left and Right Atrial Volumes and Volume-Based Functional Properties in the Same Healthy Adults-A Detailed Analysis from the MAGYAR-Healthy Study. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:2051. [PMID: 38138154 PMCID: PMC10744728 DOI: 10.3390/medicina59122051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 10/23/2023] [Accepted: 11/09/2023] [Indexed: 12/24/2023]
Abstract
Background and Objectives: It would be important to know what happens to the volume and volume-based functional properties of one atrium if the size of the other atrium is larger or smaller than the average. Therefore, the present study aimed to perform three-dimensional speckle-tracking echocardiography (3DSTE)-derived quantification of left atrial (LA) and right atrial (RA) volumes and volume-based functional properties to examine these associations in healthy adults with mean and lower or higher than mean atrial volumes. Materials and Methods: The present study consisted of 179 healthy volunteers with a mean age of 32.3 ± 12.3 years (92 males). Three-dimensional speckle-tracking echocardiography-derived LA and RA volumes and volume-based functional properties were determined in all cases. Results: When different LA or RA volume groups were evaluated, both LA and RA showed the same pattern of volume changes in all phases of atrial function with higher LA or RA volumes. In case of low and mean LA volumes, RA volumes were higher compared to their LA counterpart. In case of mean and high RA volumes, RA volumes proved to be higher as well. In case of mean LA or RA volumes, differences between LA and RA stroke volumes (SVs) could not be detected, but all atrial emptying fractions (EFs) were lower for RA than for LA. Some differences were detected in counterpart LA/RA total, passive, and active atrial SVs and EFs values in the presence of lower/higher than mean LA/RA volume. Conclusions: In case of mean LA or RA volumes, RA volumes are higher compared to their LA counterpart, LA-SVs and RA-SVs are similar, but atrial EFs are lower for RA than for LA. If lower/higher than mean LA or RA volumes are present, some differences in patterns of changes in counterpart atrial volumes-SVs and EFs-could be detected.

Abstract
Acromegaly is an uncommon systematic endocrine disease caused by the hypersecretion of human growth hormone and, consequently, of insulin-like growth factor-1 during adulthood. Acromegaly could cause a typical cardiomyopathy characterized by left ventricular hypertrophy associated with diastolic dysfunction, which later could progress to systolic dysfunction. Moreover, some valvular and vascular abnormalities are also associated with acromegaly. This present review aims to summarize available information regarding acromegaly-associated abnormalities in myocardial, valvular, and vascular structural and functional properties and their relationship to disease activity and treatment options.

The Relationship between Tricuspid Annular Longitudinal and Sphincter-like Features of Its Function in Healthy Adults: Insights from the MAGYAR-Healthy Study. Life (Basel) 2023; 13:2079. [PMID: 37895460 PMCID: PMC10608609 DOI: 10.3390/life13102079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 09/25/2023] [Accepted: 09/28/2023] [Indexed: 10/29/2023] Open
Abstract
INTRODUCTION The tricuspid valve is an atrioventricular valve located on the right side of the heart, which consists of the fibrous tricuspid annulus (TA), three valvular leaflets and a supporting apparatus, the papillary muscles and the tendinous chords. The TA is an oval-shaped three-dimensional (3D) fibrous structure with a complex spatial movement during the cardiac cycle. Three-dimensional echocardiography (3DE) could help during "en-face" assessment of TA dimensions and related functional properties featuring its "sphincter-like" function. TA plane systolic excursion (TAPSE) is a displacement of the lateral edge of the TA toward the apex in systole measured in apical long-axis using M-mode echocardiography (MME). The aim of this study was to determine potential relationships between TA size and its "sphincter-like" and "longitudinal" functions in healthy adults with no functional tricuspid regurgitation. METHODS The present study consisted of 119 healthy patients (age: 34.6 ± 11.5 years, 70 men) who underwent routine echocardiography with M-mode-derived TAPSE measurement and 3DE. Two subgroups of healthy subjects were compared with each other. A total of 29 subjects with TAPSE between 17 and 21 mm were compared with 90 cases with TAPSE ≥ 22 mm. RESULTS Subjects with TAPSE of 17-21 mm had tendentiously dilated TA dimensions compared with subjects with TAPSE ≥ 22 mm. Significant differences could be detected in the end-systolic TA area (5.85 ± 1.90 cm2 vs. 3.70 ± 1.22 cm2, p < 0.05), leading to impaired TAFAC (24.8 ± 9.0% vs. 35.1 ± 9.1%, p < 0.05) in subjects with lower TAPSE (17-21 mm) compared with subjects with TAPSE ≥ 22 mm. TAPSE did not show correlations with any TA size or "sphincter-like" functional parameters as determined using 3DE. CONCLUSIONS Three-dimensional echocardiography is capable of measuring TA dimensions and functional "sphincter-like" properties, which are associated with MME-derived TAPSE, suggesting a sensitive and harmonic TA function in healthy adults without functional tricuspid regurgitation.

Left ventricular deformation in patients with lymphedema before and after the use of medical compression stockings-detailed analysis from the three-dimensional speckle-tracking echocardiographic MAGYAR-Path Study. Quant Imaging Med Surg 2023; 13:6590-6597. [PMID: 37869293 PMCID: PMC10585567 DOI: 10.21037/qims-23-243] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 08/01/2023] [Indexed: 10/24/2023]
Abstract
Background Lymphedema (LE) is a chronic condition, which refers to tissue swelling due to excess interstitial fluid accumulation or impaired lymphatic conduit. Theoretically, lymphedema-related fluid retention could affect left ventricular (LV) mechanics, which could be detailed by recent three-dimensional speckle-tracking echocardiography. Therefore, it was purposed to examine LV strains in LE patients before and one hour after the use of medical compression stockings and to compare findings to those of matched normal subjects. Methods The study comprised 26 cases with lymphedema, however, 4 cases had to be excluded due to inferior quality of images. Their results were compared to 27 age- and gender-matched healthy controls. Results Global LV circumferential and area strains and mean segmental LV circumferential strain were increased in lymphedema patients before the use of medical compression stockings as compared to controls. One hour after the use of medical compression stockings, no global and mean segmental LV strain showed significant impairment or improvement, but tendentious reduction was seen in LV circumferential strain. With LV segmental analysis, midventricular LV radial, circumferential and area strains proved to be significantly increased, while basal LV longitudinal strain and midventricular LV three-dimensional strain were decreased as compared to controls. No changes in regional LV strains could be detected after one-hour medical compression stockings use as compared to data collected at rest. Conclusions Increased global LV circumferential strain is seen in lymphedema. With using medical compression stockings, LV deformation parameters change towards the normal range emphasizing their importance on cardiac function.

Left ventricular rotational mechanics and left ventricular volumes: is there a relationship in healthy adults?-three-dimensional speckle-tracking echocardiography-derived insights from the MAGYAR-Healthy Study. Quant Imaging Med Surg 2023; 13:6583-6589. [PMID: 37869328 PMCID: PMC10585552 DOI: 10.21037/qims-23-178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 08/01/2023] [Indexed: 10/24/2023]
Abstract
Background Left ventricular (LV) rotational mechanics play a crucial role in LV pump function by strengthening and improving its efficacy. Dependence of LV rotational parameters on left atrial volumes has already been demonstrated. The evaluation of the effect of LV rotational mechanics on LV volumes was purposed in a population of healthy subjects by three-dimensional speckle-tracking echocardiography (STE). Methods The study comprised 175 healthy subjects with a mean age of 32.8±12.2 years (79 males). All subjects underwent a complete physical examination, laboratory assessments, standard 12-lead electrocardiography and two-dimensional Doppler and three-dimensional STE, the results of these examinations were within the normal range. Results Increased basal LV rotation was associated with increased LV volume measured in end-systole and impaired LV ejection fraction. Increased apical LV rotation was associated with reduced LV volumes assessed in end-diastole and in end-systole and increased ejection fraction of the LV. Elevated basal LV rotation showed associations with increased LV mass. In case of increasing basal LV rotation, apical LV rotation showed a decreasing tendency and LV twist showed a tendency of increasing. Similarly, lower basal LV rotation and increased LV twist were seen with increasing apical LV rotation. Increasing LV end-diastolic volume was associated with increasing LV volume measured in end-systole and preserved ejection fraction of the LV. Increasing LV end-systolic volume was associated with increasing LV end-diastolic volume and reduction of LV ejection fraction. Increasing LV volumes were associated with increasing LV mass. While increased LV volumes were associated with reduced apical LV rotation and twist, basal LV rotation did not show significant changes. Conclusions LV rotational mechanics are strongly associated with LV volumes in healthy adults suggesting its volume-dependence.

Tricuspid annular and right atrial volume changes are associated in healthy adults-insights from the three-dimensional speckle-tracking echocardiographic MAGYAR-Healthy Study. Front Cardiovasc Med 2023; 10:1140599. [PMID: 37731528 PMCID: PMC10507328 DOI: 10.3389/fcvm.2023.1140599] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 08/07/2023] [Indexed: 09/22/2023] Open
Abstract
Introduction The tricuspid valve and its annulus (TA) and the right atrium (RA) play a significant role in regulating blood flow in the right heart. However, their effect on each other is not fully understood even in normal circumstances. Three-dimensional (3D) speckle-tracking echocardiography (3DSTE) is able to simultaneously assess TA and RA at the same time in a non-invasive way. The present study aimed to examine associations between tricuspid annular (TA) dimensions and right atrial (RA) volumes in healthy adults by 3DSTE. Methods The present study comprised 144 healthy subjects (mean age: 34.4 ± 12.6 years, 72 males), who participated in this study on a voluntary basis for screening between 2011 and 2015. In all subjects, electrocardiography, two-dimensional Doppler echocardiography and 3DSTE have been performed. Results With increasing end-systolic maximum RA volume, all end-systolic and end-diastolic TA dimensions showed simultaneous increase, but in various degrees resulting in (non-significant) reduction of TA functional properties. Similarly, with increasing diastolic pre-atrial contraction and minimum RA volumes, TA dimensions increased simultaneously (except end-diastolic TA diameter), but in various degrees resulting in reduced TA fractional shortening and fractional area change. With increasing RA dimensions, end-systolic and end-diastolic TA dimensions showed simultaneous increase, but in different, sometimes not significant degrees. While RA stroke volumes showed increasing pattern with TA dilation, RA emptying fractions have not changed substantially. Conclusions 3DSTE is suitable for non-invasive assessment of TA dimensions and RA volumes at the same time using the same 3D echocardiographic dataset. Significant associations between TA size and RA volumes exist in healthy circumstances. Strong associations in case of dilation of TA in the presence of higher RA volumes could partly explain functional tricuspid regurgitation later developing in subjects in sinus rhythm.

Complexity of left ventricular strains in response to elevated volumes in healthy adults - Detailed analysis from the three-dimensional speckle-tracking echocardiographic MAGYAR-Healthy Study. IJC HEART & VASCULATURE 2023; 47:101236. [PMID: 37484064 PMCID: PMC10359859 DOI: 10.1016/j.ijcha.2023.101236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 06/14/2023] [Accepted: 06/26/2023] [Indexed: 07/25/2023]
Abstract
Introduction Cardiac haemodynamics is described by the Frank-Starling law, which states that the strength of the left ventricular (LV) systolic contraction is related to the LV diastolic filling, with other words LV stroke volume increases as LV volume increases due to the stretching of the myocyte. The purpose of the present study was to examine how the increasing LV volumes affect LV contractility represented by three-dimensional (3D) speckle-tracking echocardiography (3DSTE) -derived LV strains in healthy adults. Methods This is post-hoc analysis of the MAGYAR-Healthy Study employing a novel method for technical analysis of echocardiographic datasets. The present study consisted of 301 healthy adults. Due to inferior image quality, 127 subjects have been excluded, therefore the remaining population included 174 subjects (mean age: 32.9 ± 12.1 years, 80 males). All cases have undergone complete two-dimensional Doppler echocardiography extended with 3DSTE. Results LV global longitudinal (gLS) and area (gAS) strains were lowest in case of the highest LV end-diastolic volume (EDV). LV global radial (gRS) and 3D (g3DS) strains tendentiously increased with increasing LV-EDV. When segmental analysis was performed, increased LV-EDV was associated with increase of basal LV-RS and LV-3DS. Increased LV strains were associated with increased LV ejection fraction (EF) due to higher LV-EDV for LV-gRS (and LV-g3DS), lower LV-ESV for LV-gCS and lower LV-EDV and LV-ESV for LV-gLS (and LV-gAS). With increasing LV-gRS, LV-gCS and LV-g3DS, all LV strains increased except LV-gLS. With increasing LV-gLS, LV-gRS did not show any increase, LV-gCS and LV-g3DS were the highest when LV-gLS was the highest, while LV-gAS increased simultaneously. With increasing LV-gAS, all LV strains increased. Conclusions There is a complex contractility pattern of LV segments/regions in response to elevated LV volumes in healthy circumstances.

Three-Dimensional Speckle-Tracking Echocardiography-Derived Tricuspid Annular Dimensions and Right Atrial Strains in Healthy Adults-Is There a Relationship? (Insights from the MAGYAR-Healthy Study). J Clin Med 2023; 12:4240.

Abstract
INTRODUCTION The tricuspid valve and its annulus (TA) are thought to be integrally related to right atrial (RA) size and function. The present study aimed to assess associations between TA dimensions and RA strains, and quantitative features of its contractility were determined by 3DSTE in healthy adults. METHODS The study comprised 145 healthy volunteers with a mean age of 34.4 ± 12.5 years (73 males). Electrocardiographic, two-dimensional Doppler echocardiographic and 3DSTE parameters were in normal reference ranges in all subjects. RESULTS Enlarged TA areas, regardless of which phase of the cardiac cycle were measured, were not associated with the deterioration of peak RA strains in longitudinal (LS) and circumferential (CS) directions. Increased end-diastolic TA area was associated with reduced RA strain in the radial direction (RS). Dilation of end-diastolic and end-systolic TA areas was related to increased RA volumes. End-diastolic TA area was the smallest in case of increased peak global RA-RS, and other associations between increasing TA areas and peak global strains could not be detected. Peak global RA-CS and RA-LS were not related to TA areas. Increasing peak global RA-RS was not associated with peak global RA-LS and RA-CS, while increasing peak global RA-LS and RA-CS were not associated with peak global RA-RS. Increasing peak global RS did not show associations with RA volumes, Vmin was the smallest in the case of highest peak global RA-CS and RA-LS. Vmax increased with increasing peak global RA-LS. CONCLUSIONS 3DSTE is suitable for simultaneous non-invasive determination of TA dimensions and RA volumes and strains using the same acquired 3D dataset, allowing physiologic studies. RA volumes are associated with end-diastolic and end-systolic TA areas. RA strains in radial direction (RS) show associations with end-diastolic TA area.

Simultaneously Assessed Three-Dimensional Speckle-Tracking Echocardiography-Derived Left Ventricular and Left Atrial Volumes Are Associated in Healthy Adults-Findings from the MAGYAR-Healthy Study. J Clin Med 2023; 12:4153. [PMID: 37373846 DOI: 10.3390/jcm12124153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 05/24/2023] [Accepted: 06/02/2023] [Indexed: 06/29/2023] Open
Abstract
INTRODUCTION The left atrium (LA) has a significant role in regulating blood flow from veins to the left ventricle (LV). LV performance is affected by several factors including preload, which is partly, but highly, dependent on LA volumes. The aim of the present study is to perform simultaneous assessment of LA and LV volume changes during the cardiac cycle in healthy circumstances. Therefore, LA and LV volumes and volume-based functional properties were determined in healthy adults, and the associations of these parameters were examined. METHODS The present study consists of 164 healthy adults (age: 33.0 ± 12.3 years, 82 males) being in sinus rhythm. All subjects have undergone complete two-dimensional Doppler echocardiography with three-dimensional speckle-tracking echocardiography (3DSTE). RESULTS Increased end-systolic maximum LA volume was associated with higher LV volumes and reduced LV ejection fraction. Very high early pre-atrial contraction and late diastolic LA volumes were associated with increased LV volumes, reduced LV ejection fraction and increased LV mass. Increased LA volumes were associated with increased LV mass. Higher LV volumes were associated with tendentiously higher LA volumes. Higher LV end-diastolic volume was associated with tendentiously higher all LA stroke volumes (SVs) and total and active LA emptying fractions (EFs). Higher LV end-systolic volume was associated with tendentiously higher all LA SVs but preserved all LA EFs. CONCLUSIONS 3DSTE is capable of simultaneous assessment of LA and LV volumes and volume-based functional properties for (patho)physiologic studies. Moreover, 3DSTE-derived LV and LA volumes and functional properties show strong associations.

Results from the three-dimensional speckle-tracking echocardiographic MAGYAR-Sport and MAGYAR-Path Studies]. Orv Hetil 2023; 164:308-316. [PMID: 36842148 DOI: 10.1556/650.2023.32720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Accepted: 12/27/2022] [Indexed: 02/27/2023]
Abstract
INTRODUCTION Acromegaly is a chronic endocrine disorder, which produces a significant amount of human growth hormone and consequently insulin-like growth factor in adulthood due to a tumor in the pituitary gland. If left untreated, it can have a significant effect on the cardiovascular system. It is also known that elite sport activity is also associated with physiologic cardiac transformation, the so-called athletes' heart, in which volumetric and functional adaptation of the heart cavities can be observed. OBJECTIVE In accordance with the above facts, the question may rightly arise as to what differences can be observed in left ventricular morphology and function in acromegaly, and what similarities and dissimilarities do the obtained results show compared to the values of healthy non-athlete adults compared to the values of the left ventricle of young elite athletes. METHOD The present study comprised 21 elite athletes playing high dynamic sports (mean age: 31.2 ± 6.4 years, 13 males) and 18 acromegaly patients (mean age: 47.9 ± 8.9 years, 9 males). Their results were compared to those of 22 negative controls (mean age: 47.7 ± 10.6 years, 13 males). RESULTS Left ventricle is dilated, but its function is preserved in both elite athletes and patients with acromegaly. While increased longitudinal and circumferential left ventricular strains could be seen in elite athletes primarily due to the more pronounced contractility of left ventricular apical segments, increased radial left ventricular strain was detected in acromegaly due to increased function of the left ventricular basal region. Left ventricular rotational mechanics show different patterns as well: while basal left ventricular rotation is decreased in elite athletes, apical left ventricular rotation showed a reduction leading to the significant deterioration of left ventricular twist in acromegaly. CONCLUSION Both elite athletes playing high dynamic sports and acromegaly patients have dilated left ventricle, more pronounced regional left ventricular contractility and left ventricular rotational abnormalities with differences in nature and extent of these alterations as compared to those of non-sporting healthy subjects.

Prognostic role of three-dimensional speckle-tracking echocardiography-derived left ventricular global longitudinal strain in cardiac amyloidosis: Insights from the MAGYAR-Path Study. JOURNAL OF CLINICAL ULTRASOUND : JCU 2023. [PMID: 36840337 DOI: 10.1002/jcu.23445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 01/31/2023] [Accepted: 02/09/2023] [Indexed: 06/18/2023]
Abstract
INTRODUCTION Systemic amyloidosis is an uncommon disorder in which amyloid fibrils deposit extracellularly. Three-dimensional speckle-tracking echocardiography (3DSTE) is a novel method able to assess left ventricular (LV) global longitudinal strain (GLS). Our aim was to evaluate the prognostic impact of 3DSTE-derived LV-GLS in patients with cardiac amyloidosis (CA). MATERIALS AND METHODS A total of 35 patients suffering from light-chain (AL) CA or transthyretin (TTR) CA were selected, but 7 patients had to be excluded due to insufficient image quality or were lost for follow-up. With AL-CA 23 cases, while for TTR-CA 5 patients were diagnosed. Complete two-dimensional Doppler and 3DSTE were performed in all subjects. RESULTS The median follow-up was 201 days (ranging from 36 to 632 days) during which cardiovascular event was detected in 17 CA patients, including 8 cardiac deaths. Six patients were diagnosed with acute heart failure, two patients needed invasive interventions (percutaneous coronary intervention with stent-implantation, implantable cardioverter defibrillator implantation) and in one patient new higher grade atrioventricular block was registered. Using ROC analysis, 3DSTE-derived LV-GLS ≥11.8% (absolute value) was found to be a significant predictor for cardiovascular event-free survival (sensitivity 65%, specificity 64%, area under the curve 0.71, p = .05). Lower LV ejection fraction was confirmed in patients with LV-GLS <11.8% as compared to cases with LV-GLS ≥11.8%. In case of a cardiovascular event, LV-GLS was lower as compared to that of subjects with no events. Multivariable regression analysis confirmed that LV-GLS and LV end-diastolic diameter were independent predictors of cardiovascular survival. CONCLUSION 3DSTE-derived LV-GLS is an independent predictor for future cardiovascular events in CA patients.

Abstract
INTRODUCTION There is an increasing ratio of surviving patients with congenital heart disease including tetralogy of Fallot. OBJECTIVE The aim of the present study was a comparative assessment of echocardiographic and cardiac magnetic resonance imaging-derived findings in patients with tetralogy of Fallot following early total reconstruction versus early palliation/late correction. METHODS The study comprised 17 patients with tetralogy of Fallot (mean age: 28.6 ± 10.4 years; 10 males). Early total reconstruction was performed in 10 cases (mean age: 25.0 ± 8.0 years; 8 males), while early palliation/late construction was done in 7 subjects (mean age: 33.7 ± 11.8 years; 2 males). Complete two-dimensional Doppler echocardiography and cardiac resonance imaging were performed in all patients. RESULTS During long-term follow-up, lower left ventricular end-systolic (40.50 ± 10.55 ml/m2 vs. 58.14 ± 19.07 ml/m2, p = 0.013) and end-diastolic volume indices (86.60 ± 12.62 ml/m2 vs. 116.70 ± 23.70 ml/m2, p = 0.002) and stroke volume index (46.00 ± 6.77 ml/m2 vs. 58.43 ± 7.11 ml/m2, p = 0.001) could be detected, which were associated with higher echocardiographic left ventricular ejection fraction (69.75 ± 6.80% vs. 61.67 ± 8.80%, p = 0.038) in patients with tetralogy of Fallot following early total reconstruction as compared to that of subjects late after early palliation/late correction. In regard with the right heart, larger right ventricular muscle mass (72.33 ± 21.03 g/m2 vs. 51.33 ± 22.33 g/m2, p = 0.044) could be seen in patients with tetralogy of Fallot following early total reconstruction. CONCLUSION Beneficial left ventricular morphological and functional parameters, but more pronounced right ventricular hypertrophy could be detected in patients with tetralogy of Fallot following early total reconstruction as compared to that of subjects late after early palliation/late correction.

Dependence of Left Ventricular Rotational Mechanics on Left Atrial Volumes in Non-Smoker Healthy Adults: Analysis Based on the Three-Dimensional Speckle-Tracking Echocardiographic MAGYAR-Healthy Study. J Clin Med 2023; 12:jcm12031235. [PMID: 36769883 PMCID: PMC9917922 DOI: 10.3390/jcm12031235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 01/25/2023] [Accepted: 01/26/2023] [Indexed: 02/09/2023] Open
Abstract
Introduction: As has been established, the left ventricle (LV) and the left atrium (LA) form an organic unit of the left heart; however, little is known about the dependence of LV rotational parameters on LA volumes, even in healthy circumstances. Therefore, the present study aimed to assess the associations between basal and apical LV rotations and LA volumes and volume-based functional properties throughout the cardiac cycle in healthy adults by three-dimensional speckle-tracking echocardiography. Methods: The present study comprised 167 healthy adults (age: 33.4 ± 12.6 years, 77 males) with normally directed LV rotational mechanics. All subjects underwent complete two-dimensional Doppler echocardiography with three-dimensional speckle-tracking echocardiography (3DSTE)-derived data acquisition. The 3DSTE-derived LA volumes and LV rotational parameters were determined at a later date. Results: An increasing end-systolic maximum LA volume (Vmax) was associated with increasing pre-atrial-contraction early (VpreA) and minimum end-diastolic (Vmin) LA volumes, and all stroke volumes were increased as well. Systolic basal left ventricular rotation (LVrot) was highest in the case of the highest systolic Vmax and early-diastolic VpreA. Apical LVrot did not show obvious associations with any increasing LA volumes. The highest systolic basal LVrot was associated with significantly increased diastolic VpreA and Vmin. Reduced diastolic LA volumes (VpreA, Vmin) were seen in the case of increased apical LVrot. An increasing basal LVrot was associated with the tendentious lowering of the apical LVrot and the significant elevation of LV twist. Similarly, an increasing apical LVrot was associated with the tendentious lowering of basal LVrot and the significant elevation of LV twist. Conclusions: Strong associations and adaptations between 3DSTE-derived LA volumes throughout the cardiac cycle and LV rotational mechanics were evidenced, even in healthy circumstances.

Right atrial volumes and strains in healthy adults: is the Frank-Starling mechanism working?-detailed analysis from the three-dimensional speckle-tracking echocardiographic MAGYAR-Healthy Study. Quant Imaging Med Surg 2023; 13:825-834. [PMID: 36819234 PMCID: PMC9929410 DOI: 10.21037/qims-22-307] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Accepted: 11/08/2022] [Indexed: 12/13/2022]
Abstract
Background With larger blood volume flowing into a cardiac chamber, by stretching muscle fibers, increased contraction force could be detected. This phenomenon is called Frank-Starling mechanism, allowing the output of a cardiac chamber to be synchronized without external regulation. The purpose of the present study was to investigate the Frank-Starling mechanism in the right atrium (RA) represented by its volumes, volume-based functional properties and strains respecting the cardiac cycle in healthy adults by three-dimensional (3D) speckle-tracking echocardiography (3DSTE). Methods The present single center retrospective cohort study comprised 179 healthy adult volunteers (mean age: 33.2±12.0 years, 92 males), in whom complete two-dimensional Doppler echocardiography with 3DSTE was performed. Subjects were divided into 3 groups according to the mean value of maximum RA volume (Vmax) ± standard deviation: Vmax <30 mL, 30 mL ≤ Vmax <60 mL and Vmax ≥60 mL. Results All RA volumes respecting the cardiac cycle of all subjects and calculated separately for females and males and their indexed equivalents increased with Vmax. RA stroke volumes increased with Vmax regardless of the phase it was measured in. While total atrial emptying fraction representing the reservoir phase remained unchanged with the increase of Vmax, a significant increase in passive atrial emptying fraction representing the conduit phase could be detected, in case of Vmax >60 mL (28.9%±15.1% vs. 32.5%±12.6%, P<0.05). Active atrial emptying fraction representing the booster pump function did not change with the increase of Vmax. Most global and mean segmental peak RA strains did not show significant changes with increasing RA volumes except for the RA area strain, it was the largest when Vmax was larger than 60 mL (64.7%±44.9% vs. 83.3%±49.4%, P<0.05). RA circumferential, longitudinal and area strains at atrial contraction decreased with increasing Vmax, RA radial and 3D strains did not change significantly with increasing Vmax. Conclusions Increasing RA volumes do not cause significant increase in RA contractility represented by strains, but reduction in strains in longitudinal and circumferential directions could be detected in end-diastolic booster pump function. In contrast to the left atrium, obvious signs of Frank-Starling mechanism could not be detected in case of the RA.

Quant Imaging Med Surg 2023; 13:320-328. [PMID: 36620165 PMCID: PMC9816723 DOI: 10.21037/qims-22-417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Accepted: 10/26/2022] [Indexed: 11/23/2022]
Abstract
Background Earlier results suggest the role of speckle-tracking echocardiography (STE)-derived left ventricular (LV) strains in screening and could help better understanding of adaptation to exercise. The present retrospective cohort study aimed to investigate three-dimensional STE-derived LV strains representing its deformation in athletes playing sports with high dynamics with different grades of static components of their training. Methods The study consisted of 67 athletes (mean age: 23.6±6.4 years, 39 males). This group of athletes was further divided into the following groups: Group C.I. (high dynamic/low static) (n=12), Group C.II. (high dynamic/moderate static) (n=22) and Group C.III. (high dynamic/high static) (n=33). The control group comprised 83 age- and gender-matched non-athletic healthy volunteers (mean age: 23.6±3.2 years, 50 males). Results Global LV longitudinal strain (LS) representing LV lengthening or shortening (-18.5%±3.0% vs. -16.3%±2.3%, P<0.05), LV circumferential strain (CS) representing LV widening or narrowing (-29.9%±5.2% vs. -28.1%±4.8%, P<0.05) and LV area strain (AS; combination of LS and CS; -43.7%±5.4% vs. -40.9%±4.8%, P<0.05) were increased in elite athletes as compared to those of non-athlete controls. All apical LV strains proved to be increased in all athletes with enhanced basal radial strain (RS, representing LV thickening and thinning) and LS and midventricular LS, AS and 3D strain (3DS, combination of RS, LS and CS). Conclusions Increased LV-LS, LV-CS and LV-AS represents enhanced LV deformation in longitudinal and circumferential directions in athletes playing sports with high dynamics. This enhancement is not related to the grade of the static component of training. Some regional differences in LV strains could be detected.

Abstract
Background Three-dimensional speckle-tracking echocardiography (3DSTE) is a relatively new non-invasive imaging modality with ability for simultaneous chamber quantifications and determination of valvular dimensions. The aim of the present retrospective cohort study was to determine normal reference values of 3DSTE-derived tricuspid annular (TA) dimensions and functional properties and to evaluate their age- and gender dependency. Methods The present study comprised 156 healthy adult subjects, from which 28 cases were excluded due to inferior image quality, therefore the remaining group consisted of 128 cases with the mean age of 35.4±12.5 years (72 males). The subject population was further divided into the following categories: 18-29 years (n=57; mean age: 25.2±2.8 years, 51 males), 30-39 years (n=29; mean age: 34.1±2.5 years, 31 males), 40-49 years (n=17; mean age: 44.1±3.2 years, 11 males) and ≥50 years of age (n=25, mean age: 59.2±6.4 years, 14 males). Results End-diastolic TA diameter (2.2±0.3 vs. 2.5±0.3 cm, P<0.05), area (7.1±1.3 vs. 8.1±1.7 cm2, P<0.05) and perimeter (10.3±0.9 vs. 11.0±1.2 cm, P<0.05) were lower in females than in males in the 18-29 year-old group and TA area (6.1±0.8 vs. 8.0±1.2 cm2, P<0.05) and TA perimeter (9.7±0.8 vs. 11.0±0.9 cm, P<0.05) were lower in females than in males in the 40-49 year-old group. End-systolic TA diameter were lower in females than in males in the 18-29 year-old group (1.8±0.2 vs. 1.9±0.3 cm, P<0.05) and TA area (4.7±0.3 vs. 6.3±1.2 cm2, P<0.05) and TA perimeter (8.6±0.4 vs. 9.5±0.9 cm, P<0.05) were lower in females than in males in the 40-49 year-old group. TA fractional area change was found to be reduced in the 40-49 year-old group as compared to the 30-39 year-old group (21.7%±8.7% vs. 29.2%±10.0%, P<0.05). Conclusions 3DSTE is a novel method for non-invasive assessment of TA dimensions and functional properties. Results highlight the importance of age- and gender-specific reference values in case of TA diameter, area and perimeter and calculated functional features respecting the cardiac cycle.

Screening for Myocardial Injury after Mild SARS-CoV-2 Infection with Advanced Transthoracic Echocardiography Modalities. Diagnostics (Basel) 2022; 12:diagnostics12081941. [PMID: 36010290 PMCID: PMC9406902 DOI: 10.3390/diagnostics12081941] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 08/01/2022] [Accepted: 08/06/2022] [Indexed: 01/08/2023] Open
Abstract
Although the clinical manifestations of SARS-CoV-2 viral infection affect mainly the respiratory system, cardiac complications are common and are associated with increased morbidity and mortality. While echocardiographic alterations indicating myocardial involvement are widely reported in patients hospitalized for acute COVID-19 infection, much fewer data available in non-hospitalized, mildly symptomatic COVID-19 patients. In our work, we aimed to investigate subclinical cardiac alterations characterized by parameters provided by advanced echocardiographic techniques following mild SARS-CoV-2 viral infection. A total of 86 patients (30 males, age: 39.5 ± 13.0 yrs) were assessed 59 ± 33 days after mild SARS-CoV-2 viral infection (requiring no hospital or <5 days in-hospital treatment) by advanced echocardiographic examination including 2-dimensional (2D) speckle tracking echocardiography and non-invasive myocardial work analysis, and were compared to an age-and sex-matched control group. Altogether, variables from eleven echocardiographic categories representing morphological or functional echocardiographic parameters showed statistical difference between the post-COVID patient group and the control group. The magnitude of change was subtle or mild in the case of these parameters, ranging from 1−11.7% of relative change. Among the parameters, global longitudinal strain [−20.3 (−21.1−−19.0) vs. −19.1 (−20.4−−17.6) %; p = 0.0007], global myocardial work index [1975 (1789−2105) vs. 1829 (1656−2057) Hgmm%; p = 0.007] and right ventricular free wall strain values (−26.6 ± 3.80 vs. −23.8 ± 4.0%; p = 0.0003) showed the most significant differences between the two groups. Subclinical cardiac alterations are present following even mild SARS-CoV-2 viral infection. These more subtle alterations are difficult to detect by routine echocardiography. Extended protocols, involving speckle-tracking echocardiography, non-invasive measurement of cardiac hemodynamics, and possibly myocardial work are necessary for detection and adequate follow-up.

Abstract
Introduction Hemophilia is an inherited disorder due to deficiencies in factor VIII (type A) and factor IX (type B). Abnormalities in myocardial mechanics could be theorized due to hemophilia-associated hypocoagubility and related quantitative and qualitative changes of the blood. The present study aimed a detailed assessment of left atrial (LA) volumetric and functional properties in patients with hemophilia using three-dimensional speckle-tracking echocardiography (3DSTE). Materials and Methods The study consisted of 12 subjects with hemophilia type A and 2 cases with hemophilia type B (mean age: 40.8 ± 19.1 years, all males). Results of hemophilia patients were compared to that of 23 age-, gender- and risk factor-matched controls (42.4 ± 9.0 years, all males). Routine two-dimensional Doppler echocardiography and 3DSTE were performed in all subjects. Results LA volumes respecting cardiac cycle did not differ between controls and hemophilia patients. From LA volume-based functional properties, LA stroke volumes were similar between the groups examined in all phases of LA function. While total atrial emptying fraction featuring LA reservoir function was reduced in patients with hemophilia compared to that of controls, passive and active atrial emptying fraction characterizing LA conduit and booster pump functions were similar between the groups. From LA strains, peak mean segmental circumferential and longitudinal LA strains were impaired in patients with hemophilia, other peak LA strains were similar between the groups. LA strains at atrial contraction did not differ between groups of hemophilia patients and controls. Conclusions Hemophilia is not associated with LA volumetric changes, but mild LA functional abnormalities are present.

Abstract
Introduction Amyloidosis is a rare condition due to extracellular deposition of excessive amount of protein in parenchymal tissues including the heart. The present study aimed to test whether cardiac amyloidosis (CA) is associated with morphological and functional abnormalities of the tricuspid annulus (TA). For this aim, the results of patients having CA were compared to age- and gender-matched healthy controls by three-dimensional speckle-tracking echocardiography (3DSTE). Moreover, differences in TA parameters between light-chain CA (AL-CA) and transthyretin CA (TTR-CA) were studies as well. Materials and Methods The study comprised 27 CA patients (mean age: 62.7 ± 9.1 years, 21 males), their results were compared to those of 20 age- and gender-matched healthy volunteers (59.3 ± 3.8 years, 13 males). Complete two-dimensional Doppler echocardiography and 3DSTE were performed in all CA patients and controls. Results Dilated end-diastolic and end-systolic TA diameter, area and perimeter could be detected in all CA patients and in the AL-CA and TTR-CA subgroups, as well. Although only a few TTR-CA patients were involved, morphologic TA parameters proved to be tendentiously higher as compared to those of AL-CA patients. Functional parameters of TA were found to be reduced in CA patients, which were more deteriorated in AL-CA patients. Conclusions Dilated TA is associated with its functional deterioration in CA.

Abstract
Introduction Prominent trabecular left ventricular (LV) meshwork and deep intertrabecular LV recesses are featuring LV non-compaction (LVNC). The aim of this study was to evaluate tricuspid annular (TA) morphological and functional abnormalities by three-dimensional speckle-tracking echocardiography (3DSTE) in patients with LVNC without right ventricular (RV) involvement. Materials and Methods This study consisted of 21 patients with isolated LVNC, from which 6 cases were excluded due to inferior image quality. The remaining patient group consisted of 15 subjects with a mean age of 52.1 ± 11.4 years (9 males). LVNC was defined according to the Jenni's criteria. Their results were compared to 21 age- and gender-matched healthy controls (mean age: 52.4 ± 3.9 years, 14 males). Complete routine 2-dimensional Doppler echocardiographic examination was performed in all the patients with isolated LVNC and healthy controls. End-systolic and end-diastolic TA dimensions were assessed on selected planes derived from full-volume 3D echocardiographic datasets during 3DSTE. Results Patients with isolated LVNC showed significantly dilated end-systolic and end-diastolic TA diameter and area, which were accompanied with preserved TA functional properties and associated with right atrial (RA) volumes. TA plane systolic excursion (TAPSE) showed mild correlations with TA fractional area change (TAFAC) and TA fractional shortening (TAFS). No correlations could be demonstrated between TAPSE and TA morphological features. Extent of LVNC did not correlate with any echocardiographic parameters. Conclusion TA is dilated with preserved sphincter-like function in patients with isolated LVNC. Longitudinal (TAPSE) and sphincter-like (TAFAC and TAFS) TA movements correlate with each other. TA dilation is associated with an increased RA volumes respecting cardiac cycle.

Abstract
Összefoglaló. A bal kamra funkciójának megítélésére számos
echokardiográfiás paraméter alkalmas. Bár a bal kamrai ejekciós frakció és a
globális longitudinális strain széleskörűen alkalmazott paraméterek, használatuk
során limitáló tényezők változatlanul fennállnak. A globális myocardialis munka
noninvazív meghatározása ma már elérhető klinikai lehetőség, mely kombinálja a
speckle-tracking echokardiográfiás strainanalízist a brachialis artériában
mandzsettával systoléban mért vérnyomásértékkel. Az így számítható paraméterek
töltéstől független lehetőséget nyújtanak a bal kamra funkciójának jellemzésére.
A jelen összefoglaló mű célja ennek az új módszernek a rövid bemutatása a korai
eredmények ismertetése mellett, irodalmi adatok alapján. Orv Hetil. 2022;
163(13): 495–499.
Summary. Several echocardiographic parameters are suitable for the
evaluation of left ventricular function. Although left ventricular ejection
fraction and global longitudinal strain are widely used parameters, limitations
are still persisting. Non-invasive estimation of global myocardial work has
become a new clinical opportunity, which combines speckle-tracking
echocardiography-derived strain analysis with systolic blood pressure measured
by brachial cuff. Calculated parameters make a load-independent choice for
featuring left ventricular function. The present review aimed a short
demonstration of this methodology together with early results based on
literature. Orv Hetil. 2022; 163(13): 495–499.

Abstract
BACKGROUND Hemophilia is an X-linked inherited disorder primarily affecting males, its major types are type A (deficiency in factor VIII) and B (deficiency in factor IX), and is considered to be the most common severe congenital coagulation factor deficiency. The present study was designed to test whether any differences in left ventricular (LV) rotational mechanics could be demonstrated between male patients with hemophilia and healthy controls using three-dimensional speckle-tracking echocardiography (3DSTE)-derived virtual LV models. METHODS The present study consisted of 17 patients with hemophilia, however, 3 patients were excluded due to insufficient image quality. In the remaining patient population, 12 patients had hemophilia A and 2 patients had hemophilia B (mean age: 42.2±18.9 years, all males). The control group comprised 16 age-matched healthy subjects (46.0±5.9 years, all males). RESULTS None of the routine two-dimensional echocardiographic data differ between patients with hemophilia and controls. None of the patients and controls showed ≥ grade 1 valvular regurgitations and had valvular stenoses. In one subject, the near absence of LV twist called as LV "rigid body rotation" could be detected, data of which were managed separately. While 3DSTE-derived apical LV rotation was 3.65 degrees, basal LV rotation proved to be 3.57 degrees leading to 0.08-degree LV apico-basal gradient suggesting counterclockwise LV "rigid body rotation". In the remaining patients, both LV apical rotation (7.25±6.20 vs. 10.39±4.16 degrees, P<0.02) and LV twist (10.24±5.60 vs. 14.38±3.93 degrees, P<0.003) showed significant impairment in patients with hemophilia. CONCLUSIONS LV rotational abnormalities are present in hemophilia with reduced LV apical rotation and twist.

Abstract
Reduced secretion of one or more of the hormones normally produced by the pituitary gland is called hypopituitarism, which is a rare and frequently underdiagnosed condition. Hypopituitarism can be present at birth called congenital or may develop due to acquired causes like tumor, infection, infiltration, vascular or other causes. Symptoms of hypopituitarism are highly dependent on which hormones are insufficient. The present prospective study was designed to test whether treated hypopituitarism is associated with changes in 3DSTE-derived LV strains in patients without known cardiovascular disorder. We investigated 38 patients with treated hypopituitarism who were in sinus rhythm (57.0±13.6 years, 19 males), 6 patients were excluded from the study due to inferior image quality. The remaining patient group consisted of 16 patients with congenital hypopituitarism and 16 patients with acquired form of hypopituitarism. Their results were compared to age- and gender-matched controls (mean age: 55.3±4.7 years, 14 males). Out of the 32 patients with hypopituitarism, 30 patients had growth hormone deficiency, 27 patients had central adrenal insufficiency, 12 patients had central hypothyroidism, 12 patients had hypogonadotropic hypogonadism and 5 patients had diabetes insipidus. Only LV longitudinal and area strains proved to be significantly increased in patients with hypopituitarism, other LV strains did not differ between patients and controls. No significant differences could be confirmed in LV strains between patients with congenital and acquired hypopituitarism. It could be concluded that longitudinal LV strains are increased in both congenital and acquired treated hypopituitarism.

Abstract
Background Dextro-transposition of the great arteries (dTGA) is a rare condition comprising 5–7% of all congenital heart diseases (CHD). Until 1990s, atrial switch operations were the method of choice for the treatment of dTGA. The aim of our present study was to evaluate the abnormalities of the mitral annulus (MA) by three-dimensional speckle-tracking echocardiography (3DSTE). Potential differences in MA dimensions and functional properties late after Senning- and Mustard-procedures were analyzed as well. Methods This retrospective cohort study comprised 19 dTGA patients late after atrial switch operation, from which 7 subjects were not involved due to inferior image quality. The remaining dTGA patient group comprised 12 subjects (age: 30.7±8.6 years, 7 males). For comparisons, 32 age- and gender-matched healthy controls were evaluated (age: 34.4±12.3 years, 18 males). Results End-systolic and end-diastolic MA diameter (MAD), area and perimeter proved to be increased, while MA functional parameters [MA fractional area change (MAFAC) and fractional shortening (MAFS)] were reduced in all dTGA patients as compared to matched controls regardless of the atrial switch procedure used. However, MA morphological parameters were tendentiously lower, while MA functional parameters were tendentiously favorable in case of Senning-procedure compared to Mustard-procedure. Conclusions dTGA is accompanied by MA dilation and its functional impairment late after Senning- and Mustard-procedures.

Tricuspid annular abnormalities following different surgical strategies in adults with corrected tetralogy of Fallot (Results from the CSONGRAD Registry and MAGYAR-Path Study). Cardiovasc Diagn Ther 2021; 11:1276-1283. [PMID: 35070797 PMCID: PMC8748490 DOI: 10.21037/cdt-21-256] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Accepted: 07/16/2021] [Indexed: 10/20/2023]
Abstract
BACKGROUND Although there is an increasing number of patients with corrected tetralogy of Fallot (cTOF), who reach adulthood due to recent successful surgical procedures, some of them suffers from late complications, including functional tricuspid regurgitation (FTR). The purpose of the present study was to examine tricuspid annular (TA) abnormalities in adult cTOF patients and their relationship right atrial (RA) volumes respecting the cardiac cycle assessed by three-dimensional speckle-tracking echocardiography (3DSTE). Moreover, the effect of different surgical procedures on TA morphologic and functional parameters was examined as well. METHODS The study comprised 24 cTOF patients (32.8±13.5 years, 9 males) in which early palliative surgery and late total correction were performed in 12 cases (pcTOF), while early total reconstruction was performed in 12 subjects (etrTOF). Their results were compared to those of 33 matched healthy adults (36.7±7.2 years, 15 males). RESULTS Dilated end-systolic and end-diastolic TA morphologic parameters and their body surface area-indexed counterpart could be detected in cTOF patients as compared to that of controls. TA fractional area change and TA fractional shortening proved to be reduced in cTOF patients as well as in etrTOF and pcTOF patients compared to controls. None of the TA morphologic and functional parameters showed any differences between etrTOF and pcTOF patients. Increased maximum, preatrial contraction and minimum RA volumes could be detected in cTOF patients compared to controls, which correlated with TA dimensions. CONCLUSIONS TA is dilated with reduced function in adult patients with cTOF. TA dilation is related to RA volumes. etrTOF and pcTOF patients have similar TA dimensions and TA functional properties.

Abstract
Introduction: Hypopituitarism is a rare, often underdiagnosed, complex hormonal disease caused by the decreased secretion of one or more hormones in the pituitary gland. The present study was designed to assess left ventricular (LV) rotational mechanics in patients with treated hypopituitarism. It was also aimed to find possible differences in these parameters according to the origin of hypopituitarism (congenital vs. acquired). Methods: The present prospective study involved 35 treated patients with hypopituitarism; however, 4 patients had to be excluded due to inferior image quality. The mean age of the remaining 31 cases was 56.3 ± 13.2 years (18 males). The control group consisted of 29 age- and sex-matched healthy volunteers (mean age: 55.3 ± 4.8 years, 14 males). In all cases a complete two-dimensional echocardiography examination was performed followed by three-dimensional speckle-tracking echocardiography. Results: No significant differences could be found in LV volumes between the controls and patients with hypopituitarism and hypopituitary subgroups. LV apical rotation (8.1 ± 5.1° vs. 10.6 ± 3.5°, p < 0.05) and LV twist (11.9 ± 5.3° vs. 15.1 ± 3.8°, p < 0.05) were impaired in the hypopituitary group with normally directed LV rotational mechanics as compared to the healthy controls. However, 13% of patients showed a near absence of LV twist called LV "rigid body rotation" (LV-RBR). There were no significant differences regarding LV apical and basal rotations and twist between acquired and congenital hypopituitary subgroups. Conclusions: Impaired LV apical rotation and twist could be demonstrated in hypopituitarism regardless of its origin. In the present study with small number of patients with hypopituitarism, LV-RBR was present in 13% of cases.

Abstract
INTRODUCTION Little is known about the relationship between left atrium (LA) volumes and contractility features along the cardiac cycle. The present study aimed to assess, by three-dimensional speckle-tracking echocardiography (3DSTE), correlations between LA volumes, volume-based functional properties, and strains during the cardiac cycle in healthy adults. METHODS We included 217 healthy adult volunteers (mean age 33.4 ± 12.7 years, 112 males) who underwent complete two-dimensional Doppler echocardiography with 3DSTE. RESULTS LA stroke volumes were greater in subjects with the greater maximum LA volume (Vmax ) in reservoir, conduit, and booster pump phases of LA function. While LA emptying fraction in LA reservoir phase was not different between subjects depending in their Vmax value, a significantly lower LA emptying fraction could be detected in LA conduit phase in subjects whose Vmax was >50 mL. In booster pump function, LA emptying fraction was not significantly different whatever the Vmax . Only global and mean segmental peak LA radial strain (RS) and 3D strain (3DS) and the same strains at atrial contraction appeared greater in subjects with greater Vmax , whereas the other strain parameters were not different. CONCLUSIONS In healthy subjects, LA-RS and LA-3DS, objective features of LA contractility, are greater in subjects with greater LA volumes up to a point beyond which this association disappears.

Abstract
Aims Lower body half compression of bilateral secondary leg lymphoedema (LE) without relevant cardiac insufficiency gives rise to whether external leg compression may influence left ventricular (LV) function. Patients with LE were subjected to baseline two‐dimensional transthoracic echocardiography (2DTTE) for general assessment then three‐dimensional speckle‐tracking echocardiography (3DSTE) before and 1 h after lower body half external compression for LV torsion analysis. Methods and results Baseline 2DTTE was performed in the cohort of 25 LE patients, and the results were compared with those of age‐ and gender‐matched 52 healthy controls (mean age: 47.8 ± 12.8 vs. 40.7 ± 14.0 years, 24 women/1 man vs. 49 women/3 men, respectively). 3DSTE was conducted for the assessment of LV rotational mechanics where apical (AR), and basal rotations (BR) were measured before and 1 h after the use of compression class 2 (ccl 2) flat‐knitted medical compression pantyhoses (pressure range: 23–32 mmHg). 2DTTE showed significantly larger LV end‐diastolic volume and ejection fraction among LE patients compared with control subjects (108.3 ± 20.1 vs. 98.5 ± 21.7 mL, 69.8 ± 4.8 vs. 65.5 ± 4.3%, respectively) and notably smaller LV end‐systolic diameter and posterior wall thickness (28.9 ± 3.5 vs. 31.2 ± 3.4 mm, 8.1 ± 1.0 vs. 9.0 ± 1.7 mm, respectively). The results of 20 patients with LE were considered in 3DSTE examinations due to the drop‐out of five probands with technical failures. The data of four LE patients showing significant LV rotational abnormalities were managed separately, and the rotational parameters of the remaining sixteen patients did not differ significantly from those of matched controls except significant reduction of LV BR following the application of medical compression stockings (MCS) (−2.70 ± 1.26 degrees after 1 h use of pantyhose in patient group vs. −4.28 ± 2.18 degrees of the control group; P < 0.05). Conclusions The application of compression pantyhoses moderately but significantly decreased LV BR without a remarkable impact on twisting mechanism in LE patients in the absence of LV rotational abnormalities.

Abstract
INTRODUCTION A number of studies defined normal reference values of three-dimensional (3D) speckle-tracking echocardiography (3DSTE)-derived left ventricular (LV) strains. The present study aimed to quantify normal reference values of LV strains in healthy adult population in real clinical world settings in different age groups, and to determine age- and gender-dependence of these variables in a high volume single center. METHODS The present prospective study included 296 healthy adult subjects. Among them, 124 were excluded due to inferior image quality during the 6-year recruitment period (2011-2017). The remaining population was further divided into four subgroups based on age decades. RESULTS While global radial (RS) strain showed an increase-decrease-increase pattern with age, circumferential, longitudinal, and area strains (CS, LS, AS, respectively) were nonsignificantly lower in older ages. Only global LV-LS showed gender-dependency with higher values in females. Although moderately higher RS and 3DS and lower LS, and AS were observed in males, clear gender-dependency could not be detected in different age decades. CONCLUSIONS This study provides normal reference values of 3DSTE-derived global, segmental, mean segmental, and regional LV strains in healthy adult subjects based on real-life clinical experience. Age-, gender-, and functional nonuniformity of LV strains were also defined.

Abstract
Background The left ventricle (LV) is the pump of the peripheral circulation, therefore its non-invasive accurate volumetric and functional assessment is essential. Three-dimensional (3D) speckle-tracking echocardiography (STE) is a new tool with capability of quantification of LV volumes and ejection fraction (EF). In the present study, age- and gender-dependency of 3DSTE-derived LV volumetric parameters were aimed to be quantified in healthy adults. Methods The present study involved 298 healthy adults. Data acquisition took place over a 6 year period (2011-2017), during which 123 adults had to be excluded due to inferior image quality. The study population was further divided into 4 groups based on age decades. In every case, a complete two-dimensional echocardiography was performed followed by 3DSTE examination. Results No significant differences were detected between the different age groups regarding 3D end-diastolic volume (EDV) and 3D end-systolic volume (ESV) and their body surface area (BSA)-indexed counterpart. 3DEF differed significantly between the 30-39-year-old males and 40-49-year-old males (P=0.04). Between the youngest and oldest patient group, only 3D left ventricular mass (LVM) was significantly different (P=0.02). The 18-29-year-old females had a significantly different 3DLVM (P<0.001) compared to that of the 50+ year-old females. Between the 40-49-year-old and 50+ year-old females 3DLVM (P=0.02) and BSA-indexed 3DLVM (P=0.05) proved to be significantly different. Conclusions 3DSTE seems to be a reasonably viable tool for the quantification of LV volumetric parameters.

Abstract
Background Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease (CHD). Abnormal aortic dimensions and elasticity parameters have been long described for corrected TOF (cTOF) together with left ventricular (LV) rotational abnormalities, but results are conflicting. The present study focuses on investigating LV rotational mechanics in cTOF, and possible correlation of these parameters with aortic elasticity. It was also aimed to be examined whether different surgical strategies have any effect on these results. Methods The study involved 26 adult cTOF patients, from which 14 had palliative surgery first and a late total correction (pcTOF), while early total correction was the treatment of choice in 12 patients (etrTOF). Their results were compared to those of 37 age- and gender-matched healthy adults. Routine transthoracic two-dimensional Doppler echocardiography extended with assessment of aortic elastic properties and three-dimensional speckle-tracking echocardiography (3DSTE) was performed in all cTOF patients and controls. Results Sixteen out of 26 cTOF patients showed normally directed LV rotational mechanics, while apical or basal LV rotations were in the same clockwise or counterclockwise directions in 7 and 3 cTOF cases, respectively (LV 'rigid body rotation', RBR). Significantly reduced LV apical rotation and twist could be demonstrated in all cTOF patients with preserved LV basal rotation regardless of previous procedure. pcTOF patients showed significantly reduced LV apical rotation as compared to that of etrTOF cases. Significant correlations could be demonstrated between LV apical rotation and aortic stiffness index (r=-0.55, P=0.03) and aortic distensibility (r=0.52, P=0.04). Conclusions Significant LV rotational abnormalities could be demonstrated in cTOF with the high prevalence of LV-RBR. pcTOF patients showed significantly reduced LV apical rotation as compared to that of etrTOF cases. Unexpected abnormal physiologic response of LV rotational mechanics to increased aortic stiffness can be detected in cTOF patients without LV-RBR.

Abstract
Background Aortopathy is a common phenomenon in tetralogy of Fallot (TOF). The current study was designed to detect left ventricular (LV) deformation abnormalities and its relation to aortic stiffness in corrected TOF (cTOF) using the novel three-dimensional (3D) speckle-tracking echocardiography (3DSTE). Detailed comparative analysis between patients with early palliation-late correction (pcTOF) and early total reconstruction (etrTOF) was also performed. Methods The present study consisted of 28 cTOF patients (35.0±15.7 years, 11 males) from which 15 and 13 proved to be pcTOF and etrTOF, respectively. Their clinical parameters were compared to those of 39 matched healthy adults (35.5±6.0 years, 16 males). Results cTOF patients showed significantly lower global LV longitudinal, circumferential and area strains as compared to controls. In etrTOF patients, global LV 3D strain was higher than in controls. In pcTOF patients, all LV strains proved to be significantly lower as compared to those of etrTOF patients and controls. In all cTOF patients, several moderate correlations could be detected between LV strain parameters and aortic elastic properties. Conclusions Significant LV deformational abnormalities could be demonstrated in cTOF patients. etrTOF patients have beneficial LV strain parameters as compared to those of pcTOF patients. LV strains show correlations with aortic elastic properties.

Abstract
INTRODUCTION There is a limited number of echocardiographic studies determining mitral annular (MA) dimensions in healthy subjects. The present study aimed to establish normal reference values of three-dimensional speckle-tracking echocardiography-derived MA dimensions and functional properties in healthy adults in relation with age and gender. METHODS The present study comprised 298 healthy adult subjects. From this population, 94 subjects were excluded due to inadequate image quality. Therefore the remaining group consisted of 204 subjects with the mean age of 33.88 ± 12.97 years (107 males). The population sample was further divided into age categories: 18-29 years (n = 105; mean age: 24.11 ± 2.98 years, 51 males), 30-39 years (n = 44; mean age: 33.80 ± 2.39 years, 31 males), 40-49 years (n = 19; mean age: 43.47 ± 3.18 years, 11 males) and ≥50 years of age (n = 36, mean age: 57.42 ± 6.11 years, 14 males). RESULTS End-diastolic MA dimensions did not change significantly during the decades. End-systolic MA diameter, area, and perimeter were larger over the age of 50 years than in the 18-29 year-old group. MA fractional area change was found smaller over the age of 50 years than in 18-29-year-old group. While end-diastolic MA variables did not show gender-differences, end-systolic MA area and perimeter were lower in females in the 18-29-year-old group. CONCLUSIONS End-systolic MA dimensions change over decades, resulting in a special pattern of MA functional properties with significant reduction over the age of 50 years.

Rev Port Cardiol 2021; 40:253-258. [PMID: 33663867 DOI: 10.1016/j.repc.2020.07.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Revised: 06/11/2020] [Accepted: 07/08/2020] [Indexed: 10/22/2022] Open
Abstract
INTRODUCTION AND OBJECTIVE Acromegaly is a rare, chronic and slowly developing endocrine disorder caused by hypersecretion of human growth hormone and consequently of insulin-like growth factor-1 during adulthood. The present study was conducted to assess mitral annular (MA) size and function between acromegalic patients and age- and gender-matched healthy controls by three-dimensional speckle-tracking echocardiography (3D-STE). It also aimed to examine whether activity of the disease has any effect on MA parameters. METHODS This study included 27 patients with acromegaly, three of whom were excluded due to inferior image quality. The mean age of the remaining 24 patients was 55.7±14.0 years and seven were male. Complete two-dimensional Doppler echocardiography and 3D-STE were performed in all cases. RESULTS Significantly increased end-diastolic and end-systolic MA diameter (2.81±0.36 cm vs. 2.44±0.34 cm and 2.00±0.32 cm vs. 1.65±0.37 cm, respectively), area (9.67±2.33 cm2 vs. 7.38±1.93 cm2 and 5.14±1.62 cm2 vs. 3.74±1.19 cm2, respectively) and perimeter (11.76±1.42 cm vs. 10.27±1.33 cm and 8.61±1.23 cm vs. 7.36±1.10 cm, respectively) were demonstrated in acromegalic patients compared with control subjects. MA functional parameters were not significantly altered compared to those of healthy individuals. CONCLUSIONS MA dilation could be seen in acromegaly regardless of its activity. Acromegaly is not associated with MA functional impairment.

Abstract
BACKGROUND In normal circumstances while left ventricular (LV) apex rotates counterclockwise, LV base has a clockwise movement at the same time. This sort of towel-wringing-like movement is called LV twist. The present study was designed to test whether differences in LV rotational mechanics could be detected in elite athletes doing high dynamic sports with different static components in their training. METHODS The subject group comprised 80 elite sportsmen. The following groups were created regarding their physical activity: group CI (high dynamic/low static)(N.=13, mean age: 24.0±5.1 years, group CII (high dynamic/moderate static)(N.=23, mean age: 24.6±7.7 years) and group CIII (high dynamic/high static)(N.=34, mean age: 22.8±6.0 years). Their results were compared to 67 age- and gender-matched non-athletic healthy controls (mean age: 24.0±5.1 years). Three-dimensional speckle-tracking echocardiography was used for the evaluation of LV rotational abnormalities. RESULTS Reduced LV basal rotation was seen in group CII and CIII subjects compared to the control group (-4.31±1.82 degrees vs. -3.17±2.81 degrees and -2.88±1.88 degrees, P<0.05 and P<0.05, respectively). It was accompanied with LV twist reduction in groups CII and CIII subjects compared to the control group (14.0±3.4 degree vs. 11.3±4.3 degrees and 11.5±4.1 degrees, P<0.05 and P<0.05, respectively). None of the elite athletes showed absence of LV twist called as LV "rigid body rotation." CONCLUSIONS Significant LV rotational abnormalities including reduced LV basal rotation and twist could be detected in elite athletes doing high dynamic sports with moderate/high static components in their training.

Normal reference values of left atrial volumes and volume-based functional properties using three-dimensional speckle-tracking echocardiography in healthy adults (Insights from the MAGYAR-Healthy Study). JOURNAL OF CLINICAL ULTRASOUND : JCU 2021; 49:49-55. [PMID: 32804419 DOI: 10.1002/jcu.22879] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Revised: 03/26/2020] [Accepted: 05/26/2020] [Indexed: 06/11/2023]
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
Acromegaly and diabetes mellitus (DM) separately are associated with cardiovascular alterations and modified left ventricular (LV) deformation, which can be quantitatively assessed by three-dimensional speckle-tracking echocardiography (3DSTE). The present study aimed to assess the relationship between LV deformation and twist in the presence of DM in acromegaly. Thirty-seven acromegaly patients were involved in the study, but due to insufficient image quality 13 have to be excluded from analysis. Therefore, the present study comprised 24 acromegaly patients, from which 5 had DM. Their data was compared to 35 age- and gender matched healthy controls. Complete two-dimensional Doppler echocardiography extended with 3DSTE were performed in all patients and controls. Only non-diabetic acromegaly cases had increased global and mean segmental LV radial strain, diabetic acromegaly patients had similar LV radial strain as compared to that of healthy subjects. Other LV strain parameters did not show any difference between diabetic and non-diabetic acromegaly patients. While LV basal rotation was similar among the groups, LV apical rotation was reduced in both diabetic and non-diabetic patients as compared to healthy subjects. However, diabetic acromegaly patients had tendentiously higher values. The ratio of absence of LV twist called as LV rigid body rotation was similar between the groups examined. Diabetes mellitus deteriorates left ventricular deformation in acromegaly.

Are increased left ventricular strains compensatory effects in lipedema? Detailed analysis from the three-dimensional speckle-tracking echocardiographic MAGYAR-Path Study. JOURNAL OF CLINICAL ULTRASOUND : JCU 2020; 48:470-475. [PMID: 32394509 DOI: 10.1002/jcu.22855] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 03/26/2020] [Accepted: 04/07/2020] [Indexed: 06/11/2023]
Abstract
PURPOSE Lipedema is a chronic, common but underdiagnosed disease masquerading obesity, with female predominance, characterized by disproportional abnormal adipose tissue distribution of the lower and also upper extremities. The present study was designed to determine whether lipedema is associated with three-dimensional (3D) speckle-tracking echocardiography (3DSTE)-derived left ventricular (LV) deformation abnormalities, and to assess the effects of 1-hour use of medical compression stockings (MCS). METHODS The present study comprised 19 female patients with lipedema (mean age: 42.2 ± 12.4 years), compared to 28 age-matched healthy female controls (mean age: 42.0 ± 9.8 years). RESULTS Lipedema patients showed larger left atrial and LV dimensions and greater LV ejection fraction than controls, without significant difference in other echocardiography variables. Lipedema patients had greater 3DSTE-derived global and mean segmental LV circumferential and area strains than controls. Following 1-hour use of wearing MCS, neither global and nor mean segmental LV strains showed significant impairment or improvement. CONCLUSIONS Increased LV strains could be compensatory effects maintaining LV pumping function in lipedema. Short-term wearing of MCS has no global effect on LV strains.

Abstract
Lipedema is a lymphedema-masquerading symmetrical, bilateral and disproportional obesity. Its conservative maintenance treatment comprises the use of flat-knitted compression pantyhoses. Lipedema is known to be associated with left ventricular morphological and functional alterations. The present study aimed to assess the effects of graduated compression stockings on left ventricular (LV) rotational mechanics measured by three-dimensional speckle-tracking echocardiography (3DSTE) in lipedema patients. The present study comprised twenty lipedema patients (mean age: 45.8 ± 11.0 years, all females) undergoing 3DSTE who were also compared to 51 age- and gender-matched healthy controls (mean age: 39.8 ± 14.1 years, all females). 3DSTE analysis was performed at rest, and subsequent to 1 hour application of compression class 2 made-to-measure flat-knitted pantyhose. Six lipedema patients showed significant LV rotational abnormalities. Of the remaining fourteen lipedema patients LV basal rotation rotation showed significant reduction, while LV apical rotation showed significant increase with unchanged LV twist after a 60-minute use of compression garment. Significant changes in LV rotational mechanics could be detected among 14 women with lipedema after the use of compression garment however six probands have special LV rotational abnormalities at baseline and/or after compression.

Left ventricular apical rotation is associated with mitral annular function in healthy subjects. Results from the three-dimensional speckle-tracking echocardiographic MAGYAR-Healthy Study. Physiol Int 2020; 107:145-154.

Abstract
Introduction Left ventricular (LV) twist is considered an essential part of LV function due to oppositely directed LV basal and apical rotations. Several factors could play a role in determining LV rotational mechanics in normal circumstances. This study aimed to investigate the relationship between LV rotational mechanics and mitral annular (MA) size and function in healthy subjects. Methods The study comprised 118 healthy adult volunteers (mean age: 31.5 ± 11.8 years, 50 males). All subjects had undergone complete two-dimensional (2D) Doppler echocardiography and three-dimensional speckle-tracking echocardiography (3DSTE) at the same time by the same echocardiography equipment. Results The normal mean LV apical and basal rotations proved to be 9.57 ± 3.33 and -3.75 ± 1.98°, respectively. LV apical rotation correlated with end-systolic MA diameter, area, perimeter, fractional area change, and fractional shortening, but did not correlate with any end-diastolic mitral annular morphologic parameters. The logistic regression model identified MA fractional area change as an independent predictor of ≤6° left ventricular apical rotation (P < 0.003). Conclusions Correlations could be detected between apical LV rotation and end-systolic MA size and function, suggesting relationships between MA dimensions and function and LV rotational mechanics.

Abstract
INTRODUCTION The right atrium (RA) roles include being a systolic reservoir, an early diastolic conduit, and a late-diastolic booster pump. The present study aimed to assess normal reference values of three-dimensional speckle-tracking echocardiography (3DSTE)-derived RA volumetric data and volume-based functional properties in healthy adult subjects. METHODS We included 260 healthy adult subjects in sinus rhythm with complete clinical and demographic dataset, but excluded 110 of them because of inferior image quality. The remaining population sample comprised 150 subjects (31.0 ± 11.6 years, 79 males). Complete two-dimensional Doppler echocardiography and 3DSTE have been performed in all subjects. RESULTS Systolic RA volumetric variables did not show changes over time, but after 50 years, a significant reduction could be demonstrated in RA stroke volume and emptying fraction. While early diastolic RA volume increased over time, RA stroke volume and emptying fraction decreased. While late-diastolic RA volume increased over age decades, similar increase could be detected in RA stroke volume but a reduction occurred in older ages. Late-diastolic RA emptying fraction showed an increasing (after the 40s)-decreasing (after the 50s) pattern. CONCLUSIONS Our study provides normal reference values of 3DSTE-derived RA volumes and volume-based functional properties and their age- and gender dependency in healthy adult subjects.
