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.

Nemes A, Kormányos Á. 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.

Abstract
Due to the lifelong nature of diabetes mellitus (DM), it has been demonstrated to have significant effects on patients' morbidity and mortality. The present study aimed to assess the effects of DM on the clinical outcome and survival in patients who underwent percutaneous coronary intervention (PCI) due to myocardial infarction (MI) and to examine the relationship of DM to the type of the MI and to left ventricular (LV) and renal functions. A total of 12,270 patients with ST-elevation MI (STEMI) or non-ST-elevation MI (NSTEMI) were revascularized at our Institution between 2005 and 2013. In this pool of patients, 4388 subjects had DM, while 7018 cases had no DM. In both STEMI and NSTEMI, the 30-day and 1-year survival were worse in diabetic patients as compared to non-diabetic cases. In the patients with DM, NSTEMI showed worse prognosis within 1-year than STEMI similarly to non-diabetic subjects. Regarding survival, the presence of DM seemed to be more important than the type of MI. Regardless of the presence of DM, reduced LV function was a maleficent prognostic sign and DM significantly reduced the prognosis both in case of reduced and normal LV function. Survival is primarily affected by LV function, rather than DM. Worse renal function is associated with worse 30-day and 1-year survival in both cases with and without DM. Considering different renal functions, the presence of DM worsens both short- and long-term survival. Survival is primarily affected by renal function, rather than DM. The results from a high-volume PCI center confirm significant the negative prognostic impact of DM on survival in MI patients. DM is a more important prognostic factor than the type of the MI. However, survival is primarily affected by LV and renal functions, rather than DM. These results could highlight our attention on the importance of recent DM treatment with new drugs including SGLT-2 inhibitors and GLP-1 antagonists with beneficial effects on survival.

Physiological and psychological effects of a 12-week home-based telemonitored training in metabolic syndrome. Front Cardiovasc Med 2023; 9:1075361. [PMID: 36704473 PMCID: PMC9871627 DOI: 10.3389/fcvm.2022.1075361] [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: 10/20/2022] [Accepted: 12/06/2022] [Indexed: 01/12/2023] Open
Abstract
Background Metabolic Syndrome (MetS) increases the risk of cardiovascular diseases (CVD) and affects around one fourth of the population worldwide. In the prevention and treatment regular exercise trainings are inevitable. Providing personal supervision in out/inpatient care settings for such a large target population challenges the healthcare systems, but using telemonitoring of the home-performed trainings could be a promising and widely available option. Objectives The aim of this study was to evaluate the physiological and psychological effects of a 12-week home-based physical training program, telemonitored by widely available fitness devices on parameters of MetS patients. Methods A total of 55 MetS patients (mean age 49.19 ± 7.93 years) were involved in the study. They were asked to perform 3-5 sessions of exercise activity (min. 150 min) each week for 12 weeks. Trainings were monitored off-line by heart rate sensors, a fitness application and a cloud-based data transfer system. Physiotherapists supervised, coached, and feedback the trainings through an online coach system. We investigated different anthropometric parameters, maximum exercise and functional capacity levels, laboratory parameters, the level of depression, insomnia, vital exhaustion, and wellbeing as well. Results The average weekly training time was 152.0 ± 116.2 min. Out of the 55 participants who completed the program, 22 patients (40%) performed the recommended 150 min or more weekly. Patients showed statistically significant changes in: all the measured waist and hip circumferences; 6-min walk distance (6MWD; from 539.69 ± 78.62 to 569.72 ± 79.96 m, p < 0.001); maximal exercise capacity (11.02 ± 2.6 to 12.14 ± 2 MET, p < 0.001), stress-electrocardiogram duration time (13.74 ± 3.29 to 15.66 ± 2.64 min, p < 0.001); body weight (98.72 ± 21.7 to 97.45 ± 21.76 kg, p = 0.004); high-density lipoprotein cholesterol (n = 45, 1.28 ± 0.31 to 1.68 ± 0.36 mmol/L, p < 0.001); fasting plasma glucose (FPG; n = 47, 6.16 ± 1.26 to 5.44 ± 1.31 mmol/L, p = 0.001); glycated hemoglobin A1c (HbA1c; n = 41, 6.22 ± 0.68 to 5.87 ± 0.78%, p = 0.01). Out of the 55 patients who finished the program 38 patients (70%) completed all the psychological questionnaires. We found statistically significant decrease of the overall scores of the Maastricht Vital Exhaustion Questionnaire, from 3.37 ± 2.97 points to 2.63 ± 2.70 points (p < 0.05) and a significant increase of the overall scores of the WHO Wellbeing Scale from 9.92 ± 2.59 points to 10.61 ± 2.76 points (p < 0.05). We have not found any statistically significant changes in the scores of the Beck Depression Inventory and the Athens Insomnia Scale. Conclusion A 12-week home-based telemonitored training supported by an affordable, commonly available device system produces positive, statistically significant changes in many core components in MetS patients. Telemonitoring is a cheap method for coaching and feeding back the home-based interventions.

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.

Abstract
Global land use change has resulted in more pasture and cropland, largely at the expense of woodlands, over the last 300 years. How this change affects soil hydraulic function with regard to feedbacks to the hydrological cycle is unclear for earth system modelling (ESM). Pedotransfer functions (PTFs) used to predict soil hydraulic conductivity (K) take no account of land use. Here, we synthesize >800 measurements from around the globe from sites that measured near-saturated soil hydraulic conductivity, or infiltration, at the soil surface, on the same soil type at each location, but with differing land use, woodland (W), grassland (G) and cropland (C). We found that texture based PTFs predict K reasonably well for cropland giving unbiased results, but increasingly underestimate K in grassland and woodland. In native woodland and grassland differences in K can usually be accounted for by differences in bulk density. However, heavy grazing K responses can be much lower indicating compaction likely reduces connectivity. We show that the K response ratios (RR) between land uses vary with cropland (C/W = 0.45 [W/C = 2.2]) and grassland (G/W = 0.63 [W/G = 1.6]) having about half the K of woodland.

J Clin Med 2022; 11:jcm11236916. [PMID: 36498491 PMCID: PMC9740525 DOI: 10.3390/jcm11236916] [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: 10/05/2022] [Revised: 10/24/2022] [Accepted: 11/22/2022] [Indexed: 11/25/2022] Open
Abstract
Background: Once occluded, the radial artery becomes unsuitable for repeat interventions and obligates the need for alternative vascular access, such as the femoral approach, which is not encouraged by current guidelines. With the dissemination of distal radial access (DRA), which allows the cannulation of the artery in its distal segment and which remains patent even in the case of radial artery occlusion (RAO), the option to perform angioplasty at this level becomes feasible. Methods: Thirty patients with RAO were enrolled in this pilot study. Recanalization was performed through DRA using hydrophilic guidewires. The feasibility endpoint was procedural success, namely the successful RAO recanalization, the efficacy endpoint was patency of the artery at 30 days, and the safety endpoint was the absence of periprocedural vascular major complications or major adverse cardiac and cerebrovascular events. Results: The mean age of the patients was 63 ± 11 years, and 15 patients (50%) were men. Most patients had asymptomatic RAO (n = 28, 93.3%), and only two (6.6%) reported numbness in their hands. The most common indication for the procedure was PCI (19, 63.2%). Total procedural time was 41 ± 22 min, while the amount of contrast used was 140 ± 28 mL. Procedural success was 100% (n = 30). Moreover, there were no major vascular complications (0%); only two small hematomas were described (10%) and one had an angiographically visible perforation (3%). One case of periprocedural stroke was reported (3%), with onset immediately after the procedure and recovering 24 h later. Twenty-seven radial arteries (90%) remained patent at the one-month follow-up. Conclusions: RAO recanalization is feasible and safe, and by using dedicated hydrophilic guidewires, the success rate is high without significantly increasing procedural time or the amount of used contrast.

Abstract
Abstract
Background
Atherosclerosis is a systemic arterial disease with heterogeneous involvement in all vascular beds, however studies examining the relationship between coronary and radial artery calcification are lacking.
The purpose of this study was to assess the relationship between the two sites and the prognostic value of radial artery calcification (RC) for coronary artery disease.
Methods and results
This is a single-center, retrospective cross-sectional study based on doppler ultrasound of radial artery (RUS) and coronary artery angiography (CAG). We included a total of 202 patients undergoing RUS during distal radial access and CAG at the same procedure, between December 2020 and May 2021, from which 103 were found having RC during RUS (RC-group) and 99 without (NRC-group). Coronary calcifications were evaluated either by angiography examination (moderate and severe), positive CT (>100 Agatson units) or intracoronary imaging (IVUS, OCT). A significant correlation was observed between radial calcification and coronary calcification variables (67.3%, vs 32.7% – p=0.001). The correlation between risk factors such as age, smoking, chronic kidney disease and diabetes mellitus was higher while sex did not play a role. The need of PCI and/or CABG was higher in the RC-group (60% vs 44%, p=0.02). RC therefore predicts the extent and severity of coronary artery disease.
Conclusion
RC may be frequently associated with calcific coronary plaques. These findings highlight the potential beneficial examination of radial arteries whenever CAD is suspected.

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.

Introduction
Polycystic ovary syndrome (PCOS) is a multifactorial, endocrine disease associated with metabolic disturbances (e.g. hyperinsulinemia, insulin resistance) and increased cardiovascular risk. Recent data strongly suggest that different QT variability parameters characterizing cardiac repolarization instability represent novel markers in proarrhythmic risk assessment.
Purpose
In the present study we investigated ECG repolarization parameters, including QT variability parameters in patients with polycystic ovary syndrome.
Methods
Fifty-five PCOS patients (age: 29±6 years) and 55 age-matched healthy volunteers (age: 29±10 years) were enrolled in the study. Five-minute 12-lead resting electrocardiograms were recorded, the ECGs were digitized and evaluated off-line using the Cardiosys-A01 system (Cardiosys-A01, MDE Heidelberg GMBH, Heidelberg, Germany). The following parameters were determined: the frequency corrected QT interval (QTc) using Bazett’s, Fridericia, Framingham and the Hodges formulas; QT dispersion (QTd) and T wave peak-to-end distance (Tpeak-Tend). Among QT variability parameters we analyzed the QT variance (QTv), the QT variability index (QTVI), the short-term beat-to-beat QT and RR interval variability (STV-QT, STV-RR) based on constructed Poincaré plots and the variability ratio (VR).
Results
The RR interval did not differ significantly in PCOS patients compared to controls (821±129 ms vs. 847±99 ms), however the QT interval (373±30 ms vs. 391±27 ms, p<0.01), the QTc calculated with Bazett’s, Framingham, Fridericia and Hodges correction formulas (QTc Bazett’s: 413±18 ms vs. 426±21 ms, p<0.01) and the Tpeak-Tend intervals were significantly shorter (76±10 ms vs. 83±12 ms, p<0.01). The QTd, QTv, and STV-RR did not differ significantly. However, the VR (0.3±0.4 vs. 0.2±0.2, p<0.05), the QTVI (-0,9±0.5 vs. -1,3±0.4, p<0.001), and importantly, the STV-QT were significantly higher in PCOS patients compared to controls (4.0±0.9 ms vs. 3.2±0.9 ms, p<0.0001).
Conclusion
Some of the alterations in repolarization parameters and the significant increase in the short-term beat-to-beat QT interval variability and the QT variability index may indicate increased repolarization instability in patients with polycystic ovary syndrome compared to age-matched controls, however, further studies are needed to establish the exact relation of this finding to increased arrhythmia propensity in this population.

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.

Introduction
Polycystic ovary syndrome (PCOS) is a multifactorial, endocrine disease associated with metabolic disturbances (e.g. hyperinsulinemia, insulin resistance) and increased cardiovascular risk. Recent data strongly suggest that different QT variability parameters characterizing cardiac repolarization instability represent novel markers in proarrhythmic risk assessment.
Purpose
In the present study we investigated ECG repolarization parameters, including QT variability parameters in patients with polycystic ovary syndrome.
Methods
Fifty-five PCOS patients (age: 29±6 years) and 55 age-matched healthy volunteers (age: 29±10 years) were enrolled in the study. Five-minute 12-lead resting electrocardiograms were recorded, the ECGs were digitized and evaluated off-line using the Cardiosys-A01 system (Cardiosys-A01). The following parameters were determined: the frequency corrected QT interval (QTc) using Bazett’s, Fridericia, Framingham and the Hodges formulas; QT dispersion (QTd) and T wave peak-to-end distance (Tpeak-Tend). Among QT variability parameters we analyzed the QT variance (QTv), the QT variability index (QTVI), the short-term beat-to-beat QT and RR interval variability (STV-QT, STV-RR) based on constructed Poincaré plots and the variability ratio (VR).
Results
The RR interval did not differ significantly in PCOS patients compared to controls (821±129 ms vs. 847±99 ms), however the QT interval (373±30 ms vs. 391±27 ms, p<0.01), the QTc calculated with Bazett’s, Framingham, Fridericia and Hodges correction formulas (QTc Bazett’s: 413±18 ms vs. 426±21 ms, p<0.01) and the Tpeak-Tend intervals were significantly shorter (76±10 ms vs. 83±12 ms, p<0.01). The QTd, QTv, and STV-RR did not differ significantly. However, the VR (0.3±0.4 vs. 0.2±0.2, p<0.05), the QTVI (-0,9±0.5 vs. -1,3±0.4, p<0.001), and importantly, the STV-QT were significantly higher in PCOS patients compared to controls (4.0±0.9 ms vs. 3.2±0.9 ms, p<0.0001).
Conclusion
Some of the alterations in repolarization parameters and the significant increase in the short-term beat-to-beat QT interval variability and the QT variability index may indicate increased repolarization instability in patients with polycystic ovary syndrome compared to age-matched controls, however, further studies are needed to establish the exact relation of this finding to increased arrhythmia propensity in this population.

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.

Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) is common in congenital heart disease (CHD). Because clinical-trial data on PAH associated with CHD (PAH-CHD) remain limited, registry data on the long-term course are essential. This analysis aimed to update information from the COMPERA-CHD registry on management strategies based on real-world data. METHODS The prospective international pulmonary hypertension registry COMPERA has since 2007 enrolled more than 10,000 patients. COMPERA-CHD is a sub-registry for patients with PAH-CHD. RESULTS A total of 769 patients with PAH-CHD from 62 specialized centers in 12 countries were included into COMPERA-CHD from January 2007 through September 2020. At the last follow-up in 09/2020, patients [mean age 45.3±16.8 years; 512 (66%) female] had either post-tricuspid shunts (n=359; 46.7%), pre-tricuspid shunts (n=249; 32.4%), complex CHD (n=132; 17.2%), congenital left heart or aortic valve or aortic disease (n=9; 1.3%), or miscellaneous CHD (n=20; 2.6%). The mean 6-minute walking distance was 369±121 m, and 28.2%, 56.0%, and 3.8% were in WHO functional class I/II, III or IV, respectively (12.0% unknown). Compared with the previously published COMPERA-CHD data, after 21 months of follow-up, the number of included PAH-CHD patients increased by 91 (13.4%). Within this group the number of Eisenmenger patients rose by 39 (16.3%), the number of "Non-Eisenmenger PAH" patients by 45 (26.9%). Currently, among the 674 patients from the PAH-CHD group with at least one follow-up, 450 (66.8%) received endothelin receptor antagonists (ERA), 416 (61.7%) PDE-5 inhibitors, 85 (12.6%) prostacyclin analogues, and 36 (5.3%) the sGC stimulator riociguat. While at first inclusion in the COMPERA-CHD registry, treatment was predominantly monotherapy (69.3%), this has shifted to favoring combination therapy in the current group (53%). For the first time, the nature, frequency, and treatment of significant comorbidities requiring supportive care and medication are described. CONCLUSIONS Analyzing "real life data" from the international COMPERA-CHD registry, we present a comprehensive overview about current management modalities and treatment concepts in PAH-CHD. There was an trend towards more aggressive treatment strategies and combination therapies. In the future, particular attention must be directed to the "Non-Eisenmenger PAH" group and to patients with complex CHD, including Fontan patients.

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.
