Cardiac manifestations in juvenile scleroderma or systemic sclerosis (JSSc) have poor prognosis, begin in early stages of the disease, and remain clinically asymptomatic. New echocardiography modalities, such as 2D/3D speckle tracking (STE, strain analysis for regional and global ventricular functions), can detect cardiac involvement in early stages. We assessed 21 JSSc patients and 19 controls using 2D/3D STE. The left ventricular end diastolic volume, end systolic volume, and ejection fraction of the patient and control groups were significantly different (99...

Cardiovascular diseases (CVD) represent the leading cause of maternal mortality and morbidity. Knowledge of CVD in women is constantly evolving and data are emerging that female-specific risk factors as complications of pregnancy are conditions associated with an increased risk for the long-term development of CVD. Echocardiography is a safe and effective imaging technique indicated in symptomatic or asymptomatic pregnant women with congenital heart diseases who require close monitoring of cardiac function...

BACKGROUND: Primary aldosteronism is associated with a higher incidence of left ventricular (LV) hypertrophy and diastolic dysfunction than essential hypertension. However, systolic function via endocardial measurements is similar between patients with primary aldosteronism and essential hypertension. Speckle-tracking echocardiography is a sensitive tool which can detect subclinical impairments in systolic function. The aim of this study was to investigate aldosterone-induced subclinical impairments in systolic function...

BACKGROUND: Interleukin (IL)-12 activity is involved in the pathogenesis of psoriasis and acute coronary syndromes. We investigated the effects of IL-12 inhibition on vascular and left ventricular (LV) function in psoriasis. METHODS AND RESULTS: One hundred fifty psoriasis patients were randomized to receive an anti-IL-12/23 (ustekinumab, n=50), anti-tumor necrosis factor-a (TNF-α; etanercept, n=50), or cyclosporine treatment (n=50). At baseline and 4 months post-treatment, we measured (1) LV global longitudinal strain, twisting, and percent difference between peak twisting and untwisting at mitral valve opening (%untwMVO) using speckle-tracking echocardiography, (2) coronary flow reserve, (3) pulse wave velocity and augmentation index, (4) circulating NT-proBNP (N-terminal pro-B-type natriuretic peptide), TNF-α, IL-6, IL-12, IL-17, malondialdehyde, and fetuin-a...

Cheuk-Man Yu
The advancement of echocardiography in the past two decades is more than downsizing of the machines and improvement of image quality, but introduction of new imaging modalities leading to the ability of performing quantitative analysis. This function is greatly facilitated by the integration of echo machines with high performance computers, software programming and establishment of workstation for offline analysis. Today, echo examination is more than estimation of ejection fraction (EF) and patterns of left ventricular (LV) diastolic dysfunction...

BACKGROUND: Strain analysis is feasible using three-dimensional (3D) echocardiography. This approach provides various parameters based on speckle tracking analysis from one full-volume image of the left ventricle; however, evidence for its volume independence is still lacking. METHODS: Fifty-eight subjects who were examined by transthoracic echocardiography immediately before and after hemodialysis (HD) were enrolled. Real-time full-volume 3D echocardiographic images were acquired and analyzed using dedicated software...

OBJECTIVE: Epirubicin (Epi) is a potent and effective drug for many malignant cancers with serious cardiotoxicity. Therefore, layer-specific two-dimensional speckle tracking echocardiography (2D-STE) was used to evaluate the longitudinal and circumferential systolic function of the left ventricular for the early detection of cardiotoxicity in this retrospective work. METHODS: Overall, 130 female patients with postoperative breast cancer who did not receive radiotherapy were classified into three groups: Group A (control group, n = 40) without any chemotherapy; Group B (n = 44) administered Epi at 180 ~ 240 mg/m(2) ; and Group C (n = 46) administered Epi at ≥360 mg/m(2) ...

Patients with continuous-flow left ventricular assist devices (LVADs) are at elevated risk of developing ventricular arrhythmias (VA), which can result in right ventricular dysfunction and abnormal LVAD function. Predictors of postoperative VA after LVAD placement are unclear. We hypothesized that global left ventricular circumferential strain (LVCS), a marker of transmural impairment in myocardial function, would independently predict postoperative VA in patients who underwent LVAD implantation. We studied 98 consecutive patients (57 ± 11 years, 83% men) who underwent HeartMate II axial flow LVAD placement...

INTRODUCTION: Patients with classical congenital adrenal hyperplasia (CAH) have increased cardiovascular risk, but the vascular and cardiac function during longitudinal corticoids replacement therapy is not known thoroughly. MATERIAL AND METHODS: Cross-sectional study of 19 Caucasian adults with CAH (age 23.7 ± 3.8 years; twelve males) compared to 20 healthy volunteers matched for origin, sex, age, and body mass index (BMI). All of the participants were assessed for flow mediated dilatation of the brachial artery (FMD), intima-media thickness of the common carotid artery (cIMT) and common femoral artery (fIMT), standard echocardiography, and global longitudinal left ventricular function using two-dimensional speckle-tracking echocardiography (LSTE)...

Prevention strategies are important to optimize and to manage heart care in breast cancer survivors. Regular physical activity at moderate intensity is normally proposed to maintain myocardial performance; however, no data is available about the different impact of different levels of physical exercise. 2D speckle tracking echocardiography (2DSTE) is an accepted method for early detection of myocardial dysfunction. The study aims to monitor the cardiac performances in breast cancer survivors by 2DSTE analysis to manage sports activity vs physical activity...

A systematic review and meta-analysis of prospective randomized studies were performed to evaluate the diagnostic value of measuring global longitudinal strain (GLS) using speckle tracking echocardiography (STE) in determining myocardial infarction (MI) size, which is usually measured based on late gadolinium enhancement (LGE) by cardiovascular magnetic resonance (CMR). Eleven trials with a total of 765 patients were included. The pooled correlation was 0.70 (95% CI: 0.64, 0.74) between two-dimensional (2D) GLS and the LGE percentage, and it was 0...

Quantification of cardiac structure and function is central in cardiovascular research. Rabbits are valuable research models of cardiovascular human disease; however, there is little normal data available. The aim of this study was to investigate feasibility and provide normal values for comprehensive echocardiographic assessment of biventricular function in rabbits. New Zealand white rabbits underwent trans-thoracic echocardiography using a general electric (GE) Vivid 7/E9 system with a 10 MHz transducer, under light sedation, to evaluate biventricular function and dimensions...

A registration method to fuse two-dimensional (2-D) echocardiography images with cardiac computed tomography (CT) volume is presented. The method consists of two major procedures: temporal and spatial registrations. In temporal registration, the echocardiography frames at similar cardiac phases as the CT volume were interpolated based on electrocardiogram signal information, and the noise of the echocardiography image was reduced using the speckle reducing anisotropic diffusion technique. For spatial registration, an intensity-based normalized mutual information method was applied with a pattern search optimization algorithm to produce an interpolated cardiac CT image...

BACKGROUND: Women who have coronary artery disease (CAD) often present with atypical symptoms that may lead to misdiagnosis. We assessed strain, systolic strain rate and left ventricular dyssynchrony with 2- dimensional- speckle tracking echocardiography to evaluate its use as a non-invasive method for detecting CAD in women with normal ejection fraction compared with healthy women controls with a normal angiogram. METHODS: We included 35 women with CAD confirmed by coronary angiography and a positive exercise stress echocardiography and 35 women in a control group with a low pretest probability of CAD, normal angiogram and a normal stress echocardiography with normal EF...

BACKGROUND: Late allocation of organs for transplant impairs post liver transplant (LT) survival. Cardiac dysfunction, especially diastolic and autonomic dysfunction, is frequent and plays an important role in the prognosis of cirrhotic patients. However, the role of myocardial contractility is unexplored and its prognostic value is controversially discussed. This study analyses the role of myocardial contractility assessed by speckle tracking echocardiography in LT allocation. METHODS: 168 cirrhotic patients (training cohort: 111, validation cohort: 57) awaiting LT in two centers were included in this retrospective study...

BACKGROUND: Cardiovascular Magnetic Resonance (CMR) imaging is an important modality that allows the assessment of regional myocardial function by measuring myocardial deformation parameters such as strain and strain rate throughout the cardiac cycle. Feature tracking is a promising quantitative post-processing technique that is increasingly used. It is commonly applied to cine-images, in particular Steady State Free Precession (SSFP), acquired during routine CMR examinations. OBJECTIVE: To review the studies that have used feature tracking techniques in healthy subjects or patients with cardiovascular diseases (CVD)...

BACKGROUND: There is still a significant proportion of patients with heart failure who fail to improve after cardiac resynchronization therapy (CRT). The investigators used parametric two-dimensional speckle-tracking echocardiography with polar plots of the amplitude and timing of left ventricular (LV) longitudinal strain to guide implantation of the LV lead, with the aim of increasing CRT response. METHODS: Sixty-four patients who underwent LV lead implantation guided by two-dimensional speckle-tracking echocardiography (study group) and 64 patients treated with standard CRT implantation (control group) were retrospectively analyzed in this study...
