BACKGROUND: Autologous hematopoietic cell transplantation (HCT) is a first-line therapy for prolonging survival in patients with light-chain (AL) amyloidosis. Cardiac involvement is the most important determinant of survival. However, patients with advanced cardiac involvement have often been excluded from HCT because of high risk for transplantation-related mortality and poor overall survival. Whether baseline left ventricular global longitudinal strain (GLS) can provide additional risk stratification and predict survival after HCT in this high-risk population remains unclear...

BACKGROUND: Contrast-enhanced echocardiography (CE) helps to improve image quality in patients with suboptimal acoustic windows. Despite current recommendations, contrast use remains low. The aim of this study was to identify populations that would benefit more from contrast use. METHODS: A total of 176 subjects (137 men; mean age, 60.8 ± 13.7 years) with technically difficult transthoracic echocardiographic studies who received clinically indicated intravenous contrast were prospectively studied...

BACKGROUND: The aim of the present study was to evaluate the clinical importance of echocardiographic coronary flow velocity reserve (CFVR), resting and exercise left ventricular global longitudinal strain (LVGLS), and myocardial work efficiency (MWE) in patients with cardiac amyloidosis (CA). METHODS: The study population comprised 69 subjects: group A, 27 patients with CA confirmed by endomyocardial biopsy (CA positive); group B, 42 healthy control subjects. The amyloid phenotype in group A was as follows: patients with wild-type transthyretin-related amyloidosis (n = 10), carriers of the Danish familial transthyretin amyloidosis mutation with cardiac involvement (n = 5), and patients with amyloid light chain amyloidosis with cardiac involvement (n = 12)...

BACKGROUND: Accurate assessment of global and regional right ventricular (RV) systolic function is challenging. The aims of this study were to confirm the reliability and feasibility of a three-dimensional (3D) speckle-tracking echocardiography (STE) system, using comparison with cardiac magnetic resonance imaging (CMR), and to assess the contribution of regional RV function to global function. METHODS: In a retrospective, cross-sectional study setting, RV volumetric data were studied in 106 patients who were referred for both CMR and 3D echocardiography within 1 month...

BACKGROUND: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) has been proved to effectively rescue patients from refractory cardiogenic shock. The role of the right ventricle in VA-ECMO has been emphasized, but quantitative right ventricular (RV) analysis in this population has been lacking. Three-dimensional echocardiography (3DE) is currently suggested for RV volumetric analysis. The aims of this study were to assess 3DE-derived RV ejection fraction (RVEF) in patients with refractory cardiogenic shock stabilized by VA-ECMO and to explore the association between 3DE-derived RVEF and weaning success as well as the prognosis after the first intent of decannulation...

BACKGROUND: The prognostic value of left ventricular (LV) global strain and twist in patients with left bundle branch block (LBBB) is not fully investigated. The aim of this study was to investigate the association between myocardial strain and twist and cardiovascular events in patients with LBBB, as assessed using two-dimensional speckle-tracking echocardiography. METHODS: A total of 269 patients with LBBB (mean age, 69.5 ± 10.9 years; 46.8% men) were retrospectively identified...

BACKGROUND: The subendocardium is highly vulnerable to damage and is thus affected even in subclinical disease stages. Therefore, methods reflecting subendocardial status are of great clinical relevance for the early detection of cardiac damage and the prevention of functional impairment. The aim of this study was to investigate the potential ability of myocardial strain parameters to evaluate changes within the subendocardium. METHODS: Male 129/Sv mice were injected with isoproterenol (ISO; n = 32) to induce isolated subendocardial fibrotic lesions or saline as appropriate control (n = 15)...

BACKGROUND: A simplified classification of bicuspid aortic valve (BAV) morphology using only the orientation of fused cusps was recently proposed. The aim of this study was to test whether it is useful for showing an association with the type of valvulopathy or aortopathy. METHODS: BAV phenotype was retrospectively classified in 681 patients (mean age, 59 ± 12 years; 424 men) who underwent aortic valve surgery. Each BAV was classified using both dichotomous (right and left coronary cusp fusion [CCF] vs mixed cusp fusion [MCF]) and conventional methods, and its association with the dominant valvulopathy (aortic stenosis [AS] vs regurgitation) and concomitant aortic surgery was analyzed...

BACKGROUND: Gravity affects every aspect of cardiac performance. When gravitational gradients are at their greatest on Earth (i.e., during upright posture), orthostatic intolerance may ensue and is a common clinical problem that appears to be exacerbated by the adaptation to spaceflight. We sought to elucidate the alterations in cardiac performance during preload reduction with progressive upright tilt that are relevant both for space exploration and the upright posture, particularly the preload dependence of various parameters of cardiovascular performance...

BACKGROUND: Three-dimensional (3D) echocardiography directly assesses right ventricular (RV) volumes without geometric assumptions, despite the complex shape of the right ventricle, and accordingly is more accurate and reproducible than the two-dimensional methodology, which is able to measure only surrogate parameters of RV function. Volumetric analysis has been hampered by frequent inability to clearly visualize RV endocardium, especially the RV free wall, in 3D echocardiographic images...

BACKGROUND: The human aorta dilates with advancing age. However, the association between progressive aortic dilation with aging and cardiac remodeling has not been established in studies of community-dwelling adults. The aim of this study was to test the hypothesis that there would be a relationship between aortic size increase over the early adult life span with left ventricular (LV) structural remodeling and subclinical LV dysfunction in middle age, even in the absence of overt cardiovascular and valvular disease...

BACKGROUND: Patients with acute leukemia (AL) have a higher rate of congestive heart failure than patients with other cancers. AL may predispose to cardiac dysfunction before chemotherapy because of high cytokine release or direct leukemic myocardial infiltration. The aims of this study were to evaluate whether AL is associated with abnormalities of myocardial structure and function before chemotherapy and to identify possible risk factors associated with these myocardial changes. METHODS: Using an echocardiographic database, 76 patients with AL and 76 patients without cancer matched for age, gender, hypertension, and the presence of diabetes were retrospectively selected...

BACKGROUND: Intraventricular pressure difference (IVPD), the diastolic suction during early diastole, is known as a useful marker of myocardial diastolic function in adults with different heart diseases, but there are no studies of fetal IVPD. The aim of this study was to determine whether IVPD exists and changes prenatally and whether IVPD correlates with preexisting parameters to evaluate fetal cardiac diastolic function and ventricular dominance. METHODS: Cross-sectional study data (stroke volume, fetal cardiac output, E/A ratio, and myocardial performance index) from 117 healthy fetuses at 17 to 36 weeks of gestation were retrospectively evaluated...

BACKGROUND: Three-dimensional (3D) echocardiography is fundamental for left ventricular (LV) assessment. The aim of this study was to determine discrepancies in 3D LV endocardial tracings and suggest tracing guidance. METHODS: Forty-five 3D LV echocardiographic data sets were traced by three experienced operators, from different centers, according to predefined guidelines. The 3D meshes were compared with one another, and the endocardial areas of discrepancies were identified...

BACKGROUND: Echocardiograms are often obtained after business hours on an urgent or emergent basis to assist in the care of patients with complex presentations. Considerable variation exists among academic medical centers with regard to who performs and interprets these studies, with different levels of cardiology fellow involvement in scanning and/or interpreting. On-call echocardiographic interpretation can be educationally valuable for cardiologists in training but may come at the expense of patient care...
