BACKGROUND: Ultrasound molecular imaging was used to evaluate the therapeutic effects of antioxidant therapy with EUK-207, which has superoxide dismutase and catalase activities, on suppressing high-risk atherosclerotic features. METHODS: Mice with age-dependent atherosclerosis produced by deletion of the low-density lipoprotein receptor and Apobec-1 were studied at 20 and 40 weeks of age. EUK-207 or vehicle was administered for the preceding 8 weeks. Therapy for 28 weeks was also studied for 40-week-old mice...

BACKGROUND: Left atrial (LA) longitudinal strain is a novel parameter used for the evaluation of LA function, with demonstrated prognostic value in several cardiac diseases. However, the extent of load dependency of LA strain is not well known. The aim of this study was to evaluate the impact of acute changes in preload on LA strain, side by side with LA volume, in normal subjects. METHODS: Twenty-five healthy volunteers (13 men; mean age, 31 ± 2 years) were prospectively enrolled, who underwent two-dimensional and three-dimensional echocardiographic imaging during acute stepwise reductions in preload using a tilt maneuver: baseline at 0°, followed by 40° and 80°...

BACKGROUND: The aim of this study was to determine whether long-term patterns of change in adiposity throughout young adulthood are associated with systolic and diastolic function in midlife. METHODS: Participants in the Coronary Artery Risk Development in Young Adults study, a multicenter, population-based cohort, underwent repeated anthropometric assessment (body mass index [BMI], waist circumference, and waist-to-hip ratio) from examination years 0 to 25. At year 25, longitudinal, circumferential, and radial strain and tissue Doppler velocities were assessed by echocardiography...

BACKGROUND: Stress testing helps diagnose heart failure with preserved ejection fraction (HFpEF), but there are no established criteria for quantifying left ventricular (LV) functional reserve. The aim of this study was to investigate whether comprehensive analysis of the timing and amplitude of LV long-axis myocardial motion and deformation throughout the cardiac cycle during rest and stress can provide more informative criteria than standard measurements. METHODS: Velocity, strain, and strain rate traces were measured from all 18 LV segments by echocardiographic myocardial velocity imaging at rest and during semisupine bicycle exercise in 100 subjects aged 69 ± 7 years, including patients with HFpEF and healthy, hypertensive, and breathless control subjects...

BACKGROUND: Obtaining an accurate diagnosis of fetal aortic arch anomalies is often difficult with traditional two-dimensional (2D) sonography. Thus, the aim of this study was to assess the value of three-dimensional (3D) sonography with spatiotemporal image correlation for diagnosing fetal aortic arch anomalies using a novel algorithm for 3D volume analysis. METHODS: Two-dimensional and 3D echocardiographic image data from 300 normal fetuses and 30 fetuses with aortic arch anomalies were retrospectively reviewed...

BACKGROUND: Severe aortic stenosis (AS) is often accompanied by diastolic dysfunction. After aortic valve replacement (AVR), the left ventricle often undergoes considerable reverse remodeling. Despite this, diastolic dysfunction may persist after AVR. The aims of this study were to determine the incidence of elevated left ventricular (LV) filling pressure at rest and during exercise among patients with severe AS after AVR and to describe factors related to elevated LV filling pressure, especially its association with LV and left atrial remodeling and myocardial fibrosis...

BACKGROUND: Ventricular-annular decoupling is thought to exist in all degenerative myxomatous mitral valve (MV) diseases. However, the annular physiology of degenerative MV disease may differ when severe mitral regurgitation (MR) presents at different stages. The aim of this study was to assess differences in mitral annular physiology and surgical effects between early- and late-stage severe MR. METHODS: Three-dimensional (3D) transesophageal echocardiography was performed before and after MV surgery in 74 patients with degenerative MV disease, including 57 with early-stage severe MR (without left ventricular remodeling) and 17 with late-stage MR (with left ventricular remodeling)...

BACKGROUND: Severe aortic stenosis (AS) and severe tricuspid regurgitation (TR) may coexist. The aim of this study was to determine the change in right ventricular (RV) function and TR after surgical aortic valve replacement combined with tricuspid valve repair (SAVR+TVr), transcatheter aortic valve replacement (TAVR), or conservative management and compare outcomes dependent on RV functional parameters and treatment allocation. METHODS: A retrospective analysis was conducted in 147 consecutive patients with severe AS and TR of baseline and 6-month clinical and echocardiographic parameters, including quantitative estimation of RV size and function (end-diastolic and end-systolic areas, tricuspid annular plane systolic excursion, fractional area change, and Tei index)...

BACKGROUND: Mitral valve (MV) prolapse is common in children with Marfan syndrome (MFS) and is associated with varying degrees of mitral regurgitation (MR). However, the three-dimensional (3D) morphology of the MV in children with MFS and its relation to the degree of MR are not known. The goals of this study were to describe the 3D morphology of the MV in children with MFS and to compare it to that in normal children. METHODS: Three-dimensional transthoracic echocardiography was performed in 27 patients (3-21 years of age) meeting the revised Ghent criteria for MFS and 27 normal children matched by age (±1 year)...

BACKGROUND: The prevalence of isolated cleft mitral valve (MV; no concomitant congenital heart disease or degenerative MV disease) with significant mitral regurgitation (MR) diagnosed using two-dimensional echocardiography (2DE) has been reported to be very low. Three-dimensional echocardiography (3DE) has enabled a more comprehensive visualization of the MV and detailed understanding of the mechanisms of MR and can potentially reveal isolated cleft MV that is not recognized with 2DE...

BACKGROUND: Although the primary role of right atrial (RA) size in the diagnosis and risk stratification of precapillary pulmonary hypertension (PH) has been studied, little is known about the clinical significance of RA function. In line with studies assessing left atrial function in heart failure, the aim of this study was to introduce the RA function index (RAFi) and to explore its prognostic power in precapillary PH. METHODS: RA emptying fraction was calculated as (RA end-systolic volume - RA end-diastolic volume) × 100/(RA end-systolic volume)...

BACKGROUND: Aortic valve calcification (AVC) quantification is computed from multidetector computed tomography (MDCT). The aim of this study was to test the hypothesis that three-dimensional (3D) transthoracic echocardiography can be used to provide a bedside method to assess AVC. METHODS: The study included 94 patients (mean age, 78 ± 12 years; mean aortic valve [AV] area, 1.0 ± 0.6 cm2 ) referred for MDCT and echocardiography for AV assessment. Apical 3D full-volume data sets focused on the AV region were acquired during transthoracic echocardiography, and a region-growing algorithm was applied offline to compute 3D transthoracic echocardiographic AVC (AVC-3DEcho)...

BACKGROUND: Supraventricular tachycardia (SVT) is the most common sustained arrhythmia in children. Infants with SVT and ventricular preexcitation (Wolff-Parkinson-White syndrome) are known to have up to 30% prevalence of congenital heart disease (CHD). Infants without ventricular preexcitation who present with SVT at <1 year of age have a similar prevalence of CHD. However, for children without ventricular preexcitation who present with SVT at older ages, the prevalence of CHD is not known...

BACKGROUND: Reliable assessment of aortic stenosis (AS) severity relies on stroke volume (SV) determination using Doppler echocardiography, but it can also be estimated with two-dimensional/three dimensional echocardiography (2DE/3DE). The aim of this study was to compare SV measurements and AS subgroup classifications among the three modalities and determine their prognostic strength in asymptomatic AS. METHODS: We prospectively enrolled 359 patients with asymptomatic AS...
