BACKGROUND: Serial echocardiographic studies in chronic Chagas cardiomyopathy are scarce. The aims of this study were to evaluate whether therapy with benznidazole modifies the progression of cardiac impairment and to identify baseline echocardiographic parameters related to prognosis. METHODS: A prospective substudy was conducted in 1,508 patients with chronic Chagas cardiomyopathy randomized to benznidazole or placebo, who underwent two-dimensional echocardiography at enrollment, 2 years, and final follow-up (5...

Today, Doppler echocardiography is central to our ability to determine cardiovascular hemodynamics, especially in valvular heart diseases, noninvasively. Continuous-wave Doppler (CWD) plays a central diagnostic role in the diagnosis and management of patients with aortic stenosis. The development and use of CWD in aortic stenosis was due to the pioneering work of Dr. Liv Hatle and her outstanding medical and engineering colleagues in Norway. The author was fortunate to be the first to use the early CWD instruments in North America...

BACKGROUND: Left ventricular (LV) mechanics in patients with different single morphologic LV subtypes, including tricuspid atresia, double-inlet left ventricle, and pulmonary atresia with intact ventricular septum, remain poorly studied. Given that histologic studies indicate differences in LV myocardial fiber orientation, we hypothesized that this may result in altered LV mechanics. The aim of this study was to evaluate the influence of LV morphology on LV mechanics. METHODS: Fifty-two children with single left ventricles after Fontan operation and age-matched control subjects were prospectively enrolled...

BACKGROUND: The aim of this study was to investigate whether speckle-tracking echocardiography (STE) improves the detection of myocardial infarction (MI) over visual assessment of systolic wall motion abnormalities (SWMAs) using delayed enhancement cardiac magnetic resonance imaging as a reference. METHODS: Transthoracic echocardiography was performed in 95 patients with first ST segment elevation MI 110 days (interquartile range, 97-171 days) after MI and in 48 healthy control subjects...

BACKGROUND: In normal left ventricles, clockwise basal rotation and counterclockwise apical rotation result in systolic torsion. Torsion is important for contractile efficiency and may be especially important in single-ventricle (SV) physiology. However, little is known about torsion in patients with SVs. The aim of this study was to measure torsion in SVs and to determine its relationship with other measures of ventricular function. The hypothesis was that torsion would be decreased in all SVs, most significantly in single right ventricles, and that it would correlate with other measures of ventricular function...

BACKGROUND: Neovascularization is a marker of plaque vulnerability that can be assessed noninvasively using contrast-enhanced ultrasound (CEUS). The presence and extent of plaque neovascularization and their relation to cardiovascular risk factors and treatments were assessed in asymptomatic patients with carotid stenosis of intermediate severity and no indication for revascularization. METHODS: Sixty-six patients aged 69 ± 8 years (59% men) were prospectively enrolled...

In the 1970s, as cardiac imaging matured from M-mode to two-dimensional echocardiography, investigators in Norway showed that continuous-wave Doppler ultrasonography could be used to accurately measure the mean gradient and pressure half-time for stenotic mitral valves. In the 1980s, continuous-wave Doppler was validated for measurement of the pressure gradient across stenotic aortic valves, and pulsed-wave Doppler combined with two-dimensional echocardiographic imaging was validated for noninvasive measurement of stroke volume and cardiac output...

BACKGROUND: Accurate fetal arrhythmia (FA) diagnosis is key for effective management. Currently, FA assessment relies on standard echocardiography-based techniques (M mode and spectral Doppler), which require adequate fetal position and cursor alignment to define temporal relationships of mechanical events. Few data exist on the application of color Doppler tissue imaging (c-DTI) in FA assessment. The aim of this study was to examine the feasibility and clinical applicability of c-DTI in FA assessment in comparison with standard techniques...

BACKGROUND: Heart failure (HF) is known to be the most widespread epidemic of cardiovascular disease. Among several factors with prognostic value for the clinical course of HF, left atrial (LA) function has not yet been fully examined. The aim of this prospective study was to evaluate LA function for the prediction of major cardiovascular outcomes in stable patients with chronic HF with reduced ejection fraction. Additionally, as secondary end points, cardiovascular mortality and atrial fibrillation were analyzed separately...

BACKGROUND: Three-dimensional (3D) echocardiography with multiplanar reconstruction (MPR) is used clinically to quantify the mitral annulus. MPR images are, however, presented on a two-dimensional screen, calling into question their accuracy. An alternative to MPR is an autostereoscopic holographic display that enables in-depth visualization of 3D echocardiographic data without the need for special glasses. The aim of this study was to validate an autostereoscopic display using sonomicrometry as a gold standard...

BACKGROUND: Pulmonary insufficiency (PI) and right ventricular (RV) dysfunction are long-term complications in patients with repaired tetralogy of Fallot (rTOF). The aim of this study was to investigate RV contractile reserve and changes in PI that occur during exercise in patients with rTOF and the associations of these changes with exercise performance using stress echocardiography. METHODS: Subjects with rTOF (n = 32) and healthy control subjects (n = 10) were prospectively enrolled and underwent rest and peak exercise echocardiography during standard cardiopulmonary exercise test protocol on a cycle ergometer or treadmill...

BACKGROUND: Transthoracic echocardiography (TTE) and magnetic resonance imaging (MRI) have yielded excellent results in aortic root diameter measurement in patients with tricuspid aortic valve. However, accuracy in bicuspid aortic valve (BAV), often associated with aortic root asymmetry, is not fully defined. The aim of this study was to determine the agreement between TTE and MRI in proximal ascending aortic diameters in patients with BAVs. METHODS: Seventy-six consecutive patients with BAVs (mean age, 53 ± 15 years; 65% men) who underwent both TTE and MRI for ascending aortic assessment in a follow-up protocol were included in the study...

BACKGROUND: Tricuspid valve imaging is frequently challenging and requires the use of multiple modalities. Knowledge of limitations and methodologic discrepancies among different imaging techniques is crucial for planning transcatheter valve interventions. METHODS: Thirty-eight patients with severe symptomatic tricuspid regurgitation were included in this retrospective analysis. Tricuspid annulus (TA) measurements were made during mid-diastole using three-dimensional (3D) transthoracic echocardiographic direct planimetry (TTE_direct) and transesophageal echocardiographic direct planimetry (TEE_direct)...

BACKGROUND: New three-dimensional echocardiographic automated software (HeartModel) is now available to quantify the left heart chambers. The aims of this study were to assess the feasibility, reproducibility, and analysis time of this technique and its correlation with manual three-dimensional echocardiography (3DE) and cardiac magnetic resonance (CMR) in children. METHODS: Ninety-two children (5-17 years of age) were prospectively included in two separate protocols...
