BACKGROUND: Children with single-right ventricle anomalies such as hypoplastic left heart syndrome (HLHS) have left ventricles of variable size and function. The impact of the left ventricle on the performance of the right ventricle and on survival remains unclear. The aim of this study was to identify whether left ventricular (LV) size and function influence right ventricular (RV) function and clinical outcome after staged palliation for single-right ventricle anomalies. METHODS: In the Single Ventricle Reconstruction trial, echocardiography-derived measures of LV size and function were compared with measures of RV systolic and diastolic function, tricuspid regurgitation, and outcomes (death and/or heart transplantation) at baseline (preoperatively), early after Norwood palliation, before stage 2 palliation, and at 14 months of age...

Two-dimensional (2D) transthoracic echocardiography is one of the most used diagnostic tools in clinical cardiology. Similarly, 2D transesophageal echocardiography is considered an indispensable tool for cardiologists and cardiac anesthesiologists worldwide. However, because of their tomographic nature, both techniques display only thin cut planes of a given area of the heart, which are far from representing the "anatomic reality." It is widely accepted that experienced echocardiographers are able to reconstruct mentally a three-dimensional image of any cardiac structure on the basis of their interpretation of multiple tomographic slices...

BACKGROUND: The analysis of right ventriculo-arterial coupling (RVAC) from pressure-volume loops is not routinely performed. RVAC may be approached by the combination of right heart catheterization (RHC) pressure data and cardiac magnetic resonance (CMR)-derived right ventricular (RV) volumetric data. RV pressure and volume measurements by Doppler and three-dimensional echocardiography (3DE) allows another way to approach RVAC. METHODS: Ninety patients suspected of having pulmonary hypertension underwent RHC, 3DE, and CMR (RHC mean pulmonary artery pressure [mPAP] 37...

BACKGROUND: Radiation reduction is desirable in children undergoing cardiac catheterization. Three-dimensional (3D) transesophageal echocardiographic (3D TEE) imaging obviates the need for mental reconstruction of 3D structures from two-dimensional images. Three-dimensional TEE imaging is used in atrial septal defect (ASD) closures. Three-dimensional TEE guidance of right heart catheterization (RHC) without fluoroscopy for ASD closures has not been demonstrated. The aim of this study was to evaluate the feasibility of 3D TEE guidance of RHC in ASD closures and radiation reduction compared with historical control subjects...

The use of bioprosthetic valves for mitral valve disease has been increasingly popular with both patients and physicians, and current practice uses these valves for increasingly younger patients. However, these valves are known to degenerate over time. Historically, reoperation was the only recourse for a failing bioprosthetic valve. Today, however, percutaneous options exist with the use of transcatheter valve implantation. Determining candidacy for this less invasive option requires careful evaluation with echocardiography...

BACKGROUND: In prior work, the authors demonstrated that two-dimensional speckle-tracking (2DST) correlated well but systematically overestimated global longitudinal strain (LS) and circumferential strain (CS) compared with two-dimensional cardiac magnetic resonance tagging (2DTagg) and had poor agreement on a segmental basis. Because three-dimensional speckle-tracking (3DST) has recently emerged as a new, more comprehensive evaluation of myocardial deformation, this study was undertaken to evaluate whether it would compare more favorably with 2DTagg than 2DST...

BACKGROUND: The American Society of Echocardiography (ASE) guidelines suggest the use of several echocardiographic methods to assess mitral regurgitation severity using an integrated approach, without guidance as to the weighting of each parameter. The purpose of this multicenter prospective study was to evaluate the recommended echocardiographic parameters against a reference modality and develop and validate a weighting for each echocardiographic measure of mitral regurgitation severity...

BACKGROUND: Functional assessment of the right ventricle using real-time three-dimensional echocardiography (RT3DE) has fundamental relevance in young patients with congenital heart disease. Reference values for the pediatric population are scarce. This multicenter study was designed to (1) validate new evaluation software for RT3DE and (2) establish pediatric reference values. METHODS: For validation, right ventricular (RV) end-diastolic volume (EDV) and end-systolic volume (ESV) were determined from real-time three-dimensional echocardiographic data sets of 38 subjects (n = 17 healthy individuals and n = 21 patients with congenital heart disease) using new dedicated evaluation software (RV-Function 2...

BACKGROUND: The inferior vena cava (IVC) has a complex three-dimensional (3D) shape, but measurements used to estimate central venous pressure (CVP) remain based on two-dimensional (2D) echocardiographic imaging. The aim of this study was to investigate the accuracy of IVC size and collapsibility index obtained by 3D echocardiography for assessing CVP in patients with cardiogenic shock. METHODS: Eighty consecutive echocardiographic examinations performed in 33 patients (mean age, 72 ± 15 years; mean left ventricular ejection fraction, 19 ± 10%) admitted for cardiogenic shock were prospectively included...

BACKGROUND: Single-photon emission computed tomography (SPECT) is a well-established method to evaluate patients with coronary artery disease. Myocardial contrast echocardiography (MCE) is an imaging technique that allows the assessment of myocardial perfusion in real time. Previous research has shown that vasodilator MCE is superior to SPECT for the prediction of hard events. The aim of this study was to investigate the long-term association of SPECT and MCE with clinical outcomes in patients with known or suspected coronary artery disease...

BACKGROUND: The recently published integrative algorithms for echocardiographic grading of native aortic regurgitation (AR) and mitral regurgitation (MR) by the American Society of Echocardiography are consensus based and have not been evaluated. Thus, the aims of the present study were to investigate the feasibility of individual parameters and to evaluate the ability of the algorithms to discriminate severe from moderate regurgitation. METHODS: This prospective study comprised 93 patients with chronic AR (n = 45) and MR (n = 48)...

BACKGROUND: The aim of this study was to determine whether assessment of left atrial (LA) function helps identify patients at risk for early deterioration during follow-up with mitral valve prolapse and mitral regurgitation. METHODS: Patients with moderate to severe mitral regurgitation but no guideline-based indications for surgery were retrospectively identified from a dedicated clinical database. Maximal and minimal LA volumes were used to derive total LA emptying fraction ([maximal LA volume - minimal LA volume]/maximal L volume × 100%)...

BACKGROUND: The American Society of Echocardiography Committee on Pediatric Echocardiography Laboratory Productivity was formed in 2011 to study institutional factors that could influence the clinical productivity of physicians and sonographers in academic pediatric echocardiography laboratories. In the previous two surveys, staff clinical productivity remained stable while total echocardiography volumes increased. This third survey was designed to assess how clinical productivity is associated with laboratory infrastructure elements such as training, administrative tasks, quality improvement, research, and use of focused cardiac ultrasound (FCU)...
