BACKGROUND: Recently, a new automated software package (HeartModel) was developed to obtain three-dimensional (3D) left ventricular (LV) volumes using a model-based algorithm (MBA) with a "one-button" simple system and user-adjustable slider. The aims of this study were to verify the feasibility and accuracy of the MBA in comparison with other commonly used imaging techniques in a large unselected population, to evaluate possible accuracy improvements of free operator border adjustments or changes of the slider's default position, and to identify differences in method accuracy related to specific pathologies...

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...

BACKGROUND: The 2015 American Society of Echocardiography/European Association of Cardiovascular Imaging recommendations for chamber quantification suggest new abnormality threshold and severity partition values for left atrial (LA) volume that are equally valid for the biplane method of disk (MOD) summation and the area-length method (ALM). However, they have never been clinically validated. Thus, we compared the clinical and prognostic impact of LA volume assessed by MOD and ALM by using both the 2015 and 2005 abnormality thresholds...

BACKGROUND: Chemotherapy-induced cardiotoxicity has not been extensively validated in bone marrow transplantation (BMT) patients. Speckle-tracking echocardiography is a sensitive method for the detection of subclinical cardiac dysfunction. METHODS: Cardiac function was prospectively assessed in 80 patients (44 men; mean age, 45 ± 11 years) after BMT for non-Hodgkin's lymphoma and acute or chronic myeloid leukemia by means of various echocardiographic techniques...

BACKGROUND: Early detection of right ventricular (RV) failure is required to improve the management of patients with congenital heart diseases. The aim of this study was to validate echocardiography for the early detection of overloaded RV dysfunction, compared with hemodynamic and myocyte contractility assessment. METHODS: Using a porcine model reproducing repaired tetralogy of Fallot, RV function was evaluated over 4 months using standard echocardiography and speckle-tracking compared with hemodynamic parameters (conductance catheter)...

BACKGROUND: Epicardial adipose tissue (EAT) is the ectopic visceral fat surrounding the heart, which plays an important role in atherosclerosis of the coronary arteries via endothelial damage. Several studies have also suggested that vasospasm with angina (VSA) causes endothelial dysfunction in the coronary arteries. The aim of this study was to evaluate the thickness of EAT in the anterior interventricular groove (EAT-AIG) using echocardiography in patients who had no obstructive coronary artery disease and were suspected of having VSA...

Isolated reoperative tricuspid valve replacement is one of the highest risk operations classified in the Society of Thoracic Surgeons registry, particularly in the setting of preexisting right ventricular dysfunction. Transcatheter tricuspid valve-in-valve implantation represents an attractive alternative to redo surgery in patients with tricuspid bioprosthetic valve degeneration who are considered high-risk or unsuitable surgical candidates. In this review article, the authors discuss the emergence of transcatheter tricuspid valve-in-valve therapy, preprocedural echocardiographic assessment of tricuspid bioprosthetic valve dysfunction, periprocedural imaging required for tricuspid valve-in-valve implantation, and postprocedural assessment of tricuspid transcatheter device function...

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...

BACKGROUND: Left ventricular (LV) filling following atrial contraction generates LV myocardial stretch that propagates from base to apex with a speed proportional to myocardial elasticity. The aim of this study was to test the hypothesis that intrinsic velocity propagation of myocardial stretch (iVP) would be altered in patients with valvular disease and chronic LV pressure overload or volume overload, which may adversely affect mechanical properties of the LV tissue. A second aim was to compare iVP with flow propagation velocity in the chamber...

BACKGROUND: Detecting bioprosthetic mitral valve dysfunction on transthoracic echocardiography can be challenging because of acoustic shadowing of regurgitant jets and a wide normal range of transvalvular gradients. Several studies in mechanical mitral valves have demonstrated the utility of the transthoracically derived parameters E (peak early mitral inflow velocity), pressure half-time, and the ratio of mitral inflow velocity-time integral (VTIMV) to left ventricular outflow tract velocity-time integral (VTILVOT) in detecting significant prosthetic dysfunction...

BACKGROUND: Cardiotoxicity is a well-known adverse effect of various chemotherapeutic agents that can be monitored by echocardiography. A decrease in left ventricular ejection fraction (LVEF) triggers consideration for therapy modification or interruption. The aim of this study was to evaluate how variability in LVEF estimates computed using three-dimensional echocardiography could influence cardiotoxicity onset detection. METHODS: One hundred eighty one patients with breast cancer treated with anthracycline and trastuzumab were analyzed...

BACKGROUND: Flail mitral leaflet is a common complication of degenerative mitral regurgitation (MR) and is generally equated with severe MR. However, a flail mitral leaflet is not always associated with severe MR. The hemodynamic and clinical significance of a flail leaflet in the absence of severe MR has not been characterized. The authors identified cases of flail mitral leaflet associated with only mild or moderate MR and evaluated their echocardiographic features and clinical outcomes...

BACKGROUND: Vector flow mapping (VFM) enables direct visualization of flow pattern and estimation of flow volume. The aim of this study was to determine its accuracy in the quantification of pulmonary regurgitation (PR) in congenital heart patients after repair of right ventricular (RV) outflow obstruction. METHODS: This study comprised two parts: (1) validation of VFM in the quantification of PR in patients with repaired tetralogy of Fallot by cardiac magnetic resonance and (2) clinical application of VFM to determine PR in patients after biventricular repair of pulmonary atresia and stenosis with intact ventricular septum...

Despite the already well-known role the right side of the heart plays in many diseases, right ventricular (RV) function has only recently been carefully considered. Echocardiography is the first-line diagnostic technique for the assessment of the right ventricle and right atrium, whereas cardiac magnetic resonance is considered the gold standard but is limited by cost and availability. According to the current guidelines, systolic RV function should be assessed by several conventional measurements, but the efficacy of these parameters as diagnostic and prognostic tools has been questioned by many authors...
