AIMS: Accurate echocardiographic assessment of left ventricular outflow tract (LVOT) and the aortic root is necessary for risk stratification and choice of appropriate treatment in patients with pathologies of the aortic valve and aortic root. Conventional 2D transthoracic echocardiographic (TTE) assessment is based on the assumption of a circular shaped LVOT and aortic root, although previous studies have indicated a more ellipsoid shape. 3D TTE and multidetector computed tomography (MDCT) applies planimetry and are not dependent on geometrical assumptions...

OBJECTIVES: In daily echocardiographic practice, the right ventricle (RV) is assessed using mostly 2-dimensional (2D) echocardiography. Parameters measuring longitudinal shortening (eg, tricuspid annular plane systolic excursion) or changes in areas (eg, fractional area change) are used as surrogates for right ventricular function. Three-dimensional (3D) echocardiography-based techniques allow for cardiac magnetic resonance imaging-validated assessment of the RV. Depiction of regional right ventricular function is of increasing clinical interest...

Purpose: To evaluate the effect of image quality and contrast enhancement (CE) on left ventricular (LV) volume determination by two- (2D) and three-dimensional (3D) echocardiography (2DE/3DE). Methods: We studied 32 post-myocardial infarction (MI) patients without (2DE/3DE) and with CE (CE2DE/CE3DE), in comparison with cardiac magnetic resonance imaging (CMR). Results: Two-dimensional echocardiography showed the largest negative bias versus CMR for diastolic and systolic volumes (-59, -28 mL, respectively) with lower biases for CE2DE (-37, -22 mL), 3DE (-31, -17 mL), and CE3DE (-17, -11 mL)...

Transcatheter aortic valve replacement (TAVR) is an emerging and a well-established procedure for high-risk and inoperable patients worldwide. Recent studies revealed furthermore that TAVR is equal or even superior to surgical valve replacement in intermediate risk patients. Therefore, a successful procedure is not only dependent on precise preprocedural patient selection but also on careful intraprocedural multimodal imaging guidance and adequate postprocedural follow-up. Up to date, 2D/3D transthoracic and/or transoesophageal echocardiography is an easy and goal-oriented tool for periprocedural TAVR-assessment regarding annulus measurements, cardiac function and concomitant valve diseases...

INTRODUCTION: Variability of blood pressure (BP) has been reported to be related to worse cardiovascular outcomes. We examined the impact of daytime systolic BP variability on left ventricular (LV) function and arterial stiffness in hypertensive patients. METHODS: Ambulatory BP monitoring (ABPM) and echocardiography were performed in 116 hypertensive patients. We assessed BP variability as standard deviations of daytime systolic BP on 24-hour ABPM. Conventional echocardiographic parameters, area strain and 3D diastolic index (3D-DI) using 3D speckle tracking were measured...

Right ventricular (RV) function has proven to be a prognostic factor in heart failure with reduced and preserved ejection fraction and in pulmonary hypertension. RV function is also a cornerstone in the management of novel clinical issues, such as mechanical circulatory support devices or grown-up congenital heart disease patients. Despite the notable amount of circumferentially oriented myofibers in the subepicardial layer of the RV myocardium, the non-longitudinal motion directions are often neglected in the everyday assessment of RV function by echocardiography...

Tricuspid regurgitation (TR) is an independent predictor of death. Lately, emerging technologies for the treatment of TR have increased the interest of physicians. Due to the complex 3-dimensional (3D) geometry of the tricuspid valve (TV) and its anterior position in the mediastinum, conventional 2D echocardiography is unsuitable to study the anatomy and pathophysiologic mechanisms of the regurgitant TV. 3D echocardiography has emerged as a very cost-effective imaging modality with which to: 1) visualize the TV anatomy; 2) define the mechanism of TR; 3) measure the size and geometry of the tricuspid annulus; 4) analyze the anatomic relationships between TV apparatus and surrounding cardiac structures; 5) assess volumes and function of the right atrium and ventricle; and 6) plan surgical repair or guide and monitor transcatheter interventional procedures...

OBJECTIVES: The authors sought to define the feasibility and performance of 3-dimensional (3D) vena contracta area (VCA) measurement in evaluating total residual mitral regurgitation (MR) following percutaneous edge-to-edge (E-EC) mitral valve repair. BACKGROUND: Residual MR severity after percutaneous repair is not only a determinant of procedural success, but also a major prognostic factor. To date, no single echocardiographic method has been recommended for post-procedural MR quantification, with the evaluation currently relying on a complex, multiparametric appraisal...

Patent ductus arteriosus (PDA) occlusion is one of the more common cardiovascular procedures performed in dogs. Two-dimensional imaging has been the primary method of visualizing the PDA and is the basis of its morphologic description. Transesophageal echocardiographic imaging has further characterized the three-dimensional (3D) variation in ductal morphology and shape (circle, oval). An accurate assessment of the shape and dimensions of a PDA in an individual dog is important when making decisions about definitive closure...

BACKGROUND: Multi-detector gated cardiac computed tomography (CCT) allows three-dimensional (3D) quantification of cardiac chambers and is clinically indicated to assess left ventricular assist device (LVAD) malfunction and complications. Automated volumetric analysis is, however, disrupted by inflow cannula artifact in patients with LVAD. With this study, we evaluated intra-observer variability in semi-automated 3D cardiac volumetric analysis using CCT in patients with LVADs. METHODS: Ten clinically indicated CCTs were studied retrospectively from 9 patients with LVADs...
