Background Accurate assessment of the right ventricle is increasingly important. Measures of right ventricular (RV) systolic function, including fractional area change, tissue Doppler (s′ velocity), and tricuspid annular plane systolic…
Background Chronic mitral regurgitation (MR) often leads to diminished right ventricular (RV) function due to long-standing pressure and volume overload. Surgical intervention often adds to the preexisting RV dysfunction. Percutaneous…
Background Right ventricular volume quantification using real-time three-dimensional echocardiographic (RT3DE) imaging is limited by technical shortcomings of acquisition and quantification. In this study, a two-step approach was used to overcome…
Background Several methods that estimate right atrial pressure (RAP) from echocardiographic parameters have been proposed. However, their precision (i.e., how much they decrease RAP estimation uncertainty) is unknown. The aim…
Background Left ventricular (LV) twist may be a compensatory mechanism to preserve ejection fraction (EF). In patients with hypertension, twist varies depending on the left ventricle’s degree of remodeling and…
Background Three-dimensional echocardiography (3DE) is a reliable and reproducible tool for assessing left ventricular (LV) function but remains sensitive to patient echogenicity. Contrast-enhanced 3DE (C3DE) has the potential to improve…
Background The response of diastolic Doppler indices to exercise is not well defined for young subjects. The aims of this study were to evaluate this in nonathletic and endurance-trained probands…
Background Subendocardial strain analysis is currently feasible in two-dimensional and three-dimensional (3D) echocardiography; however, there is a lack of clarity regarding the most useful strain component for subclinical disease detection….
In this issue of JASE, Studer Bruengger et al . report diastolic exercise data in young nonathletic and endurance-trained healthy individuals, along with maximal oxygen consumption (V o 2max ). They…
The left ventricle is an amazing structure, capable of ejecting ≥60% of its contents at high pressure, then filling at very low pressure in a fraction of a second. Remarkably,…
