Article Title: 3D echocardiographic global longitudinal strain can identify patients with mildly-to-moderately reduced ejection fraction at higher cardiovascular risk.
Article Snippet: Severely reduced left ventricular (LV) ejection fraction (EF) derived from 2D echocardiographic (2DE) images is associated with increased mortality and used to guide therapeutic choices.. Global longitudinal strain (GLS) is more sensitive than LVEF to detect abnormal LV function, and accordingly may help identify patients with mildly-to-moderately reduced LVEF who are at a similarly high cardiovascular (CV) risk.. We hypothesized that 3D echocardiographic (3DE) measurements of EF and GLS, which are more reliable and reproducible, may have even better predictive value than the 2DE indices, and compared their ability to identify such patients.

Article Title: Tricuspid annular dilation in patients undergoing early mitral valve surgery: is it an old story?
Article Snippet: Patients with mitral valve prolapse (MVP), undergoing early surgery for severe regurgitation, are usually characterized by a low degree of right chambers’ remodeling.. In this selected population, the mechanisms leading to tricuspid annular (TA) dilatation (TAD) are not well understood.. In this setting, we aimed to evaluate, using three-dimensional echocardiography (3DE), how right chambers affect TA size and might contribute to functional tricuspid regurgitation (FTR) progression.

Article Title: Whole blood transcriptome characterization of young female triathlon athletes following an endurance exercise: a pilot study.
Article Snippet: 3DE data sets of the RV and LV were analyzed offline to measure the end-diastolic and end-systolic volumes [indexed it on body surface area: end-diastolic volume index (EDVi), end-systolic volume index (ESVi)], and the ejection fraction (EF) of the right and left ventricle using a commercial software package (4D LV-Function 3, 4D RV-Function 2, TomTec Imaging Systems GmbH, Unterschleissheim, Germany).

Article Title: Normal Values of Cardiac Output and Stroke Volume According to Measurement Technique, Age, Sex, and Ethnicity: Results of the World Alliance of Societies of Echocardiography Study.
Article Snippet: Background: Assessment of cardiac output (CO) and stroke volume (SV) is essential to understand cardiac function and hemodynamics.. These parameters can be examined by three echocardiographic techniques (pulsed wave Doppler, 2D and 3D).. Whether these methods can be used interchangeably is unclear.

Article Title: 3D Morphological Changes in LV and RV During LVAD Ramp Studies.
Article Snippet: 3D TTE images were analyzed using commercial software (4D LV-Function and 4D RV-Function, version 2.0, TomTec Imaging Systems, Unterschleissheim, Germany) to quantify end-diastolic and end-systolic volumes and ejection fraction of both ventricles.
