Semi-automated quantification of left ventricular volumes and ejection fraction by real-time three-dimensional echocardiography

Semi-automated quantification of left ventricular volumes and ejection fraction by real-time three-dimensional echocardiography

BACKGROUND Recent studies have shown that real-time three-dimensional (3D) echocardiography (RT3DE) gives more accurate and reproducible left ventricular (LV) volume and ejection fraction (EF) measurements than traditional two-dimensional methods. A new semi-automated tool (4DLVQ) for volume measurements in RT3DE has been developed. We sought to evaluate the accuracy and repeatability of this m...

Left ventricular ejection fraction by real-time three-dimensional echocardiography

Despite a staggering technical progress in echocardiography, in daily clinical practice assessment of left ventricular (LV) ejection fraction (EF) is still often done in a rather inaccurate two-dimensional (2D) manner. Real-time three-dimensional echocardiography (RT3DE) provides a more representative realistic view of LV volumes, thereby being the Necker cube for the naive realism of 2D method...

Left ventricular volumes and ejection fraction by echocardiography.

Evaluation of left atrial volumes and ejection force by real-time three-dimensional echocardiography.

We read with great interest the article by Zhong et al1 entitled ‘Effects of age and gender on left atrial ejection force and volume from real-time three-dimensional echocardiography’. The authors determined the normal reference values for left atrial (LA) volumes and LA ejection force (LAEF) assessed by real-time three-dimensional echocardiography (RT3DE). The study was interesting, but we hav...

Left Ventricular Volumes and Ejection Fraction

Left ventricular end-diastolic and end-systolic volume, stroke volume, and ejection fraction were determined by biplane angiocardiography and echocardiography in 27 patients suspected of having heart disease. Angiographic volumes were calculated by the area-length method and echocardiographic volumes, from the left ventricular dimension of the echograms. The angiographic minor diameter and the ...
