Implication
May facilitate routine LV quantification; leaves open prospective validation against cardiac MRI.
Key Points
- To review real-time three-dimensional echocardiographic image acquisition and quantitative methods for assessing left ventricular function and myocardial mass.
- Evaluated real-time 3-D echocardiographic acquisition techniques and workflow compared with conventional reconstructed 3-D echocardiography.
- Assessed quantitative analysis approaches for measuring left ventricular volume, ejection fraction, and mass, including in anatomically complex conditions such as left ventricular aneurysms.
- Real-time 3-D echocardiography overcomes the limitations of reconstructed 3-D imaging by removing the need for complex computer systems, respiratory or electrocardiographic gating, and long acquisition times.
- The modality allows rapid visualization of full cardiac geometry and accurate quantification of left ventricular metrics despite image resolution constraints.

Real-time 3-D echocardiography
Real-time 3-D echocardiography provides a fast and convenient alternative to reconstructed 3-D echo for evaluating left ventricular volume, ejection fraction, and mass.
Limitations
- Image quality of the current real-time 3-D echocardiographic methods is not optimal
- image quality of the current real-time 3-D echocardiographic methods is not optimal
Cite This Study
Qin et al. (2000) conducted a review in Left ventricular function and mass evaluation. Real-time 3-D echocardiography was evaluated. Real-time 3-D echocardiography provides a convenient and fast method for visualizing cardiac anatomy and quantifying left ventricular volumes, ejection fraction, and myocardial mass.
