Key result
Extraction of hemodynamic information from echocardiograms using kinetic energy fluxes and pressure stresses allows for the development of novel cardiac indices for clinical evaluation.
The study proposes novel echocardiographic indices based on kinetic energy fluxes and ventricular work to complement traditional measures like LVEF and stroke volume.
May complement LVEF with novel echocardiographic indices; leaves open prospective validation before clinical use.
This study extracted hemodynamic information from echocardiogram to complement the left ventricle ejection fraction and the stroke volume for cardiac evaluation and diagnosis. The dynamic characteristics of irregular wall motions can be analyzed by kinetic energy fluxes transferred from the left ventricle to the blood flow. A set of cardiac indices is developed for quantification and classification of echocardiogram for clinical application. The pumping characteristics can be further quantified through the work done by pressure and viscous stresses of the ventricle.
