Automated Left Ventricular Function Evaluation by LVivoEF

• Conditions: EF Evaluation From 4 Chamber Plane; EF Evaluation From 2 Chamber Plane; Biplane EF Evaluation; Left Ventricular Function

• Registration Number: NCT01515267
• Lead Sponsor: DiA Imaging Analysis Ltd

Brief Summary

Left ventricular ejection fraction (EF) is evaluated in every echocardiographic examination either by visual estimation (eyeballing) requiring high level of training and expertise and/or by manual tracing of the endocard from which EF is calculated (manual biplane method (MBP)). This procedure is subjective and time consuming. The objective of this study is to compare the performance of LVivoEF software system to the measurements obtained by the routinely used methods.

Detailed Description

LVivoEF is a decision support system (software) for automated global left ventricle (LV) systolic function evaluation from echocardiographic examinations. LVivoEF technology is based on a novel image processing algorithm for LV edge detection and ejection fraction (EF) evaluation. LVivoEF provides fully automated measurements of the left ventricle (LV) from two apical views the four chamber (4CH) and the two chamber (2CH).
