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.

||Automated Left Ventricular Function Evaluation by LVivoEF
| Estimated Enrollment:
| Study Start Date:
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).
|Ages Eligible for Study:
||18 Years and older
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
patients referred to an echocardiographic examination
- Age > 18
- Patients referred to an echocardiographic examination. The patients will be consecutive until 30% of patients with normal LV function are enrolled. After that only consecutive patients with abnormal LV function will be included.
- Examinations in which more than one third of the endocard is not visible in a plane (2CH/4CH)
- Patients with Left bundle branch block (LBBB)
