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.

Estimated Enrollment: 100
Study Start Date: November 2011
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).

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
patients referred to an echocardiographic examination

Inclusion Criteria:

  • 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.

Exclusion Criteria:

  • 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)
