Conditions ef evaluation from 4 chamber plane, ef evaluation from 2 chamber plane, biplane ef evaluation, left ventricular function
Sponsor Diacardio LTD
Start date November 2011
Trial size 100 participants
Trial identifier NCT01515267, DIA100


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.

Eligibility Criteria

Male or female participants at least 18 years old.

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)

Additional Information

Official title Automated Left Ventricular Function Evaluation by LVivoEF
Principal investigator Noah Liel-Cohen, MD
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).
