WebPoster session Friday 13 December - PM: 13/12/2013, 14:00-18:00 * Location: Poster area WebThe agreement of measurements between the two methods was also assessed. Pearson’s correlation between the LVEF estimated by the participants and the quantitative LVEF using the modified Simpson method was 0.818 (p < 0.001). Of a total of 245 responses, 120 (49.0%) responses were correct grading of the LV function.

Left ventricular ejection fraction (LVEF) is the critical parameter used heart failure (HF) [].Today, more than 50 years after the first reports describing it [], LVEF likely remains the most used parameter to assess LV systolic performance, because of the simplicity of its calculation by whatever non-invasive imaging method, the ease of …

All studies were evaluated by a single reader (VP).
WebA normal EF ranges from 55-69%, and is calculated using the following equation: Ejection fraction (EF) in percentage is defined as: EF (%) = SV/EDV x 100. Where SV: Stroke Volume and EDV: End Diastolic Volume. Ejection fraction (EF) is basically a percentage, of how much blood the left ventricle pumps out with each contraction.
