Comparative Study[Left ventricular volume and ejection fraction by the axius auto ejection fraction method: comparison with manual trace method and visual assessment of ejection fraction].
Visual assessment of the ejection fraction (EF) is often used in clinical practice, but is subjective and requires training and experience. The auto EF method has been newly developed for automated detection of the left ventricular (LV) endocardial border throughout the cardiac cycle. The clinical feasibility was assessed of the auto EF method for measuring LV volumes and EF in patients. Manually traced EF measured by the biplane modified Simpson's rule was used as the reference standard. ⋯ The auto EF method is a clinically useful tool for the measurement of LV volumes and EF.
