BACKGROUND Strain and strain rate have been proposed as tools to quantify regional myocardial function. One of the major pitfalls of the current methodology is its angle dependency. To overcome this problem, we have developed a new method for the estimation of strain, independent of angle. The aim of this study was to validate this new methodology in an experimental setting using sonomicrometry. METHODS AND RESULTS In 5 open-chest sheep, ultrasound data were acquired. The new methodology was… CONTINUE READING
