Speckle tracking echocardiography: principles and clinical applications

Speckle Tracking Echocardiography is a relatively new, non-invasive ultrasound technique that allows an objective and quantitative evaluation of global regional myocardial function. There lot evidence longitudinal strain more sensitive than the left ventricular ejection fraction for assessment dysfunction, used to follow-up cancer therapeutic-related cardiac stratify risks, classify determine treatment in asymptomatic dysfunction. Thus, this can help identify function subclinical even when normal. Currently, speckle tracking echocardiography has been standardized applied evaluate function, right atrial according consensus American Society European Association Cardiovascular Imaging.
