Ultrasound Methods of Myocardium Strain Evaluation and Their Clinical Significance. Clinical Significance of Myocardium Strain and Rotation Measurements

M.N. Alekhin

Clinical value of left ventricle myocardium strain and torsion measurements is described in the lecture. Changes of left ventricle myocardium strain and torsion data at some physiological and different pathologic situations as a ventricle hypertrophy, heart failure, myocardial infarction, congenital heart disease, and cardiomyopathy are represented. Differential diagnosis questions of the left ventricle hypertrophy reasons with the myocardium strain measurements use are discussed. Prognostic value of left ventricle myocardium strain and torsion measurements is showed.

Keywords:
echocardiography, myocardium strain, strain rate, speckle tracking, longitudinal strain, circumferential strain, radial strain, torsion (twist), and tissue Doppler imaging.
