Accurate noninvasive assessment of LV diastolic dysfunction is highly desirable, and the relationship between the degree of LVEDP and LV torsion dynamics assessed by 2D speckle tracking is not clearly assessed; here in our study we aimed to assess the relation between the degree of LVEDP and torsion dynamics of left ventricle. Methods: The study included sixty patients divided equally into 3 groups according to the degree of LVEDP, group I: <12mmHg, group II: 12 - 18 mmHg, and group III: >18 mmHg; complete conventional echo-Doppler study includes also annular septal E wave peak velocity, E/EĄŻ ratio and 2D-speckle tracking including parameters of LV global longitudinal strain (GLS), peak and time to peak of twist ratio (TR & TT respectively), peak and time to peak of untwist ratio (UTR &
