Correlations between echocardiographic aortic elastic properties and left ventricular rotation and twist--insights from the three-dimensional speckle-tracking echocardiographic MAGYAR-Healthy Study.

Abstract

There is an interaction between the left ventricle (LV) and the vascular system, which plays a crucial role in determining cardiac output. LV twist could be evaluated by three-dimensional speckle-tracking echocardiography (3DSTE) as the net difference of counterclockwise apical and clockwise basal LV rotations during systole. Aortic elasticity parameters could be measured during a routine transthoracic echocardiographic examination. The current study was designed to evaluate correlations between echocardiographic aortic elastic properties and LV rotational mechanics in healthy subjects.
