Under normal physiological conditions, the direction of systolic rotation of the left ventricular (LV) base is clockwise, and that of the LV apex is counterclockwise resulting in the wringing motion of the LV around its long axis called as LV twist. The present study was designed to present a patient with significant coronary artery disease in whom near absence of LV twist called as LV rigid body rotation could be induced during dipyridamole stress as assessed noninvasively by three-dimensional speckle-tracking echocardiography.
