Key result
Dipyridamole stress induced near absence of left ventricular twist, known as rigid body rotation, in a patient with significant coronary artery disease.
Why the study?
The study was designed to present a case of near absence of LV twist, termed LV rigid body rotation, induced during dipyridamole stress in a patient with significant coronary artery disease.

Dipyridamole stress can induce left ventricular rigid body rotation in patients with significant coronary artery disease, detectable by 3D speckle-tracking echocardiography.
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.

Nemes et al. (2019) conducted a case report in Coronary artery disease (n=1). Dipyridamole vs. Baseline was evaluated on Left ventricular rotational mechanics (LV twist/rigid body rotation). Dipyridamole stress induced near absence of left ventricular twist, known as rigid body rotation, in a patient with significant coronary artery disease.
