Change of left ventricular “rigid body rotation” during dipyridamole-induced vasodilation: A case from the three-dimensional speckle tracking echocardiographic MAGYAR-Stress Study

A patient with previous coronary stenting presented with stable angina and positive exercise treadmill test. Echocardiography with three-dimensional speckle-tracking demonstrated left ventricular rigid body rotation (near absence of left ventricular twist), whose characteristics changed dramatically during dipyridamole-induced vasodilatation. © 2017 Wiley Periodicals, Inc.
