In the 16th century, Leonardo DaVinci already described the rotational motion of the left ventricle (LV)1,2 and in 1669, Richard Lower observed that myocardial contraction could be compared with the wringing of a linen cloth to squeeze out the water.3 Three centuries later, the use of radiopaque markers in cineradiographic studies made it possible to measure this wringing motion in the human heart, as was shown by Ian McDonald and Neil Ingels.4,5 The mechanistic basis for this wringing motion or twist lies in the complex spiral architecture of the LV as revealed by the anatomical studies of
