Key result
Left ventricular 'rigid body rotation' is a rare phenomenon characterized by the near absence of left ventricular twist, found with higher prevalence in certain cardiac disorders like noncompaction cardiomyopathy.
Why the study?
Left ventricular rigid body rotation is a rare and not fully understood entity characterized by LV apex and base moving in the same direction during ejection.
Left ventricular rigid body rotation, assessed via 3D speckle-tracking echocardiography, is a distinct mechanical abnormality present in specific cardiomyopathies and systemic diseases, highlighting its potential diagnostic value.
LV rigid body rotation remains poorly characterized; leaves open mechanistic and prognostic questions for future study.
Left ventricular (LV) twist is defined as the wringing motion of the LV around its long-axis during systole generated by rotation of the LV apex in a counterclockwise direction, as viewed from the apex, while the LV base moves in a clockwise direction. In several cases, the LV apex and base move in the same direction during ejection demonstrating a special condition called as LV 'rigid body rotation'. The present review aimed to summarize our knowledge about this rare but not fully understood entity demonstrating its theoretic pathophysiologic background, clinical significance, associated diseases, and reversibility based on available literature.

Nemes et al. (2022) conducted a review in Left ventricular 'rigid body rotation' (LV-RBR). Left ventricular 'rigid body rotation' was evaluated. Left ventricular 'rigid body rotation' is a rare phenomenon characterized by the near absence of left ventricular twist, found with higher prevalence in certain cardiac disorders like noncompaction cardiomyopathy.
