This study sought to investigate regional left ventricular (LV) rotation in patients with hypertrophic cardiomyopathy (HCM). The study comprised 44 patients with HCM with a typical reverse septal curvature (age 40 14 years, 33 men) and 44 healthy volunteers (age 39 14 years, 32 men) in whom LV rotation could be assessed at the basal and apical LV level with speckle-tracking echocardiography, using the QLAB Advanced Quantification Software version 6.0 (Philips, Best, The Netherlands). In HCM patients, lower values of initial counter-clockwise rotation at the basal LV level (1.5 1.2 vs. 0.6 0.9, P 0.001) were seen, in p Changes in rotation and back-rotation at the LV basal level in HCM patients are mainly caused by regional changes in the basal septal and anterior segments, the segments mostly involved in the hypertrophic process.
