Why the study?
Does speckle-tracking echocardiography reveal differences in left ventricular torsion between children with hypertrophic cardiomyopathy, concentric hypertrophy, and healthy controls?

Children with hypertrophic cardiomyopathy exhibit increased left ventricular torsion driven by enhanced systolic basal clockwise rotation, distinguishing their mechanics from those with concentric hypertrophy.
No takes yet. Share an insight, caveat, or question.
Increased torsion may distinguish pediatric HCM mechanics; leaves open its prognostic or therapeutic role.
Prinz et al. (2013) studied this question.
