摘要

•Rotational mechanics in children with noncompaction cardiomyopathy were studied.•RAR in the clockwise direction occurred in 40% of children.•Left ventricular dysfunction, heart failure, and arrhythmias were associated with RAR.•Patients with premature untwisting during ejection had decreased ejection fraction.•RAR is possibly related to dysfunction of the apical compacted layer of myocardium.
