Left ventricular rotational deformation changes by speckle tracking imaging before and 24 hours after transcatheter closure of large secundum atrial septal defects in children.

Background: Large atrial septal defects (ASDs) in children cause increased volume overload of the right side of the heart which in turn lead to impairment of left ventricular (LV) performance.

Aim: The aim of this study was to evaluate immediate LV rotational deformation changes in children with large ASDs post-device closure and removal of right ventricle (RV) volume overload.

Patients And Methods: Twenty children who underwent transcatheter closure (TCC) of large secundum ASDs were included in the study.
