Late Electrical and Mechanical Remodeling After Atrial Septal Defect Closure in Children: Surgical Versus Percutaneous Approach

Either surgical or percutaneous closure of atrial septal defect have a similar efficacy on the volume normalization of the right chamber. Modern surgical techniques have a limited impact on the systolic and diastolic function as well as on the arrhythmic risk; however, the right ventricular longitudinal and diastolic function seems to be better preserved in the percutaneous group.
