The immediate haemodynamic response and right and left cardiac remodelling after percutaneous transcatheter closure of secundum atrial septal defect in children: a longitudinal cohort study.

This study with a very high interventional success rate can be counted as the first example of research on the haemodynamic response and timing of cardiac remodelling after PTC of secundum ASD in children. We suggest that future multicentric studies with larger cohorts and a comprehensive methodology like ours with longer follow-up periods would better serve to further assess the cardiac remodelling in children after PTC of secundum ASD.
