Intermediate Outcome of Transcatheter Closure of Secundum Atrial Septal Defect on Cardiac Remodeling in Egyptian Children and Adults

Background: Atrial septal defects (ASDs) are the second most common congenital lesion in adults. ASD closure is followed by symptomatic improvement and regression of pulmonary artery pressure (PAP), reduction in right heart volume overload and hence the prevalence of arrhythmias, thus quantification of the RV function is an important prognostic factor. Tissue Doppler and strain imaging are helpful tools for the assessment of RV systolic and diastolic function.
