The Amplatzer atrial defect occluder was used to close the ASD<\/jats:styled-content>s. Transthoracic echocardiographic examinations were performed at 3 points in time: the day before closure, 1\u00a0day after closure, and 3\u00a0months after closure. The dimensions of the right atrium (RA<\/jats:styled-content>) and the right ventricle (RV<\/jats:styled-content>) were measured in apical four\u2010chamber view. RV<\/jats:styled-content> segmental longitudinal systolic strains (SLS<\/jats:styled-content>s) and global longitudinal systolic strain (GLS<\/jats:styled-content>) were obtained by two\u2010dimensional STE<\/jats:styled-content>.<\/jats:p><\/jats:sec>Results<\/jats:title>Before ASD<\/jats:styled-content> closure, the RV SLS<\/jats:styled-content>s and GLS<\/jats:styled-content> were significantly higher than those of the controls. At 1\u00a0day after closure, the diameters of RA<\/jats:styled-content> and RV<\/jats:styled-content> decreased. All the RV SLS<\/jats:styled-content>s and GLS<\/jats:styled-content> decreased accordingly and were lower than the control values. At 3\u00a0months after closure, the apical free wall strain, all segments of septal strains, and GLS<\/jats:styled-content> increased significantly compared with the values obtained at 1\u00a0day after closure. The diameters of the RA<\/jats:styled-content> and RV<\/jats:styled-content> decreased further as well. There were no significant differences in the strains compared with the control values, except for the free wall basal strain.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Transcatheter device closure
