Abstract:

Introduction: Any opening between the two atria other than a competent foramen ovale is an interatrial defect, which accounts for 6%–10% of all CHD in children, with a 2:1 female preponderance. Transcatheter secundum ASD closure is adopted worldwide. 
Aim of the study: To measure right atrial (RA) and right ventricular (RV) size and quick remodeling to normal in children after percutaneous secundum atrial septal defect repair using the Amplatzer septal occluder. 
Methods: The research included 70 children aged 4-14.5 years (7.61±2.5 years). Using 2D TTE, longitudinal, transverse axis, area of RA, RV inflow dimensions at basal one-third and midway between the tricuspid annulus and the apex, short axis, and M-mode RV at end diastolic dimensions were measured (indexed to body surface area). Measurements were taken before, 24 h, 1 month, and 3 months after the procedure and compared to the control group. 
Results: A substantial difference (p<0.05) was seen in all measures between patients and controls. A substantial positive link between RAD1, RAD2, RAA, RVD1, RVD2, RVD3, RVD4, and RVD5 with time. Right ventricular transverse dimension (RVD1 and RVD2), RA transverse axis (RAD2), and longitudinal axis dimensions (RAD1 and RVD3) normalized after 3 months, although RAA, RV short axis, and M-mode RV end diastolic dimension decreased slowly. The transverse-to-longitudinal RA axis ratio increased considerably after 3 months of ASDII. 
Conclusions: Right atrial and right ventricular measures drop fast in the first 24 hours and usually normalise within 3 months. M-mode and short axis RV end diastolic and RAA end systolic dimensions don't show RV alterations. The greater transverse to longitudinal RA axis ratio indicates that Amplatzer septal occluder closure of ASD affects RA geometry.
