Introduction: ASD closure causes electrical and mechanical reverse remodelling after shunt closure. There haven’t been many studies to determine whether surgical closure or device closure is better for regressing right heart volumes. In comparison to secundum ASD closure, transcatheter ASD closure has shown to be more affordable while eliminating the common risks of surgical closure, such as cardiac trauma and wound problems. Aim and Objective: To assess right heart function, right atrial and right ventricular dimensions pre and post transcatheter closure of atrial septal defect (ASD). Materials and Methods: From August 2021 to December 2022, 50 research participants participated in this descriptive longitudinal study at the LPS Institute of Cardiology in Kanpur, Uttar Pradesh. All ostium secundum ASD patients who were referred for closure were examined. Patients of both sexes are chosen for the investigation. For each patient, pertinent history, a clinical examination, pulse oximetry, a chest X-ray, and an ECG were performed. Each patient had a thorough transthoracic and transoesophageal echocardiogram performed. Results: At immediate post-closure, one week, and three months after closure, the mean RV longitudinal measurement was 6.31 cm, 6.07 cm, and 5.96 cm, respectively. F=359.324, P < 0.001, indicates that there is a significant difference between the 4 occurrences. Further numerous comparisons of the occasions reveal that every pair differs considerably. The mean MPI was 4.173, however, it fell to 3.93, 3.592, and 3.199 at the immediate, 1-week, and 3-month post-closure times. Further numerous comparisons of the occasions reveal that every pair differs considerably. F=444.425, P< 0.001 indicates that there is a significant difference between the 4 occurrences. Conclusions: Comparable positive effects are shown on hemodynamics, right heart dimensions, and functional capacity. Immediately upon device closure, the highest favourable effects on right cardiac functions, remodelling, of heart functions and the advantage is still there three months later.
