Background: Secundum atrial septal defects (ASD2) are one of the most common congenital disorders in children which includes about 10%–20% of congenital heart defects. In recent years, closure of secundum ASD percutaneously has been proposed to reduce mortality, morbidity, and become the standard method in both pediatric and young adults. The aim of this study was to determine the right ventricular (RV) function by strain and strain rate echocardiography parameters in children who underwent surgically versus percutaneous ASD2 device closure. Methods: In this cohort study, all children underwent ASD2 treatment from May 2014 to April 2016 were enrolled in this study. Echocardiography was performed 24 h after transcatheter closure and 3 days after surgical closure. MyLab 60 echo machine (Esoate, Florance, Italy) equipped with a multi-frequency 5 MHz transducer was used, and all echocardiographic data were collected by same pediatric cardiologist. All demographic characteristics and echocardiography indices were compared using SPSS version 18 between two groups. Results: Thirty-six patients (63.2%) were treated by the transcatheter closure and 21 (36.8%) underwent surgery. Longitudinal RV strain (S), longitudinal RV strain rate (S'), and early diastolic longitudinal RV strain rate (E') were improved significantly in device patients in comparison with surgical patients (P < 0.001). There were no significant differences between RV longitudinal dimension and Mid RV size change after procedures in two groups (P > 0.05). However, tricuspid valve annular diameter was significantly decreased in patients who underwent ASD percutaneous device closure in comparison with a surgical group (P = 0.004). Conclusion: The results of this study showed that percutaneous ASD2 device closure will results in better RV function in comparison to surgical closure
