In this study we found that trans-oesophageal echocardiogram images were better than transthoracic echocardiography and especially evaluating rims of arterial septal dedects and thanks to that helping effective indication of atrial septal closures. Right ventricular morphology and function improved after intervention, but not good, probably needs more time for morphological right ventricle returning to normal and improving right ventricular function better.
