Introduction: For safe percutaneous ASD device closure, the rims surrounding the defect should be appropriate to allow the device to firmly hang onto the atrial septum. Two-dimensional transthoracic echocardiography (2D TTE) is adequate in detecting these defects, but the images obtained can lack the detail necessary to precisely measure their size, shape, and location. Three-dimensional transthoracic echocardiography (3D TTE) provides enhanced visualization of the defect in the majority of patients. The primary objective of the study is to estimate the proportion of cases where device was deployed safely as per the device size predetermined by pre procedure 3D TTE and to compare it with current gold standard imaging modality, ie, 2D TEE.
