Keywords: Atrial Septal Defect

Six female patients aged from 19 to 73 years, with ostium secundum atrial septal defect underwent closure procedure with Amplatzer septal occluder device. Three-dimensional Echocardiography (3D-TEE) was done during the procedure or one day after the procedure. 3D-TEE provides incremental value over Two- dimensional trans-esophageal echocardiography in measuring Amplatzer septal occluder disc sizes and correlates well with manufacture device size. 3D-TEE will surely prove to increase the technical efficiency and it will become an important tool for the interventionists for periprocedural evaluation of device closures. ►Implication for health policy/practice/research/medical education: This paper is aiming to provide the recent advances in the field of Echocardiography and introducing new methods of measurement for peri procedural ASD closure devices. ►Please cite this paper as
