Abstract: Transesophageal echocardiography has been used throughout the procedure of transcatheter closure of atrial septal defect due to high resolution images as well as superior operator comfort in assessing device position. However, the centers, lacking the facility of intra-procedural transesophageal echocardiography, carry out the procedure using transthoracic echocardiography which may have higher chances of device malposition. In this case-series, we describe fluoroscopic features of device position or malposition which would prove beneficial to the centers in assessing device position in the transcatheter closure of atrial septal defect performed using transthoracic echocardiography.

Keywords: Transesophageal echocardiography, transthoracic echocardiography, fluoroscopy, atrial septal defect. Read more
