Device Closure of ASD

Before going to device closure of atrial septal defect, we will discuss a bit about the different types of atrial septal defects and a couple of transesophageal echocardiographic images of atrial septal defect. Device closure of ASD is suitable for secundum ASD with a good rim all around for holding the two discs together. Transesophageal echo is done to assess the superior, aortic, and mitral rims as well as the total septal length.
