The role of transesophageal echocardiography in transcatheter closure of secundum atrial septal defects by the Amplatzer septal occluder

Usefulness of cardiac computed tomography in transcatheter closure of atrial septal defect with amplatzer septal occluder

“…Even though TEE can show the entire anatomy of an ASD and facilitates monitoring of transcatheter procedures for implantation of ASO [1,11] it is associated with some inconveniences. Ko et al reported that there were no significant differences between cardiac CT and TEE in measurement of ASD size.…”

The Role of Cardiac Ultrasound in Stem Cell Therapy

“…Transesophageal echocardiography allows excellent real-time visualization of myocardium and can be done at the time of cardiac catheterization. This technique is often used during the closure of atrial septal defects [6] and could be similarly used to visualize myocardium at the time of stem cell injection. However, thus far, this has not been significantly employed in stem cell trials.…”

“…In particular, imaging can be used to (1) define the presence and severity of phenotype to be treated, (2) guide the delivery of therapy, (3) follow the course of disease and evaluate the effects of therapy, (4) provide labels and define mechanisms of therapy, (5) evaluate survival and function of engrafted cells, and (6) perhaps to facilitate the process of cell therapy. Furthermore, imaging has the potential to determine the engraftment, survival, and local function of cell therapy and to identify the mechanism of benefit.…”

The reliability of transthoracic and transesophageal echocardiography in predicting the size of atrial septal defect

“…Surgical repair was once considered the best treatment (2,3), but insertion of a septal occluder has gradually become an alternative (4)(5)(6). Accurate measurement and detailed anatomic delineation of ASD are essential for successful transcatheter closure (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17).…”
