defect.

The 2D study is also useful in defining the atrial septal rims [Figures 25 and 26] for suitability of
transcatheter device occlusion, although TEE or ICE in the catheterization laboratory is usually utilized for
this purpose.

Since there is an increased prevalence of deficient atrial septal rims, particularly in large ASDs [28,29] , a careful
evaluation of septal rims by TEE [Figure 27] or ICE should be performed in the catheterization laboratory
prior to device implantation.
