Feasibility of Transcatheter Closure of Large Secundum Atrial Septal Defect with Absent Superior or Inferior Rim

Figure 2

(a) TEE imaging in long-axis bicaval view demonstrates a large secundum ASD with an absent superior rim. (b, c) TEE imaging in long axis bicaval view demonstrates large secundum ASD with color follow mapping after inflation of the covered CP-stent creating a new superior rim (red arrow) with the clear struts of the stent (blue arrow). (d) TEE imaging in modified long axis bicaval view clearly demonstrates the struts of the covered CP-stent (blue arrow) creating a new superior rim (red arrow) which has been captured by two discs of the Occlutech septal occluder size 40 mm (red arrow).
