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

Figure 5

(a, b) IVC angiogram in frontal and lateral views demonstrates the diameter of the IVC at its entrance into the right atrium in order to select the proper size of the balloon. (c, d) Cine angiogram of the heart in frontal and lateral projections demonstrates the inflated Z-med balloon 25 × 40 mm at the entrance of the IVC to document that the inflated balloon can created an inferior rim. (e, f) Cine angiogram of the heart in frontal and lateral projection demonstrates the inflated uncovered CP stents at the entrance of the IVC into the right atrium. (g, h) Cine angiogram of the heart in frontal and lateral projection demonstrates proper implantation of uncovered CP stent at the entrance of the IVC, creating an inferior rim which makes the closure of the ASD secundum with an absent inferior rim possible and effective by the atrial septal occluder.
