Three-Dimensional Printing as an Aid in Transcatheter Closure of Secundum Atrial Septal Defect With Rim Deficiency

Absent posteroinferior and anterosuperior atrial septal defect rims: factors affecting nonsurgical closure of large secundum defects using the Amplatzer occluder. Figure 2. The personalized 3-dimensional printed heart model was produced on the basis of multislice computed tomography (A), and in vitro trial occlusion was achieved successfully with a 38-mm Amplatzer septal occluder (B and C). Figure 1. Multislice computed tomography showed that the superior (A) and anterior (B) rims were sufficient. However, a par-tial defect can be detected in the posterior-inferior rim (C, arrow). The distance from the atrial septal defect to the inferior vena was also sufficient (D).
