MDCT Evaluation After Closure of Atrial Septal Defect with an Amplatzer Septal Occluder

Abstract

In anatomic regions that cannot be confidently evaluated with transthoracic echocardiography, MDCT is useful for evaluating Amplatzer septal occluders for protrusion, migration, and residual shunt. Radiologists should be familiar with the imaging protocol and interpretation.
