Amplatzer septal occluder

(A) Angioscopic system evaluating surface of the atrial septal occluder (ASO): low-molecular-weight dextran is infused from the guiding catheter and the tip of the GuideLiner extension catheter during observation. (B) Neointima covering most of the 22 mm ASO 6 months post implantation. (C) Around the central part of the device, the struts were exposed with marked thrombus formation. Guidewire marked by asterisks (*) in panels B and C.
