OBJECTIVE: Since 1976 a number of similar transvenous atrial septal defect
occlusion systems have been developed and applied to prevent surgical
intervention with extracorporeal circulation and the complications
involved. One of them is the so called atrial septal defect occlusion
system (ASDOS-device; Dr Ing Osypka, Germany). METHOD and RESULTS: In our
institution, eight ASDOS-devices were implanted in adults during the last
year. In six individual cases, these devices were explanted because of
thrombosis, residual shunts, deformations of the umbrella, disconnection of
the system and atrial perforation with hemopericard. This occured 17-380
days after the implant. The surgical removal was uncomplicated in all
cases. CONCLUSIONS: Because the complication rate of the ASDOS-device was
unacceptably high, surgical repair was preferred.
