about 75 y old man with condition after two occult cerebral infarction. A PFO with small left-right-shunt was documetated a few weeks ago.
You can see the implantation of a PFO-occluder system by colleagues in another hospital. Despite a normal \"stress-test\" (push and pull of the occluder-system via implantation catheter without dislocation of occluder) there was a dislocation of PFO-occluder in the left atrium.
This is a rare but a typical complication of that procedure. Via special catheter-system it could do an extraction of that system succesfully (not shown).
