The account alleges that during an emergent percutaneous pericardiocentesis for life threatening cardiac tamponade, the drainage catheter could not be successfully introduced.The physician used a local anesthetic to numb the access area [ subxiphoid approach] of the patient's chest.A needle was then inserted, via "seldinger technique", under the guidance of an echo/fluoroscopy, into the patient's pericardial sack.A guidewire was inserted into the patient pericardium and the access needle successfully removed.When the physician tried to introduce the drainage catheter, over the "j" wire into the patient's pericardium, the drainage catheter would not allow the access wire through the catheter's inner limen.The account alleges that the distal part of the drainage catheter was obstructed.Another catheter was expeditiously prepped and successfully used to treat this patient.The patient tolerated the procedure well with no additional consequences to report.
