title: Unexpected resistance to external cardiac compression may signal pericardial tamponade.
abstract: Pericardial tamponade associated with central catheters is often lethal, unless promptly identified. We report our experience with two infants who suffered this complication but were successfully resuscitated. In each case, associated radiographs showed the tip of the central catheter beyond the superior vena cava-right atrium (SVC-RA) junction. Identifying the clinical triad of (1) sudden cardiovascular collapse unresponsive to usual resuscitative measures, (2) thoracic transillumination not suggestive of air leak, and (3) unexpected resistance to external cardiac compression led to the working diagnosis of pericardial tamponade and therapeutic pericardiocentesis. Prompt recovery followed. Central catheters within the RA seem prone to cause pericardial tamponade.
