Cardiac Tamponade Complicating Postpericardiotomy Syndrome

We present 2 children who developed postpericardiotomy syndrome (PPS) and the rare complication of cardiac tamponade after cardiac surgery, each requiring life-saving pericardiocentesis in the emergency department (ED). Each child presented with vomiting as a chief complaint, an initial sign that has not been reported previously. As the frequency of orthotopic heart transplants and other cardiac surgeries among children increases, it is likely that ED physicians will encounter PPS and cardiac tamponade with greater frequency, and it is imperative that it be recognized promptly and treated appropriately. We review PPS, cardiac tamponade, and the proper performance of a pericardiocentesis.
