Tamponade after open-heart surgery with percutaneous cardiopulmonary support

Abstract

A 56-year-old man presented with late cardiac tamponade appearing on 9 postoperative day after weaning from percutaneous cardiopulmonary support. He had been referred to our hospital for congestive heart failure. He underwent aortic valve replacement and fell into postcardiotomy low output syndrome. He could not be weaned from extracorporeal circulation, and we had to use an intraaortic balloon pump and percutaneous cardiopulmonary support On postoperative day 9, percutaneous cardiopulmonary support was successfully withdrawn without problems, but he showed signs of superior vena cava syndrome after the cannulas were removed. An echocardiogram also showed cardiac tamponade. When the wound was reopened, a lot of old clots had compressed the right atrium and, after clot removal, the patient’s hemodynamic state improved markedly. It is important to be aware that percutaneous cardiopulmonary support may conceal hemodynamic deterioration due to cardiac tamponade and to take care that a patient does not experience hemodynamic deterioration after percutaneous cardiopulmonary support withdrawal.
