title: Unraveling the paradox of cardiac tamponade: case presentation and discussion of physiology.
abstract: A 53-year-old man on warfarin for postoperative pulmonary embolism presented with chest pain and was found to be in cardiac tamponade due to an atraumatic haemopericardium. Findings of tamponade and a novel approach to the pathophysiology of pericardial disease to explain these finding are presented.
