Cardiac tamponade is an acute life-threatening condition that predominantly involves the intra-pericardial space; however, an expanding mediastinal hematoma can also sometimes cause cardiac tamponade. Here we describe the case of a 45-year-old male driver in whom a traffic accident resulted in rupture of the left internal thoracic artery (ITA), extra-pericardial hematoma, and sternal fracture. After resuscitation, he was scheduled to undergo angio-embolization to repair the ruptured left ITA, but he suddenly developed cardiac tamponade that required a decompressive sternotomy. Nevertheless, the patient had an uncomplicated recovery, and this case suggests that extra-pericardial cardiac tamponade should be considered as a possible consequence of retro-sternal hematoma due to traumatic ITA rupture.

A 55-year-old man underwent emergent sternotomy due to cardiac tamponade occurring just after an accidental fall from a 10-m height. Tricuspid valve regurgitation was found on echocardiography while he was on mechanical ventilation after the operation. The patient was weaned successfully from mechanical ventilation after tricuspid valve repair under cardiopulmonary bypass. Traumatic tricuspid valve regurgitation is a rare blunt chest injury and its symptoms occur late. Tricuspid regurgitation should be considered as a reason for failure to wean from mechanical ventilation after blunt cardiac trauma.
