Clinical Practice and Cases in Emergency Medicine

Blunt cardiac injury encompasses multiple injuries, including contusion, acute valvular disorders, and chamber rupture.^{Blunt traumatic cardiac rupture is a very rare occurrence accounting for 0.5% of blunt trauma cases with a very high mortality rate.Coexisting pericardial rupture in patients with cardiac rupture obscures the diagnosis and contributes to mortality.False negative pericardial ultrasound secondary to a concomitant pericardial laceration and subsequent decompression of the cardiac hemorrhage into the ipsilateral pleural space is extremely rare and has only been recently described in the literature.This image depicts a case of traumatic right ventrictular rupture from blunt cardiac injury and highlights the importance of considering an underlying cardiac injury in the presence of a negative FAST pericardial window in patients with a traumatic hemothorax.}
