Blunt cardiac rupture of left ventricular apex without external chest injury in a young man: a case report

Cardiac rupture in blunt cardiac injuries, though uncommon, can be fatal. A particularly rare occurrence is blunt cardiac rupture of the left ventricle without external chest injury. Herein, we report a case of cardiac rupture without external chest injuries in a 21-year-old man who died after a physical altercation. The cause of death was attributed to cardiac rupture caused by blunt force. We analysed the differential diagnoses of cardiac rupture with intact pericardium, including cardiac diseases, blunt chest injury, cardiopulmonary resuscitation, and Takotsubo cardiomyopathy. Additionally, we discussed the relevant factors for cardiac rupture in this case, including sudden enormous force, cardiac cycle, chest wall compliance, and alcohol consumption. Furthermore, we highlighted that no explicable cause other than cardiac rupture accounted for the death.
