A hidden tear: Survival following blunt right atrial appendage rupture without external chest trauma

This case highlights the diagnostic challenge of blunt cardiac injury in the absence of apparent external chest trauma. It emphasizes the importance of maintaining a high index of suspicion for occult cardiac injury in patients with unexplained hypotension following high-energy mechanisms, even when chest imaging and exam findings are discordant. Early surgical intervention remains critical for survival in these rare but potentially survivable injuries.
