Cardiac Tamponade from Isolated Right Atrial Rupture: A Rare Presentation of Blunt Chest Trauma Without Rib Fracture

Cardiac tamponade resulting from blunt chest trauma is an emergent and life-threatening condition. Cardiac rupture from blunt chest trauma is not a common presentation, and more so in the absence of rib or sternal fracture. We present a case of blunt chest trauma, who presented with features of cardiac tamponade. Emergency sternotomy revealed a right atrial rupture near the appendage which was surgically repaired. The patient also underwent simultaneous splenectomy for Grade 4 splenic injury. The patient recovered uneventfully. Prompt recognition of the injury based on a high index of suspicion must lead to immediate surgical intervention in order for these patients to survive, even in the absence of specialized imaging investigations.
