Atrial rupture without other major injury following blunt chest trauma is rare, but carries high mortality rate. Here we report 3 cases of blunt atrial rupture. All patients presented with hypotension and loss of consciousness. ⋯ In most reported cases, the cardiac tear has been repaired without using cardiopulmonary bypass. However, it is difficult to diagnose location of the tear, therefore, the repair became safer using cardiopulmonary bypass for the patients with cardiogenic shock. This article has described the mechanisms and generation of blunt chest trauma lesions.
