Coronary Sinus Rupture Due to Blunt Cardiac Trauma.

We present a very rare case of devastating blunt cardiac trauma with large right atrial rupture, contusion of the right atrioventricular groove, and coronary sinus tear. Surgical repair was successfully performed by urgently establishing cardiopulmonary bypass via the femoral vein and artery simultaneously with a median sternotomy. (Level of Difficulty: Intermediate.).
