[Right Atrial Rupture due to Blunt Trauma;Report of a Case].

The survival rate of cardiac rupture due to blunt trauma is generally low. We report a case of surgical treatment of blunt cardiac trauma. A 55-year-old man was admitted to our hospital for blunt trauma due to a car accident. His hemodynamics was compromised due to cardiac tamponade. The patient underwent pericardial drainage by small subxiphoid incision. Although about 400 ml of blood was evacuated, hemorrhage was still continuing. After full sternotomy, we found a 3 mm tear in the right atrial appendage and sutured it easily without cardiopulmonary bypass. The patient recovered uneventfully and was discharged on the 10th postoperative day. He is now leading a normal life.
