Abstract:
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.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
