Abstract:
A 87-year-old man suddenly complained of dyspnea and fell into shock just after tee-shot. UCG revealed a large amount of pericardial effusion and good wall motion of the heart. Enhanced CT scan didn't prove any intimal flaps in the aorta. With cardiopulmonary bypass stand-by, we opened the pericardium and found a small laceration in the main pulmonary artery. The site of the laceration corresponded to a hard and sharp pericardial reflection ridge. We speculated that the difference of deceleration power between body and the heart resulted in pendulous or torsional motion of his heart. Supposedly the mutual actions between sharp pericardial reflection ridge and strange motion of the heart injured his main pulmonary artery.

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.
