Cardiac rupture is the most common cause of death from blunt chest injuries. According to parmley autopsy statistics, about 64% of closed heart injuries are due to heart rupture. calhoon’s report on closed heart rupture injuries accounted for about 5% of the 50,000 deaths on U.S. highways, and another report on autopsies of traffic accident victims found that up to 30% of the deceased had heart rupture. The mechanism of cardiac rupture is: acute tearing of the heart due to compression by direct violence; contusion and bleeding of the heart leading to myocardial necrosis, softening, and rupture occurring days after the injury, both so-called delayed rupture. The free wall of the heart is the preferred site of cardiac rupture, and patients often die from acute cardiac compression; if the pericardium and mediastinal pleura rupture simultaneously, they die from hemorrhage. A left ventricular rupture will kill within minutes, a right ventricular rupture may kill within 30 minutes, and an atrial rupture may survive for a longer period of time. Rupture of the right atrium can also be triggered by blunt abdominal trauma. Cardiac penetrating injuries and foreign body storage are critical and serious cases of thoracic trauma, mostly caused by sharp force injuries from sharp knives, gunshots, shrapnel, and in China stab wounds are common; every atrium can be involved, with the right ventricle being the most common. Most of the injured die before reaching the hospital, and if they are still alive when they reach the hospital, the survival rate is 80-90% with timely treatment. For cardiac penetrating injury, most scholars believe that not because of the time-consuming examination, trauma located in the cardiac danger zone (the triangle area between the sternal angle of the anterior chest area and the line of the nipple on both sides) should be highly alert, and surgical exploration should be performed as soon as possible when there are signs of hemopericardium or Beck’s triangle, shock, progressive hemothorax, and emergency dissection is the key to successful treatment, and the danger of delayed treatment is much greater than negative exploration results. When the foreign body is retained in the heart, it is not easy to remove it before dissection. For the hemopericardium that is admitted to the hospital for many days after the injury, surgery should also be performed, which can prevent infection and residual traumatic constrictive pericarditis; when cardiac arrest occurs before surgery, emergency open-heart cardiac compressions must be done to release the heart compressions and temporarily control the bleeding site with fingers to improve the cardiac output. In this case, extracorporeal cardiac compressions are ineffective and aggravate pericardial compressions.
