Penetrating cardiac injuries: What you need to know.

Despite significant advances in trauma surgery in recent years, patients sustaining penetrating cardiac injuries still have an overall survival rate of 19%. A substantial number of deaths occur at the scene, while approximately 40% of those reaching trauma centers survive. To increase survival, the key factor is timely intervention for bleeding control, pericardial tamponade release, and definitive repair. Asymptomatic patients sustaining precordial wounds or mediastinal gunshot wounds should be assessed with chest ultrasound to rule out cardiac injuries. Shock on admission is an immediate indication of surgery repair. Patients admitted in posttraumatic cardiac arrest may benefit from resuscitative thoracotomy. The surgical team must be assured that appropriate personnel, equipment, instruments, and blood are immediately available in the operating room. A left anterolateral thoracotomy, which can be extended to a clamshell incision, and sternotomy are the most common surgical incisions. Identification of cardiac anatomical landmarks during surgery is vital to avoid complications. There are several technical options for bleeding control, and the surgeon must be trained to use them to obtain optimal results. Ultimately, prioritizing surgical intervention and using effective resuscitation strategies are essential for improving survival rates and outcomes.
