Management of Penetrating Cardiac Injuries

Penetrating cardiac injuries represent one of the most time‐critical and lethal forms of trauma, requiring seamless coordination from prehospital first response to definitive surgical repair. Incidence varies geographically, with stab wounds predominating in some regions and gunshot wounds in others. Rapid identification of pericardial fluid and haemodynamic compromise through ultrasound and clinical examination underpins triage. Prehospital management focuses on haemorrhage control, permissive hypotension and minimising scene time. On arrival at a trauma centre, resuscitation adheres to damage‐control principles including blood product administration and point‐of‐care imaging. Surgical approaches range from left anterior thoracotomy for emergency department access to median sternotomy in the operating theatre. Techniques include pericardiotomy, direct suture repair of cardiac lacerations and, where indicated, cardiopulmonary bypass. Postoperative care involves intensive monitoring for arrhythmias, myocardial dysfunction and effusion. Outcome determinants encompass transport interval, presence of cardiac tamponade, number of chambers involved and associated injuries. Advances in multidisciplinary protocols and regionalised trauma systems have incrementally improved survival, yet mortality remains high without prompt intervention.

Research from Nature Portfolio

Recent analysis of over 250 autopsy reports in a major urban centre has illuminated the sociodemographic and logistical factors that most influence survival in penetrating cardiac trauma. Findings reveal that incidents peak on weekends and after hours, with a quarter of victims dying at the scene. Prehospital transport by private means correlated with better vital signs on admission, while increased transit time, peripheral location of injury, multiple chamber involvement and gunshot mechanisms were linked to higher mortality. This work underscores the value of integrating demographic mapping and response‐time analysis into trauma system planning, advocating for targeted reinforcement of emergency infrastructure in high‐risk zones.

The graph below shows the total number of articles in management of penetrating cardiac injuries across all publications each year (not limited to Nature Index journals).

Technical terms

Penetrating cardiac injury (PCI): Trauma that breaches the pericardium and myocardial wall, risking haemorrhage and tamponade.

Cardiac tamponade: Accumulation of fluid in the pericardial sac causing impaired ventricular filling and obstructive shock.

Focused Assessment with Sonography for Trauma (FAST): Rapid bedside ultrasound protocol to detect free fluid in the pericardial and pleural spaces.

Emergency department thoracotomy (EDT): Immediate thoracic incision in the emergency department to access and control catastrophic chest bleeding.

Injury Severity Score (ISS): Anatomical scoring system that quantifies overall trauma burden to predict mortality risk.
