Heart Under Pressure: From Scene to Scalpel in Cardiac Tamponade From a Left Ventricular Stab Injury

Penetrating cardiac injuries carry exceptionally high mortality, especially when the left ventricle is involved, and survival hinges on rapid diagnosis and immediate surgical intervention.We describe a case of penetrating cardiac trauma with acute tamponade, emphasizing the role of coordinated care from scene to operating theatre.A 30-year-old male presented with multiple precordial stab wounds, in hemorrhagic shock with severe hypoxemia; prehospital teams prioritized rapid stabilization and transport.On arrival, extended focused assessment with sonography for trauma (eFAST) identified left hemopneumothorax and circumferential pericardial effusion consistent with tamponade, and the massive transfusion protocol was activated.Emergency median sternotomy revealed a grade IV left ventricular laceration, which was repaired primarily without cardiopulmonary bypass, and the patient recovered well, with progressive hemodynamic stability and favorable metabolic parameters postoperatively.This case illustrates that survival from penetrating left ventricular injury requires rapid diagnosis via point-of-care ultrasound, immediate median sternotomy, and intensive postoperative management, and demonstrates that favorable outcomes are achievable through coordinated multidisciplinary care within an organized trauma system.Penetrating cardiac injuries remain time-critical emergencies, and early recognition via point-of-care ultrasound, prompt surgical access, and a well-rehearsed trauma protocol can achieve survival even when severe ventricular injuries are present.
