Background Left ventricular penetrating injuries are rare but often lethal. Transport times greater than 30 min have been shown to increase the injury severity; thus early recognition of cardiac tamponade, prompt pericardial decompression, and control of cardiac hemorrhage are mandatory. Methods We retrospectively reviewed our record to include patients with penetrating trauma of the heart. Results Four hemodynamically unstable young male patients with left ventricular penetrating injury of the heart were referred to our unit between January 2007 and December 2015. Median time from trauma to surgery was 16 min (range 14–21). A cardiorrhaphy through sternotomy with no extracorporeal support was performed. We had no in-hospital mortality. Conclusion According to our experience, in patients with hemodynamic shock and penetrating cardiac injury, a timely recognition of injuries and referral to the closest thoracic surgery unit may increase patient survival if it is located closer than a level I trauma center.
