Isolated fracture of the ventricular septum after blunt chest trauma.

Isolated rupture of of the ventricular septum after blunt chest trauma is a very rare traumatic affection. A 21-year-old man was admitted to our hospital because of blunt chest trauma and a forearm fracture. Initial echocardiography did not show any intracardiac or extracardiac pathologic lesions, but 12 hours later this examination was repeated because of the onset of a holosystolic murmur. An unusual traumatic rupture of the ventricular septum was demonstrated. The hemodynamically stable condition of the patient allowed surgical repair to be performed 3 months later.
