[Surgical Repair for the Ventricular Septal Perforation Following Blunt Chest Trauma;Report of a Case].

Ventricular septal perforation(VSP) after blunt chest trauma is rare. As the clinical symptoms and timing of presentation are varied, appropriate diagnosis can be difficult or delayed. An 86-year-old man presented with a traumatic VSP following a forestry injury. He showed a normal cardiac structure at the time of injury, but echocardiography after 9 days revealed VSP. He was treated successfully with surgical closure of the VSP.
