Isolated ventricular septal perforation (VSP) due to blunt trauma is rare. We report the case of successful repair of VSP due to blunt chest trauma. The patient was a 7-year-old boy whose chest had collided against the bottom bar of the window shade. He had no obvious injury on the surface of his body and no cardiac murmur at all. However, a pansystolic murmur was heard within a month, and a color Doppler echocardiogram revealed left-to-right shunt flow through a VSP. He underwent surgery three months after the blunt chest trauma. An approximately 10-mm tear with fibrous edges was found in the apical septum, and it was closed by left ventriculotomy using an expanded polytetrafluoroethylene patch. The patient’s postoperative course was uneventful.
