A 38-year-old man was sent to the emergency service of another hospital for an accidental nail-gun shot injury of the chest. Echocardiography and computed tomography showed that the left and right ventricle were penetrated by the nails. Emergency surgery was performed by median sternotomy, and the nail in the right ventricle was removed without cardio-pulmonary bypass and the nail in the left ventricle was removed under cardio-pulmonary bypass. He was discharged uneventfully 10 days after the accident.
