[Surgical treatment for the patient with atrial septal defect and Andersen syndrome].

An 18-year-old girl with atrial septal defect and Andersen syndrome is reported. Andersen syndrome was described as a hereditary disease characterized by periodic paralysis, prolongation of the QT interval with ventricular arrhythmia and characteristic physical features including low set ear and micrognathia. We successfully performed cardiac operation for this rare associated malformation.
