title: Successful surgical management of a double-chambered left ventricle in a 13-year-old girl: a report of a rare case.
abstract: BACKGROUND
  Double-chambered left ventricle (DCLV) is a rare congenital anomaly, and only a few cases in which a 2-chambered LV is separated by the interventricular septum or an abnormal muscle bundle have been reported in the literature. Frequently, such cases are diagnosed when a patient is admitted to hospital for the evaluation of a cardiac murmur, and most of these patients have isolated DCLV.
  
  
  METHODS
  We describe the case of a 13-year-old girl with DCLV who had twice undergone operation, including mitral valve replacement, in our institution.
  
  
  RESULTS
  No gradient was found after surgical resection of the hypertrophic floating mass, and the patient's symptoms disappeared.
  
  
  CONCLUSIONS
  Surgical resection can be carried out in patients with DCLV when done sufficiently early, and careful echocardiographic examination is important in a continuing follow-up. Surgeons should keep in mind the possibility of a recurrence of DCLV.
