title: Ross procedure for complex left ventricular outflow tract obstruction.
abstract: BACKGROUND
  Complex left ventricular outflow tract (LVOT) obstruction in children continues to pose a significant therapeutic challenge to cardiac surgeons. The Ross procedure, in combination with resection of subaortic stenosis or a Konno type septal incision, is an important option for these difficult patients.
  
  
  METHODS
  Recently two children aged 14 and 5 years with LVOT obstruction involving combined subaortic and valvar stenosis underwent surgical correction using the pulmonary autograft. Clinical presentation, operative technique, outcome and intermediate follow-up are detailed.
  
  
  RESULTS
  One patient had resection of an isolated subaortic membrane in combination with a pulmonary autograft and the second a Ross Konno procedure. Postoperative hospital stays were without complication. Both patients were discharged at 5 days and have no significant obstruction nor semilunar valve insufficiency at 3 years' follow-up.
  
  
  CONCLUSIONS
  Pulmonary autografts can be used in combination with resection of subaortic tissue or a septal incision for reconstruction of complex left ventricular outflow tract obstruction. This technique renders excellent short term valve function, relief of obstruction, avoids anticoagulation and provides potential for future growth.
