title: Bentall and De Bono surgery for correction of valve and ascending aortic disease: long-term results.
abstract: OBJECTIVE
  A retrospective study was performed in a series of consecutive patients who underwent a Bentall and De Bono procedure.
  
  
  METHODS
  Data were removed of medical records and follow-up data were obtained from clinical records and direct contact with patients. A total of 39 patients were studied between January 1996 and December 2005.
  
  
  RESULTS
  The median age was 47 years (range 14-70). There were 33 males and six females. Eleven (25.5%) patients presented Marfan syndrome and one (2.5%) Turner syndrome. Nineteen (48.5%) patients had hypertension, eight (20.5%) had history of smoking, six (15.5%) had history of alcoholism, eight (20.5%) had dyslipidemia, two (5.0%) had diabetes and one (2.56%) had myocardial infarct previously. Twenty-eight (72%) patients were in II-III NYHA class in the moment of the surgery. Annulo-aortic ecstasy was present in 14 (35.9%) patients and aortic aneurysms in 16 (41%). The median time in intensive care unit was 8.79 days with range 2-23 days. Four (10.0%) patients underwent an emergency operation and 35 (90%) elective. The overall hospital mortality was 5% (2/39). The event-free survival is 94.87% at 1 year and 84.61% at in 5 and 10. The median time of follow-up was 46.5 months (range 14-120 months).
  
  
  CONCLUSIONS
  The Bentall and De Bono technique obtained excellent results in the short-term and long-term, which support the continued use of the compositive graft technique as the preferred method of treatment for patients with aortic root disease. Our findings confirm the current literature data.
