title: Reconstruction of the ascending aorta and aortic root: experience in 45 consecutive patients.
abstract: BACKGROUND
  Patients with aneurysms of the ascending aorta or aortic root may have associated aortic insufficiency (AI). We reviewed our experience with aortic root remodeling and reconstruction of the sino-tubular junction.
  
  
  METHODS
  Forty-five patients were operated on between July 1995 and September 1998. Transesophageal echocardiography showed AI grade III or IV in 15 patients. Twenty-seven patients had replacement of all three sinuses, 10 of one or two sinuses. Reconstruction of the sino-tubular junction alone was performed in 8 patients.
  
  
  RESULTS
  There was one death at 28 days. Perioperative transesophageal echocardiography showed no or discrete AI in all patients. There has been one aortic valve replacement at day 4 postoperatively for cusp repair failure. Transesophageal echocardiography in 40 patients at a mean time of 12.5 months showed no progression of AI in 38 patients, and a grade II in 2. Clinical follow-up averaged 14.5 months. There have been three late, not procedure-related deaths. Thirty-six patients are in New York Heart Association functional class I. There have been no cases of endocarditis.
  
  
  CONCLUSIONS
  Aortic remodeling is successful in eliminating AI in patients with aortic root disease with minimal mortality and morbidity. Early echocardiography (1 year) has shown no progression of AI in 95% of cases.
