title: Subvalvular circular annuloplasty as a component of aortic valve repair.
abstract: OBJECTIVE
  A recently developed technique of aortic annuloplasty, together with immediate postoperative results, are described.
  
  
  METHODS
  Between June 1998 and October 2000, 26 patients (22 men, four women; mean age 59 years) with chronic dominant aortic regurgitation (AR) underwent aortic valve repair in which subvalvular circular annuloplasty was used. A concomitant repair technique was performed in all patients. Operative results are summarized, along with perioperative changes in NYHA status and echocardiographic findings.
  
  
  RESULTS
  There were no hospital deaths. Mean cardiopulmonary bypass time was 139.0+/-32.8 min, and mean aortic cross-clamp time 106.0+/-33.2 min. Mean postoperative NYHA class at one month postoperatively was 1.0. Mean postoperative AR grade at hospital discharge was 0.9+/-0.7, which represented an improvement over preoperative grade (p <0.0001). LVEDD was reduced from 6.3+/-0.9 cm to 5.1+/-1.1 cm (n = 25; p <0.001), and LVEF from 64.3+/-9.2% to 51.9+/-11.0% (n = 26; p <0.0001). Annulus size was reduced from 2.6+/-0.3 cm to 2.2+/-0.2 cm (n = 18; p <0.0001).
  
  
  CONCLUSIONS
  A new technique of aortic annuloplasty as a component of aortic valve repair was developed and used successfully in 26 consecutive patients. The short-term postoperative outcome was satisfactory.
