Mid-term results of aortic root repair using the reimplantation technique: our single-center experience

Background: This study aims to report early and midterm results of valve-sparing aortic root replacement using the reimplantation technique. Methods: A total of 54 consecutive patients (44 males, 10 females; mean age 58±12.3 years; range 26 to 80 years) who underwent valve-sparing aortic root replacement using the David-V technique performed by a single surgeon at a single center between January 2008 and June 2015 were retrospectively analyzed. Results: The in-hospital mortality rate was %1.9. The median follow-up was 57.5 (range, 29.5 to 77) months. Two patients developed severe aortic insufficiency during the first year following surgery and underwent aortic valve replacement. Estimated survival rates were 96.2±0.03%, 96.2±0.03% and 96.2±0.03% at one, five, and seven years, respectively. Moderate to severe aortic insufficiency-free survival rates were 96.2±0.03%, 96.2±0.03% and 96.2±0.03% at one, five, and seven years, respectively. Survival rates free from valve related re-operation at one, five, and seven years were 96.2±0.03%, 96.2±0.03% and 96.2±0.03% respectively. Conclusion: Our early and mid-term results of the valvesparing root reimplantation procedures for aortic root aneurysms are excellent.
